Legion Pro 7i Undervolting and Overclocking Optimization Guide for Max Performance

what's up and welcome back to another uh optimization guide with Gizmo slip Tech we're doing the legion Pro 7i which I have right here on the table you can see this bad guy right here um so this is the I9 13900hx with RTX 4090 variant and we're going to be doing all of these things here today so we're going to uh first pre-test Cinemax R23 with time spy and uh with uh all of our stock settings and we're gonna then we're gonna go ahead and set up a laptop cooler we're gonna undervolt the I9 3900hx we're going I'm going to show you how to under volt it using throttle stop today which had an update um about I think in May so a couple months ago and that one actually that update actually lets you use 13th gen processors on throttle stop so we're going to test that out today I'm going to show you the steps by step um for adjusting the undervolt settings and then we're going to also go through the bios of the Legion Pro 7i which is gonna you have to change some settings in the Bios I didn't add that in here I should probably make sure to add that in to our time thing here there we go so update bio settings yeah so that's a very important so that you don't miss out you got to make sure you adjust those bio settings otherwise the CPU will probably be locked down you won't be able to adjust the undervolting settings on that CPU um then we're going to go ahead and test an image R23 with the undervolt and overclock applied and if you don't know what undervolting is undervolting is essentially telling the CPU to run at a the same amount of wattage but at a higher speed on the processor thereby giving you more performance per watt going through your CPU and of course if if you are trying to there it used to be that when you undervolt it it would reduce your temperatures on your CPU but that's not really the case anymore um because before it would also reduce your wattage at the same time when you're undervolting nowadays the way it works is basically you're telling the CPU to go faster at the same amount of Watts which gives you more performance for the same amount of wattage which is great um and yeah so I think uh I think this laptop has a lot of potential and I'm pretty sure we can get close to 10 percent gains if you optimize your legion Pro 7i properly uh and that's a big deal when you're spending three thousand dollars because a 10 gain is potentially like you know a 400 500 worth of upgrade uh basically in your laptop and it and theoretically it should uh not affect the long-term liability or viability of the laptop because you're running at the same amount of heat going through the system um okay so demon slump says oh wow just in time just got this deal from b h uh it hasn't shipped yet but I'll definitely refer to this later nice uh Hi man what are you gonna do the legion slim five I don't know it just came in the mail today so it'll probably be uh next week when I get to the legion uh Lenovo slim five that's going to uh for the unboxing review because I'm gonna I'll be busy the next few days and then we'll be able to I'll be resuming my live streams uh probably Wednesday next week all right yeah King Dragon finally I'm optimizing this uh well there's a lot of struggle I had getting the optimization to work on the legion Pro 5. custom mode wasn't working we're gonna go through and go over how to use custom mode I suppose I should do that as well um we're going to talk about uh I guess we should also show uh Lenovo Vantage best setup so we're gonna we're gonna keep adding to this uh objectives list today um for this because uh you know it's kind of um you know these live streams are a little bit fluid but also you know we're I gotta try I try to have a structure for you for outline for us to follow um am I gonna review the aorus 1517 I did the aura 17 already tcam um and the aura 7. uh eventually I hope to do the RS 15 yes okay so we are ready to just dive right into it let's go ahead and pre-test cinematch R23 um and so this is the legion laptop right here in front of me and uh this guy has some of the best specs for the money that you can get all right so uh definitely one of the laptops I can recommend uh wholeheartedly on the channel and especially if you're into a high looking for a high performance laptop I don't think that the legion is the Pinnacle of most premium laptop features out there but it provides excellent value for the money and one of the nice things about this Lenovo Legion is the Vantage software which it provides a lot of customizability that a lot of other laptops don't have and some of them do but obviously but many of them do not okay so let's quickly talk about how do you get just basic all right we're talking basic performance gains all right in the Lenovo Vantage software you've got CPU overclock which this is a new feature I've actually never tested this feature never pre-tested this this is this was not in here when I initially did the review install the driver to activate CPU overclocking interesting well let's try installing this if we can no I don't this is interesting uh so yeah this is it says install the driver but there's no driver here to install I guess this is the driver to install interesting yeah so this is this is something new um that said the primary the primary feature that I've tested in the past with my uh hey okay why is this pop-up happening okay keep running gaming driver feature okay so let's try to go back can we enable this now it said restart required okay maybe we gotta restart the system now I don't know um so we're going to show today I don't know which how Lenovo is using that CPU overclocking or how they do the CPU overclocking in this but I am going to show you how to use throttle stop to under volt and overclock your CPU and then I'm going to show you how to use MSI afterburner paired with HW info to be able to optimally overclock your GPU for either most performance or most uh I guess best thermals those would be the two different options we're going to look at we're also going to be using a is GT500 laptop cooler after this initial testing um all right so there we go so if you guys if Chad has more information about how they do this CPU overclocking I'm very curious okay so we did successfully install that driver and this is the text that it says overclocking is a change to factory specifications of the computer this changed my cause malfunction or damage to the computer components loss of data which there's a factual warranty will not apply Advanced overclocking options are only configuration tools that do not guarantee with the performance and stability of the device after the configuration please make sure you understand the relevant technical knowledge and risk before use okay so um this is giving us access to your core voltage offset and your efficiency e-cors offset that's cool and then you also have actual uh uh actual clock speeds here that you can change I doubt I doubt you know these kinds of let me zoom out a little so you can see this a little better I doubt that you're actually going to get any core clocks to change here um just because you're telling it to Target a higher core clock on the e-course for example it's not going to actually go higher but you've got a core voltage offset and an e-core offset and inside a throttle stop we actually have uh additional settings that you can set beyond that you can do CPU core which I already have and offset in here and my throttle step of -160 which so far has been stable on my P cores my P chord cache minus 125 also stable sa agent minus 50 Intel GPU minus 30 igpu on sliced minus 30. CPU e core minus 100 is what I currently have going the biggest thing that I'm not seeing in the Lenovo Advantage software here is that there is no cash offset so the P core cache offset is not in here as an option and that can give you a nice extra bit of performance being able to undervolt the cache so uh let me go and turn these lights off behind me because I am noticing some reflection there uh weird I have the 7i and no CPU overclock option uh yeah so my guess is because you didn't go into the BIOS and enable it which we're going to go over how to do that uh here in a moment but first we're going to get our Baseline overclock and all of that done so um so right now I'm going to set this to nothing so I have I have a preset here in throttle stop I'm going to set it to nothing so zero this is nothing is undervolted in this configuration so we're going to go ahead and save that we should have uh zeros now in our offsets here inside of HW info let's verify that we no longer have an overclock being applied okay so it's still it's still of uh undervolting everything so we might have to manually adjust these things so I'm guessing until you actually um until you actually tell it to change it to a different value than it's gonna keep my original undervolt now I have throttle stop configured so that it will always start up at the beginning when you log into windows and I'm going to show you how to do that as well as well as pick which profile inside of throttle stop is activated now let me see if that applied things I might need to actually manually adjust the undervolts here okay so now we have zeros for our offset so this is how you can tell if your system is actively being undervolted you actually have to close HW info for it to pull this data it does not pull it after HW info is open but under the core I9 here you can see there's voltage offsets and you can expand this down to make it bigger and you can see each individual offset that you can add and you can see that right now we have nothing we have nothing activated for our offsets and uh I'm going to leave this just like this for right now all right and uh if we were to use this to to do our undervolting instead I'm pretty sure it would work but I'm not sure what they're using in the background to do this uh improper settings of overclocking with each irreversible damage press and hold the power button for 8 to 15 seconds to restart the computer and restore default parameters use restore default overclocking toggle and bio settings to restore default parameters okay so if you do encounter like a uh where the laptop will not turn on because you undervolted too far then you can hold the power button for 8 to 15 seconds to restart the computer and restore default parameters now it of course looks like restore default overclocking may also be needed I don't know why it's interesting that uh it's it's interesting that it's giving that option anyway so we are not going to apply the CPU overclock option here we are going to go to uh we're just going to put it in performance mode all right we'll put the laptop in performance mode and then we are going to go to um notice that we are in GPU mode dgpu there are a bunch of different modes here honestly I don't know the dgpu mode is actually going to improve things at all um for you because this does have an advanced Optimist with a mux switch and basically D GPU mode utilizes the mux switch to disable the integrated GPU entirely and you cannot switch to good battery life mode in this mode here so um hybrid mode is probably the best option there is igpu only mode as well which if you need for sure better battery life and you're not going to use the Nvidia GPU you can use this um as well which is nice to have that option because some laptops struggle to keep the Nvidia GPU disabled um during battery life mode which can really hamper your battery life so I like that it's an option that Lenovo gives us all right so let's go ahead and just we're not going to change anything there but in general best gaming performance will probably be in D GPU mode or in hybrid mode with Nvidia GPU selected obviously theoretically it should have no performance difference between those two in my opinion most likely Maybe basically dgpu mode disables the igpu which theoretically might slightly improve the uh the CPU performance because you don't have to run the integrated GPU but I don't know I have not seen any performance gains so far from changing that though I've not done detailed enough testing so all right so performance mode Let's go ahead and get our Baseline tests done cinematch R23 right now the laptop is flat on the desk with no extra Cooling let's get HW info loaded up someone was saying balance mode with AI actually beats performance mode I don't think so that was not my experience when I tested that but it might in certain applications if the AI is uh optimizing correctly uh hard to say okay all right here we are we're going to do uh some basic tests and we're going to see what we get for performance uh let's go and take a look at our P cores P cores right now doing 4.1 gigahertz 3.39 gigahertz all right so 4.1 gigahertz 3.4 gigahertz basically all right and let's go ahead and scroll down to our power output 164 watts of power so a lot of power coming through there 83 degrees on the CPU package 77 on this the course 29 545. so that's a pretty good score let's let the let's let's send it back to R23 run here with focusing on the window this is going to give us a bit more of a ideal type of a score we'll do like a few of these in a row and we'll get an idea of what our best case scenario is out of the box in performance mode 29 939 so just shy of 30k for that run um and I do want to point out that uh this CPU will push up to 165 watts of power on its own but um theoretically the short power limit is actually 190 but I never see it pull that much okay um 29 887. so again we've not broken 30 000 yet basically 29.9 K is where we're at right now 29 900 ish just a little more than that or a little under that and uh so if you were to keep running these you would eventually run into about thirty thousand there thirty thousand one hundred and thirty three if you if you keep running these continuously what you'll see is the CPU package power will drop to 140 Watts um eventually okay and what we're looking at here is again 4.1 gigahertz on the p-course 3.4 gigahertz on the e-cores which I'll be honest this is not especially this is not bad this is not amazing like like especially the the core clocks notice that since we're looking at HW info our score goes down just a little bit uh 29 300. and um so 4.1 on the P cores 3.39 on the e-cores and there we go there's 142 Watts let's see if it stays there a one now it's on 164. so it will you have to really continuously Pummel the legion Pro 7i in order to get it to drop to the 140 watt level um 28 900 that time but I did notice too that even if it's dropping to 140 it will oftentimes bounce up um higher than 140 temporarily and then go back down it just kind of wafts around the 140 to 145 150. um during these tests we're not continuously loading the CPU so yeah so just know that our our initial scores 29.9 K best score was just over 30 000. now doing 28 to eight all right so let's let's go ahead and get some thermal test done now let's see what we get for average temps um after a few minutes and average CPU clocks after a few minutes on this CPU 89 degrees right now on the CPU package power so that's not terrible but it's not great we're approaching 90 plus degrees on the package and uh thermal throttle is obviously going to be a hundred and the bigger the bigger Gap we can have between thermal throttling and not is generally better keeping the system cooler is generally better for CPU temps Lewis says we did hit core thermal throttling once on on four different cores it said we hit thermal throttling that's interesting but it shouldn't thermal throttle until we actually get higher so notice that our package power is only 135 right now 145 we're not pushing 165 Watts anymore and since we're not pushing 165 Watts anymore our our core package and CPU package temps are also going to come down so that's that's the good thing about only doing 140 Watts the system can run fairly cool considering the amount of wattage going through the system is reduced at 140. so I would expect these temps to not really go above this 85 range too much I guess we did hit we did hit thermal throttling for a moment there again it's interesting that it's thermal basically thermal throwing at 91 degrees which is very interesting I don't know um let's take a look at our clock speeds again so now we're doing 3.8 gigahertz on the P cores and let's see what let's Let It update again so 4.1 3.4 now down to 3.8 so 3.8 and 3.2 right now on the e-course so really we're losing work yeah that's those are really not great numbers I mean they're good they're obviously very good it's a lot of performance but I think these numbers can be significantly improved so real quick I'm gonna go ahead and stop that we're definitely reaching the thermal throttling stage so let's go ahead and just run a normal run and see what do we get when the system has been in the thermal throttle range um let's see what our values are looking like and I'm going to stay focused here on cinematr23 for this just to give us a like a good focused number 29 300 so this is with with looking at cinebench R23 uh the system should be pulling right around 140 Watts uh and we're doing probably around the 3.8 gigahertz on the p-course 3.2 on the e-course like we were doing earlier and so this is the performance that you're getting in this type of a continuous sediment R23 run scenario all right twenty nine thousand one hundred and twenty so right around thirty thousand in the initial runs then it goes down to about 29.1 k for our continuous runs all right let's go ahead I'm just curious does CPU if we do nothing here if we click CPU overclock does this give us any gains in performance let's let's find out I am skeptical that we will but uh let's see what the CPU does I didn't change anything in the CPU overclock setting so I'm guessing it's not going to do anything at all 4.1 gigahertz on the P core is 3.4 on the e-cores we're hitting the high power boost again because we gave the laptop a moment to breathe and cool down a little bit so 165 watts of power it's going to be right in that you know 29 000 something range again I believe here no real performance gains at this point so excellent let's go ahead and do our established Baseline for time spy with performance mode I have to open Steam up and uh let me get this straight now I've got links in the description to all of the tools that I will be using in today's test so if you need to download any of them please refer to that I've got my laptop spreadsheet right here if you're looking for a top deal on a gaming laptop I would highly recommend checking this out and the legion Pro 7i is currently on this list because it is one of the best bang for the buck laptops out there and it's currently on sale for 21.49 with a 4080 variant which is just an excellent price considering all the premium features this does come with now we're going to be using throttle stop in today's video there's a link to this download page MSI afterburner also linked down below and HW info 64 also linked down below I recommend getting this metal one that's a portable installer this is what I usually use but you can also use the windows installer and it acts more like a Windows application whereas this I have to actually click on the file to open it which is just easier not to have to install it every time I go to a new laptop but yeah it doesn't matter that much really it all functions still the same okay so here we are we've got uh we've got time spy let's go ahead and run time spy again so this is laptops in performance mode no overclock applied let's see what we get um all right and let me well this is running let's take a look at chat all right the 4070 Pro 7i makes zero sense when the pro 5i has the 13700 HX 470 QHD for 15.99 um yeah I'm not sure about the prices between the two I haven't compared the 470 variants the CPU can definitely do around 190 Watts King Dragon how do you get it to pull the 190 Watts because I I've yet to see it actually try to pull that much wattage at least when doing cinematr23 the most I've seen is 165. um demon salad said just curious why not Intel XTU well I wanted to use throttle stop to give I have to use Intel XTU on several of my previous live streams and uh I wanted to give throttle stop an example you start off as an example for people and I do know throttle stop works right so um so there's that now oh looks like we need to cancel this I've got my default over I I've got my I have so my my system booted up with my MSI afterburner overclock I was like those clock speeds are way too high uh those are not stock clock speeds okay so gotta restart it here um because I had my I had my After Burner overclock that I was messing around with yesterday already on that run um so let's see what the stock clocks and wattage and temperatures are here King Dragon says you have to enable custom mode and change the TDP well I was in custom mode with the TDP maxed so I don't I didn't see it pull that but we'll try it maybe maybe I missed that setting in custom mode or something I will I'll try doing that here what's up killer skulls um all right 12 Eric says I was just looking at my I9 it's the same one but mine's only pulling 120 watts with overclocking the same as you're doing running a 470 on a sager um undervolting and overclocking your system would definitely result in a lot more performance toughrick um yeah okay so looking at our temperatures our temps initial temps are pretty good we're pulling 66 72 Watts so 60 to 70 Watts on the CPU 173 174.5 so basically 175 175 watts to the GPU only 2025 19.99 so right around the 2000 Mark for our GPU core clock our memory clock is at 9001. so those are the stock out of the box GPU clocks you can expect on the RTX 4090 and there's a lot of code cores on this guy uh so even at these lower clock speeds you're still getting very good all-around performance um so yeah uh effort to Grass says is there a way to set Power limits in a desktop PC yes you can use if you're using Intel you can use Intel xdu or I believe throttle stop probably work for desktop CPUs as well um I'd have to actually double check that but usually you just use Intel XTU probably if you're using a desktop and an unlocked desktop cord CPU it has to be an unlocked it has to be an unlocked desktop CPU in order to do undervolting or overclocking typically you don't need to worry about under vaulting with desktop CPUs because they have beefier coolers and typically you're primarily just overclocking the CPU because you can jam two or three times more wattage through a desktop CPU than you can a laptop CPU so you're not really worried about power efficiency as much when it comes to desktop technology you're primarily just trying to just slam the highest clock speed with the most power limits that your cooler can handle and keep at reasonable temperatures um okay so evaluation again 80 we've broken the 81 degree Mark 82 degrees on that CPU 75 degrees on the GPU again the GPU boost is around 2000 a little less a little bit more 2100 now so it does boost up into the 2100 range but most of the time it seems like we're doing around the 2000 mark it went down as low as 1950 there um 85 degrees on that CPU right there so this is in performance mode this is not Max fans mode we are not um there's no under multiply there's no overclock applied these are all stock settings right now getting our Baseline established for performance levels on what you should expect all right a hundred 93 degrees on that g on that CPU uh Africa the five dollar Super Chat uh thanks my desktop starts at 240 FPS but by the end of the game it's at 170 FPS my temps are really good gotcha well it might just be the initial boost period and then it goes down okay so we managed 21 965 for our out of the box um Graphics score 15 000 849 for our CPU score um and this is in performance mode if we did balance mode it'd probably be a little bit lower on the scores for both the CPU and the GPU Okay so if you do want just a basic GPU overclock you don't want to mess with anything else you don't want to download anything else you and same for the CPU you can do CPU undervolting right here um but you'll need to enable this in the bios so I think bios is our next stop for this optimization Adventure but you can see you can you can under volt up to 160 millivolts here and same for the e-cores as well though I don't I think the e-course will probably be unstable at that high of an under volt hard to say okay and you also can potentially overclock CPU performance here and there a little bit but most likely I'm not seeing I doubt you're going to see any performance gains here because it's saying to Target 4.9 or maybe 4.8 here um gigahertz for our P core all core clocks and that's just not we're not even hitting that we're only at 4.1 when we're at 165 Watts so yeah and we're only 3.4 and not 30 uh 3.9 on the e-course so we're not even hitting our tops we're not going to save our settings there but in order to get this CPU overclock option to even pop up uh we go into the BIOS I'm not recommending to use this CPU overclock option um because you don't get all of the full functionality like being able to undervolt your cache but it it is nice that it's integrated directly into the primary application so it's in some senses more simple the GPU overclock is also optioned inside of the Vantage software here and you can do up to 200 megahertz on your GPU clock and 400 megahertz on your memory overclock your vram okay so the thing is uh vram in this generation can be overclocked more than 400 and almost all the RTX 49s will probably be able to overclock 200 um but this one for example appears to be stable at 240 at least I haven't I have not pushed it to the max limit yet either which I was going to do in today's live stream with you guys so um we'll have to see what what kind of Max limits we can we reach with this but um but yeah all right so let's go into the BIOS now and well I guess you know what before we do that I also want to mention custom mode custom mode so there's four different modes quiet mode Really Gonna hamper your performance balance mode it's going to give you a decent performance and then performance mode gives you Optimal Performance basically just ramping the fans pretty heavily but not quite Max fans under custom mode you can adjust the performance level and inside of here you can set up to 160 Watts for the PL one and you can do long-term cross-loading 110 you say the CPU Max temperature you say you want to do 99 as your throttle temperature long-term power limits 140 CPU short-term power limits 190. and uh the important thing you need to make sure for gaming is that you need this total processor power Target to be as high as possible here otherwise your GPU will not do the dynamic boost okay so if you're trying to use uh like if you have this set to 50 Watts or 45 watts and your CPU is using more than 45 Watts the GPU will not boost more than 150 total or whatever your power limit you set here for your GPU so this is your base GPU boost wattage and this is your Dynamic boost which will only apply when the CPU is pulling less wattage than what's in this bar so if we set this to 110 the CPU can pull up to 100 watts of power or up to 109 watts of power and the GPU should also still hit 175 Watts that's the way to read this um and just by setting this custom mode without undervolting this is this is essentially like overclocking but without any undervolting being applied we'll go ahead and save these settings the other thing you need to know about custom mode is that you can set a custom fan profile curve based on temperature so you could say like oh when it gets to 60 temperatures I want Max fans and we're going to ramp up this much so that way there's at least some fans going at all times and this would very quickly get you to 100 fan speed the other option is you can just run it in full speed full speed will just give you Max fans all the time which I would not recommend all the time doing I would probably recommend doing a custom curve but for today's testing we will be doing full Max fans all right um now real quick I just want to see if Cinemax R23 is going to run at more than 165 Watts based on what uh let's see here based on what's his name was it someone suggested it that custom mode will let it go past to a higher wattage I don't I did not see this in past testing so let's see if that's the case or not 165 Watts still not going Beyond 165 Watts here with custom mode enabled though our temps are better our temps are quite good um jumping up to our core clocks 4.1 gigahertz 3.4 gigahertz so going into custom mode is not going to give you any more CPU performance uh it's just going to give you better temperatures because of increased fan speed that's pretty much all that's going to give you so let's go ahead and go into our bios and see what we can change in there uh let's see here yeah King Dragon is the one that was saying custom mode to change the TDP but it didn't do anything for us um ZL Thomas says Legion is going to definitely be my next gaming laptop I think it could be a very good choice depending on the pricing and everything um but in general I think it's a good choice okay so in order for us to get into the BIOS we're gonna press the power button and then we're going to tap F2 over and over look how bright that backlight is I love it um we're going to tap F2 over and over and there we're in the Bios okay one more once we're in the Bios we'll want to go to more settings here in the bottom right and once we get in here we'll go to configuration on the left and we'll want to scroll down there's a lot of different settings inside of here but uh here's the restore default overclocking option if you need to revert all your overclocks you can do that um instant boot uh let's hear where is it so you can disable your e-cores there at with active atom course that's your e-course you can disable them if you want um okay so Legion optimization you want to enable this this is going to enable CPU overclocking feature and you want to disable undervolt protection this is going to let you use throttle stop so this is going to enable the overclocking inside of the Vantage software if you want to take advantage of that the undervault protection will let you do apply under volts though you'll need that to use throttle stop GPU overclocking you're going to want to enable that if you want to be able to get the most performance and then performance mode setting is set to extreme um the that's what I have set to I don't know how much of a difference that actually makes system Peak power you can um control the system Peak power to extend battery life I guess that's too for battery mode you don't have to worry about that for performance optimization but uh yeah those are the those are the key things that I change to enable all of the undervolting and capabilities that this laptop has so we're going to go ahead and save changes and exit now so that's just F10 and hit yes my CPU is unstable at Cash 80 core 140 now 125 just down to 130. oh interesting uh igpu undervault doesn't help much yeah it does not help much I wouldn't necessarily worry about um I would not necessarily worry about doing the igpu undervolts really it's the e-course P cores and cash that you'll want to primarily focus on Okay so next up we're going to go download throttle stop all right so they'll go download throttle if you want to do this download throttle stop if you want to use throttle stop or you can use the Vantage CPU under volting functionality that doesn't quite get you everything but gets you close all right so uh and while you're downloading stuff just click the links on the afterburner and HW info as well um so you have those already pre-downloaded all right so I have throttle stops set up to automatically launch when I open a turn on my laptop so you can see it's right here open the the green t indicating that it is active and uh so under the options section here you'll want to have an AC profile set and a battery profile set usually one is set for AC battery profile set to four you have to enable these check these boxes um and then you'll want to potentially adjust your undervolt if you're unstable all right if you're unstable with battery mode versus plugged in mode you'll want to have a battery under volt that is stable so um and when I I have not done detailed battery testing here but just know that you may need to do that if if you run into instability when unplugging your laptop and to be able to adjust these these undervolt settings you click Fiverr here I'm going to zoom in so you can see a little better you go to Fiverr this opens up our primary window for changing settings and our six different under volts are right here these little options at the top under fiber control are per are are four different modes that we can set up as performance game internet and Battery generally speaking you only really need one mode unless you run in stability when you're on battery life and then you'll want to have a battery version as well and under battery my recommendation is just to make your undervolt a little bit less aggressive if you have instability issues so I set my battery under volt to only be minus 100 the cache I did not add an under volts to that but I was just messing with these settings to see if they change when I unplug the laptop and they do indeed change when you unplug the laptop if you have this set up under two different profiles and I'm not saying you necessarily have to do that but you you will want to uh to do that now an important thing you may need to do that is what I'm saying if you run into instability when you unplug the laptop now under save voltage changes in the bottom right here you have do not save voltage changes is your default okay so this means that you can play around this is what you should have selected when you're not sure that you are stable or not especially for booting up if you're trying to go super aggressive with your undervolt you do not want to have save voltage after throttle stop exits or Stables immediately maybe say voltages after throttle stop exits is okay but generally do not save voltages means that when you close throttle stop you're not gonna and you like restart your machine you won't be undervolted okay you won't be permanently your your your undervolts will not be permanently applied if you do save voltages after throttle stops excellent obviously need to exit throttle stop and then their voltage will be saved permanently or say voltages immediately means that it's gonna those voltages will always be active whenever your specific profile up here is selected and uh and this can be a two-edged sword for example if you if you hit save voltage immediately and your system immediately crashes when you reboot and your throttle stop is auto starting you may run into instability before you can get back into throttle stop and disable it so that's the main downside there you have to enter safe mode in Windows to prevent the startup from happening for throttle stop to turn it off or you could disable or you could go into the BIOS and disable undervolting as well to be able to change your throttle stop settings that'd be another option um okay so essentially my recommendation for the saves is say do not save changes until you find an honorable that you've found to be effective and stable that you want to use as soon as you find that undervault then you can hit save changes immediately and then your undervolt will be active as soon as throttle stop opens up again otherwise you'll have to reset your underfold every time you open throttle stop okay so um so let's click ok for that and let's talk about setting up throttle stop for um your your initial launch okay so you're going to want to go to the start menu here you'll want to do task scheduler and you're going to need to create a new task so you're going to create task you can name this uh TS launch you know throttle stop launch that's fine um triggers you're going to add a new trigger to this it's going to be uh on at login of any user or if it's only for you using the laptop you can do that too but any user login and then the actions will be start a program and you're just going to go to the throttle stop folder wherever that is and you'll want to not move that throttle stop folder otherwise it'll the scheduler will break obviously and you just click throttle stop as the program click OK and now whenever whenever you uh start the machine throttle stop will automatically open I'm not going to go ahead and save that because I've already created that task inside of the task scheduler so throttle stop automatically opens because of the task scheduler that I've already set up now um let me check chat uh does it automatically switch to battery mode or do you have to manually do it when you unplug no so if you if you go into your throttle stop options in here and you have AC profile selected and Battery profile selected um whenever I unplug all right whenever I unplug throttle stop will automatically switch two batteries the battery is already activated all right and so that means that my under volts already switched to this under volt which is a less aggressive under volt the moment I unplugged uh and then I plug it back in all right now we're back in performance and now we have a more aggressive I just plugged it back in so now we have a more aggressive under volt back to being active again so um as long as you have those settings set up in throttle stop you can have it auto switch between the different undervolts and have throttle stop automatically start up it's a pretty easy application to use once you get the hang of it um all right so let us move on to our next step for today um we're going to set up the laptop cooler all right so this is the is GT500 laptop cooler we're gonna use this to help reduce our temps um you know it's I don't think I I do not think that the uh Legion Pro 7i really needs it this is a laptop that has good temps out the box but we're gonna see today how much this cooler can Aid the legion Pro 7i you know we were hitting over 90 degrees in the Cinemax R23 and even in time spy we were hitting 85 degrees on the CPU and like high 70s with the GPU so and that was just in performance mode all right and now I'm going to plug this in all right so the is GT500 um I do not have a link in the description right now but I will try to add one um so this cooler was the best cooler that I tested out of a batch of coolers that I bought and uh this cooler is really nice in a lot of ways because it has uh it has an air filter which helps prevent any additional dust from getting in your laptop it's got a like suction style or a air blowing like it sucks air in from the back and kind of pushes it up into the bottom intakes of your laptop um and because the air is filtered like I said it should help reduce them out of dust that goes in your machine and your fans I love that okay so uh the laptop cooler is set up now you can see I'm going to turn it on so you get additional RGB around your laptop with the cooler and you can hear that it's a very loud cooler that's the main downside to it in my opinion all right and uh so not saying you have to get a laptop cooler for this laptop I don't think it really needs it necessarily but we're doing it to maximize possible performance and and all of that right so yeah toprix has so much RGB right I mean it's so much RGB now okay um no fortnite today nope uh all right uh well so the you should test it with just an undervolt without cooler well undervolting is not going to really affect our temperatures undervolting it is primarily going to affect our performance because our temps were we were not thermal throttling before anyway all right so um we're gonna get cinematch R23 open we're going to get HW info 64 open all right and we're going to go into the Lenovo Vantage software we're going to set it to custom mode okay and under custom mode under custom mode we're just going to set everything to Max basically all the settings are set to Max the one thing I would say it might be a good idea is the cross load set this to 109 so that way your GPU never down clocks to 150 okay and we have full fan speeds going right now on both the CPU uh sorry both the legion fan and the GT500 cooler is going at Max right now all right so now let's go ahead and we should verify as well that our undervolts are being applied our offsets are here you can see the offset minus 160 millivolts minus 125 for the ring and then our L2 is -100 those are the three this is the cache the ring is the cash um and those are the three most important ones all right let's go ahead and let's go ahead and run it and see what we get let's check out our clock speeds so we were doing 4.1 gigahertz before we're now doing 4.6 on our P cores that is huge 500 megahertz increase 3.7 gigahertz on our e-course um from up from 3.4 so 300 megahertz on our e-course 500 megahertz on our P cores and look at our score 32 500. that's without focusing on cinebench R23 that's what looking at HW info let's do one we're just looking at cinebench R23 while this runs thirty three thousand twenty two all right so we've increased our performance on our CPU by 10 percent that that to me is phenomenal undervolting value right there uh because basically our best score was just broke 30k right around 29.9 K often and now we're doing over 33 000. so we got 32 800 there let's take a look at our clock speeds again 4.6 gigahertz 3.7 on the Ecorse 3.6 to 3.7 on the e-course looking down at our temps right now we're only doing 69 on the cores 74 for the package and the highest temp we've recorded so far is only 76 degrees on the CPU so let's go ahead and let's go into a 10 minute test just to get a continuous load so we can get our thermals basically and our power limits uh an idea of our power limits and thermals and I'll reset our numbers as well so it's pulling these 4.6 gigahertz 4.5 gigahertz 3.6 3.7 gigahertz on only 152 watts of power so we're pulling less wattage and having higher clock speeds at the same time of course pulling less wattage that's also going to help translate to lower temperatures as well so only 77 degrees on the package 71 on the course right now with the peak temp for the package being 77 degrees while pulling all of this juice through the CPU that is really great Temps like just it's just phenomenal I have not seen any coil wine on this laptop foreign it's hard to know how much the underbolt is affecting the temps because of the cooler zinc I hear you I hear you but we're just I can't I can't test every little iteration as you know in detail without slowing this process down a little too much um but generally speaking undervolting usually does not in decrease temps uh much usually it just provides more performance at the same temps that's my current belief about undervolting sometimes in games it may it may reduce your temps by a little bit because the game may only need so much CPU and if it can be do if it can be more power efficient then maybe the temp inside of a game will be lower but inside of a all core turbo boost to the max scenario like cinebench R23 um the temp drop right now that we're seeing is primarily due to running fans at Max Speed on the laptop and adding the laptop cooler because you know we were doing uh 140 something Watts before and our temps were hitting 90 91 degrees for our Max temps looks like we've brushed into 79 degree territory as our Max temp and I don't I don't think that it's going to get any hotter than this so we've effectively dropped the CPU temp by 12 degrees by adding Max fans and the laptop cooler while at the same time increasing our performance in cinema R23 by 10 percent um do fans need to be on Max to get close to this performance or will it overheat if they aren't it's going to depend on your room and ambient temperatures and all of that but if you did not have Max fans and you did not have a laptop cooler then you're probably still just going to get around the 90 degree Mark in this test just like we had before undervolting but you'll get higher performance you'll get the you'll get the increased performance with or without the laptop cooler and Max fans the the under volt is what provides the increased performance the max fans and laptop cooler is what provides our drop in Temps thank you at the same clocks undervolting drastically lowers the temps that's correct uh slick rounder but we're not at the same clock so we've increased our clock speed pulling the same amount of wattage so because the wattage is the same when you under bolt or don't under volt that's why the temps will be the same in this type of scenario it just depends on the scenario whether undervolting would actually improve your your attempts or not um the tip like in cinematr23 I would typically not expect the temps to drop if the same wattage is being pulled if it's a reduced amount of wattage then yeah I would say that is likely to be true okay so we're going to do another test this is going to be like um our long power limit basically type of a test we got 29k before the undervolt let's see what we get uh now that we have the undervolts applied 32 700. so that's three thousand seven hundred Point increase in our long power limit performance and let's do it one more time just to verify the result that is excellent a phenomenal performance game thirty two thousand three hundred let's do it one more time now keep in mind that these are not the the best undervolting uh necessarily the best undervolting performance you'll see on an I9 3900hx processor I have seen some users pull higher wattages and also higher performance levels 32 900 so if we were to average those three together we'd be getting right around thirty two thousand say 650 there's a crash right there so that means that we have our undervolt over tuned a bit there's the first crash I've had at those wattage levels at those under volt levels and this is part this is this is what you expect to happen when you're doing under voltage so um if this happens I'd recommend uh dropping your undervolt back say 10 or so foreign so let's try to keep Chad civil I see you guys kind of arguing about the 40 70 a little bit but yeah the 470 my take on the 4070 is that it's not worth it if you're paying a premium price for it but if you get it at the right price it's a great GPU um though the vram is certainly limiting depending on the game you're playing okay so if we're to adjust our undervolt settings go to Fiverr and opening throttle stop here we're going to go ahead and drop this down to uh say 150 for RP this is our most aggressive undervolt so this is the one I'm gonna adjust it might be some other undervolt that's causing this but we're just gonna do 150 for our P cores and we're going ahead go ahead and save those settings so we've reduced our undervolt by 10 millivolts if we crash again we'll know to continue reducing our under volts by an intervals of 10. uh basically is what I do if you want to ensure stability more quickly you can do intervals of 20. and once you've found stability you can increase it back until you find the right level Okay so we have downloaded installed throttle stops we've configured throttle stop uh we've done cinematr23 let's go ahead and do our calculations for how much improvement in long-term power limits we had we had 29 000 100 before our long-term power limit performance versus long-term power level performance we had a gain of three thousand six hundred and we're going to divide that by 29 100. we had a 12.4 percent performance gain overall from undervolting the I9 processor and like I said this isn't necessarily the maximal undervolt we did run into instability but there might be other aspects like maybe we could increase the e-core under volt further or maybe the cash underwolt further um because we may not be maxed on all three of the relevant undervolt scenarios okay so now we're going to go ahead and do undervolting the RTX 4090 for best thermals and best overall performance so we're not going to do detailed thermal undervolt I'm going to give you the the quick and dirty undervolt instructions for undervolting but we will try to do a little more detailed on the max performance because I think that's primarily going to be most people's interest with this laptop so this is afterburner I'm just going to go ahead and make this really big so people can see it better all right so MSI afterburner this is the default skin you can change the Skins to different things the way we're going to be undervolting uh is going to be different than when we do Max Max performance overclocking today if you want to undervolt for the most performance the first step is get 3D Mark time spy running and you'll want to run it in a loop or you can run Heaven Benchmark or whatever you want um but we're going to do it in a windowed mode we're going to Loop it and we're gonna do Graphics test two we're gonna run this in the background what this is going to do is it's going to set our GPU to basically highest possible performance mode all right and it's going to give us realistic feedback for whether our overclock is stable or not at least initially now not every game engine is going to perform exactly the same as 3D marks so you may run into instability and issues uh depending on the game and you may still need to make future adjustments I just want to add the frame time graph in here as well okay so let's talk afterburner basic overclocking is just change change this core clock up and down to overclock and under volts if you were to under volt it you could just like minus this down right uh this is not what you want to do but I'm just saying like this is one way you could undervolt your system uh you apply this it's going to reduce your core clocks here which is just not going to be very good for your performance level okay so not recommended to do this instead what I recommend doing if you're trying to under volt your system go to the curve editor this curve editor see this line going across that shows us what active node is being utilized and when the GPU is in high performance mode you'll be able to see what node range is used for the performance so each node here represents a clock speed on the left that the GPU is hitting and a voltage in millivolts right here so 850 millivolts or 0.85 volts is very common all right so if we go in here if we go focus on this window we can see this in action now I have HW info configured to show me my GPU voltage and I'll show you how to pull this up so you you go down in HW info you click on your core voltage you right click and you click rtss and then you click show value and OSD and show label if you want to have the label and this is what pops up so you can see that uh right now the GPU is pulling 865 millivolts 840. this is all stock no overclock currently being applied and right here you can also see our active voltage at the same time 885 850 so we're seeing a range of 840 to 875 is very common and in afterburner if we click the curve we can see that range being hit right here so if I click on one of these nodes you can see that's 845 right there that's the 845 node and if I T if I press tab I can move down the list of nodes here this is the 875 node this is the 840 node and so when you're trying to overclock your system um when you use this when you use the curve editor um you can adjust each node individually versus when you do this core clock slider you're just raising all of the curve the whole curve is going up and that's the thing about this GPU I believe we just crashed uh that's the thing about this GPU um so we probably just crashed because of the undervolt because I did not apply that overclock that overclock was not active going up and down um so the the what am I trying to say so right there that indicates that we need to lower our undervolt further on this I9 chip yeah no again this is expected if you're going to mess with your system like this you got to expect to see uh regular crashes like this until you get all your settings dialed in and then you should not see any further crashes so I'm gonna go ahead and lower my over my undervolt on all my stuff by 10. the igpu is probably on unnecessary but I'm just going to go ahead and do it all just in case it's maybe the e-course that are causing us to crash or something else all right so our undervault just got a little bit less aggressive so what I was explaining about the curve editor is that uh essentially when you're trying to optimize for most possible uh best possible thermals what you want to do is Target a low end on your curve a little bit below the wattage that your GPU normally pulls so we saw endearing Max performance mode we saw that we were hitting in the 840 range a lot and that gives us right around a 2000 boost clock so what we would want to do is prevent the GPU from you going to the full wattage and we will instead want to go a few nodes down say five or six nodes let's go to the 800 node here and what we'd want to do is just raise our boost clock up to that default around 2 000 or maybe like right now I would probably add Plus 200. basically two the the curve there and then we'll apply that and that that flattens our curve right around that area and now we also want to click that node all right and we want to press Ctrl L that'll lock our voltage to that lower voltage range and help prevent the GPU from pulling any additional power which what that does is basically gives us better thermals and we're going to get the same performance you would get out of the box um for the GPU yeah Caitlyn you went with a very uh a less aggressive under volt minus 111 millivolts and minus 94 on the e-course is not too aggressive probably most i9s are going to be able to do that level of undervolting most i9s will probably be able to do minus 100 on the core cash P cores and ecors so let's get HW info back open again we may need to continue lowering our undervolts if we can keep crashing but this is this is how real testing is done on these things right all right so let's check out our we need to get HW info open there we go I want to see our core voltage interesting our core voltage is pulling okay so what we want that's what we want we want 800. all right and what we want in this type of scenario is for our temps to also be really excellent and what we want is to get a high boost clock on the GPU while reducing our wattage okay so we were basically doing 173 to 175 Watts previously and we're only doing about 2 000 on the GPU boost now you can see that we're occasionally but wow we're occasionally bumping our wattage up and if you look it's because of the curve it's still these some of these are interesting so some of these need to be dropped a little bit because we're occasionally hitting them some of these nodes are active and really what we want is the GPU to only hit 800 millivolts here and that's when we're hitting the lower wattage level with the same level of performance honestly this is better performance than out of the box performance because before we were doing around 1990 uh 2000 or so megahertz on the Boost clock now we're doing 2070 which is more well at the same time having less juice going through the GPU so this is an under volt that optimizes our thermals if we want to go to just if our goal is stock levels of performance you know we could try to go even further down the undervolt train say 775 node and let's take this up to the 2000 mark all right let's just take this up to the 2000 Mark which is a plus 215 overclock um also we may let's reset this we may want to go ahead and lower we may want to go ahead and lower our curve down like this so that way our GPU doesn't boost up the way we wanted it or the way it was there we want to keep the GPU to this 775 node so we're going to set it to 2000 just like that to be able to do this you click and hold Ctrl and drag down with your mouse let's go and set see if this is going to be stable for us so you now notice that all of this whole row here got lined up for us so now it's not going to boost our wattage Beyond and let's also go ahead and do control L to lock our voltage to that lower node and now let's see so 775 and we're hitting 19.95 for our GPU boost clock and look at our RTX 4090 wattage 146 now so in our temps are only 61 degrees 69 on the CPU so uh absolutely phenomenal temps remember we were getting up to 85 degrees on the CPU before and our our GPU was doing 75 I believe so we've dropped 15 degrees on the GPU because of the laptop cooler and the GPU undervolt and we've done about minus 15 degrees on the CPU so if you're after the best thermals this is the basically the setup I would recommend and you're gonna like this would be right now what I have here is basically stock performance for the GPU but lower wattage and overclocked an undervolted CPU for optimal GPU performance now let's go ahead and talk maximum possible performance on this system I'm gonna go ahead and reset our curve here so our we have a default curve again notice now we're pulling 175 Watts 2 000 megahertz on the core um all right so let's go ahead and uh let's go ahead and do Star Wars streaming chat um so the so the tricky part I when I was trying to get the GPU to lock to a specific voltage I couldn't get it to do that the V bios one keeps once keeps wanting to jump around the voltage range so like it's jumping around between 835 800 something like that 840 all the way up to like 870 8.80 and because it keeps jumping around even locking the voltage on the Node here didn't do it the way I wanted to like when I was doing the RTX 4060 4070 I was able to select the highest node and the GPU the V bios is always hitting that that node all the time and uh and it wasn't a problem we could we could try to just lock our voltage to that specific voltage node and it would just Peg it at the highest overclock possible you can't do that on the Legion or I was not able to get that going on the legion here so that's the tricky part about this overclock here um I press the button there we go um so that's the tricky part about doing this overclock right now um and that's why currently the best performance that I've been able to get out of the system is just raising the r curve overall uh so that way as it jumps between the different voltage levels um we're getting the best possible boost so that would involve just saying hitting this to let's try 250 I don't know if 250 will be stable or not um and let's do let's just do 400 on our vram all right so we've applied that now and let's see what our voltage is doing so right now it's at 825 core voltage look at that 2400 on the Boost clock for a little bit there 840 840 845 2235 22 20 22 35 22 20. um obviously I believe that you probably could wipe the V bios out and install a different V bios maybe be able to get it to lock to a specific node and and stay there rather than shifting around between these different nodes but right now we're getting into that much higher boost clock range we were again you know around the 2000 boost clock now look at us jumping between 2200 to 2300 um occasionally dipping below that uh 2200 right in the 2175 range but on average I'd say we're averaging around 22 30 to 22.50 depending on what voltage node the GPU jumps to and look at our our CPU is also cranking at 78 watts of power GPU doing 170 3 watts of power and our temps are still great so that is just phenomenal custom mode with Max fans and a laptop cooler really like to keep the CPU and GPU in this performance range well pulling this kind of wattage is very impressive now um we could try messing with locking the voltage and seeing if we can get something to stay stable but I'll show you what I'm talking about while locking the voltage doesn't appear to be working so let's say that we're doing um let's say we were going to try to lock it to 840 because it keeps boosting that low and let's just say we wanted to keep it a stable 2 22.50 all right so I'm going to lower this down as well so we're gonna do 840 and we're going to go up to 22.50 let's see if we're stable trying to do this all right so we're gonna try locking the voltage press Ctrl L to lock the voltage let's see what happens so look at it it keeps dropping now it's 825 voltage 820 and look at our our clock speed right here is only 21.90 now that it's hitting the 840 we're getting the 2250 range but it's not it's not holding steady to that voltage uh and so like I don't know I guess you could try doing the lowest possible node like it was trying to do it under 825 let's try using 825 as our locking voltage node and let's only do 2200 let's see if we can get a stable overclock here so it's staying at 21.90 right now at the 825 voltage and it's not quite staying perfectly stable it is dropping to the 2175 range after locking click apply again that you can't even click apply again it's grayed out nothing has changed so so you notice it even went down to 820 on the voltage here so it keeps jumping down but it's it's staying pretty stable around this this point but the thing is we're not getting maximum performance because we're not pulling the full 175 Watts on the GPU either but we are getting we are overclocked and we are getting slightly lower wattage so this is a pretty good overclock under volt for kind of Optimal Performance range I don't know if it would be stable or not uh but it appears to be in stable in 3D Mark so anyway the best performance that I have been able to see in this system is just to set your overclock we're going to do 21 or we're gonna do 250 with a 500 a 500 memory overclock and this is the highest stable clocks that I've seen on the GPU so far averaging over 2200 sometimes boosting even higher and we'll have to see if this is actually stable because this may not be stable if it ends up pulling a voltage down too far basically that is undervolting the GPU essentially but we're also getting an overclock at the same time so our overclock here is quite nice 2300 on our boost clock is very high for an RTX 4090 over 2200 is high you know like I said the the stock out of the box 4090 does 2 000. so we got over a 10 overclock going right now on this GPU let's go ahead and run time spy and see if it's stable at this plus 250 500 OC and then we'll start doing some game testing and seeing if we're stable at this OC as well what's the limit for under volting and overclocking on this lapping um I mean basically I just showed you the GPU limits uh around 2200 give or take about 50 megahertz is the overclocking limit for at least this 40 90 that I have if we were to push it a little further uh probably 220 uh 270 275 I bet we would crash I think I think I did crash I think we may even crash at plus 250. I'm not sure we'll see here um Matt says thanks for the input LSP I've been researching laptops lately and I want to get one mostly to game on but strongly considering this one for the price to Performance ratio yeah I think it's a great option for people I think in general the legions Pro 7i is is without a doubt one of my top recommended laptops okay so uh let me see here all right so this is our stock oh sorry this is our overclock right here I'm gonna see if I can get the window to pull up to show you guys a side by side with um with the original overclock that the system comes with let me mute that and all right we gotta change our our labels here but uh okay so this is my CPU we're at plus 250 Plus 500. for our OC and uh uh right so this is also uh custom let's go ahead and add this one step down okay so looking at our temps and our performance levels uh let's see I gotta slide this window over just a little bit there we go um and our GPU boost clock look at how much higher our GPU is boosting um you know so the window on the right over here is the Vantage the Vantage CPU uh let's go ahead and go back a little bit there um so that's what the Vantage GPU overclock default being applied 150 plus to the ooc um and let me add that so it's Plus 150 200 um there we go so we'll see if we're stable also in the CPU test notice that we are pulling it seemed like we were pulling just a little bit less wattage there and now we're going to compare our score so Vantage default overclock versus After Burner overclock we managed to get uh uh wow so we managed to get one thousand two hundred and eight additional points over the uh the stock overclock or like the the Vantage GPU overclock with our additional OC here so uh that's quite delicious and I gotta say that overall that's gonna be a nice overall performance game now our CPU score did our CPU score go up at all I don't think our CPU score really went up uh almost at all let me see yeah it actually went down 40 points which is very interesting um are GPU on our underwald should have brought our CPU score up by a little bit and our CPU score currently does not appear to be uh it actually went down just a little bit which is interesting I don't know um okay pretty impressive yeah so 23 200 is excellent uh you know I love to see I think the highest n490s might be able to go closer to um 24 000. by 23 208 is obviously excellent and if we were to compare our performance level let's go ahead and pull up the calculator so twenty three thousand two hundred and eight minus uh what was the stock we had at the beginning of this live stream we did a test I'm pulling it up here so our initial score was twenty one thousand nine sixty five so we gained 12 43 for our overclock um if we divide that by our original score we got 5.6 performance gain all right so that's our that's our initial straight time spy performance gains our CPU performance gain was 12.6 from undervolting our GPU performance gain with time spy 5.6 this is not necessarily the most optimal overclocked yet there may be more overclock room here in the 270 range maybe but it might be unstable hard to say but this I have scored actually 23 400 by the way in a in a test I did yesterday um which is interesting because I actually had a 240 under volt during that test so or sorry 240 overclock during that test so um so yeah so you know your time spy runs will vary a little bit you know we got HW info running in the background and some other stuff so uh but overall really nice performance gate let's go ahead and hop into some games and we're gonna do some split screen game testing to see if we can get any performance gains in the game play the actual gameplay and if we're stable in the actual games because that's very important to do stability testing to actually play your games that you play and check stability in the game titles because this OC might be okay in time spy but moment you get into some games it might crash so yeah I think ours I think our Times by CPU score uh could definitely be higher yesterday when I tested it I got over 16 000 something so I'm not again I'm not sure why it went down a little bit but it is what it is overall we're seeing some nice performance gains so let's go into firing range and uh see what we get I'm not sure if there was an updated firing range yet no it's the old firing range well we're gonna see what we get anyway okay so let me go ahead and go into here let's go to the browser window split and uh okay so keep in mind that the everything that we're gonna be comparing with is basically the Vantage default OC versus our overclock here though I suppose we could we could disable the overclock on the GPU and check performance numbers while staring at the same spot that could work too um if we want some numbers for right now so this window is the active window oh it looks like we already crashed look at the core voltages pulling 940 millivolts which is obviously very high so I'm guessing our GPU crashed we're probably gonna have to turn the system off and on again I don't think this was a CPU crash though it might have been that GPU overclock we got it plus 250 is quite high so I'm guessing we need to lower that down 225 causes problems for you LSP yeah my guess is probably 225 is more realistic for actual in-game testing we'll have to see you may want to turn off system agent undervolt yeah that may be true I agree that that uh it may not be needed at all um and that could be causing instability because that is a very sensitive to undervolting or more sensitive to undervolting so let's just pop into throttle stop and let's go ahead and just set this undervolt back to zero all right for our system agent I don't necessarily like I just tried under bolting everything to see what we could get don't necessarily recommend undervolting that anyway um okay so let's open afterburner up again and HW info and let's get Apex Legends bloated up again Carolyn says that his time spy score and C CPU and performance mode was 18 132. and in custom mode there's only six one thousand or sixteen thousand one seventy interesting um that's I think that custom mode may still provide better performance it's hard to say um let's go to our afterburner and check our overclock so it's still set to Plus 250. let's see if we crash again I think we probably will crash again but let's see if we crash again in the firing range I want to see if the system agent undervolting was the problem or if this is the problem look at our look at our look at 940 millivolts our GPU is not at 100 utilization and we crashed again so yikes so this is definitely I think the reason why like it's boosting so high with our core voltage and our clock speed 25.95 is insane so I'm pretty sure that's the reason that we crashed we crashed it basically the same Point again so let's go ahead and reset this and um you know if we don't want the GPU to boost to that high of a core clock what we can do is flatten our afterburner curve so that uh the nodes passed say 8 50 are flat that way we know that the GPU is not going to try to boost to some insane boost clock like that and cause a crash all right so we're dialing in our overclock we want stability slick around here we already got rid of system agent undervolt There Is No Sa under volt I'm confident that the crash is being caused by trying to overclock so high over here okay so let's let's do a curve under volts uh overclock not I guess not under volt there's a straight overclock we're gonna we're gonna do this first lowering our well I'm pressing Ctrl clicking on a node and dragging it down lowers everything all right and then we want to take uh we want to take the node that we want to really Target say the highest realistic one is probably 8.50 and let's raise this sucker up all right we're going to take this sucker up to 22 Plus 200. plus 220. let's try plus 220 for our overclock so that's 220 over the standard voltage curve and what this is going to do is it's going to flatten all of these nodes that were to the right and it's going to give us a gradual increase so we will drop clocks if our voltage can't maintain but we won't go above 2300 for our boost clock on the GPU anymore I think this is going to provide nice stability we're also going to lower our memory overclock let's do 400. let's try hopping back in would Windows key plus control shift B rescue a car graphics card crash uh Frasier it might might not I'm not sure I've not tried using that Windows key plus control shift B it might worth trying if it happens again here and uh if we keep crashing even without a GPU overclock that like uh then we know that it's the CPU undervolt that's causing the issue too so you know let's let's go ahead and save this to number two slot here but then let's revert we're gonna go to default We're Not Gonna overclock the GPU we're just going to validate our overclock under volt for the CPU first because we want to make sure that the CPU is stable let's isolate our issues first if we're stable inside the firing range now we'll know look at that 900 940 millivolts is what the GPU wants to pull or that's the voltage nodes using 23.55 is our stock but we're not GPU bound so I think this is the reason why we were crashing before so let's go ahead and try applying our number two which is our flat our Flat Line overclock let's see if we crash now all right so now we're at 8.50 our our boost clock is 22.80 our wattage also dropped from 150 to 125 which is nice which is going to give us cooler temps look at our temps 53 degrees Jiminy Christmas that is such good Temps um and of course we're we are being uh we're being frame capped right now we're hitting Max frames at 300. that's why we're not being 100 GPU utilization all right so looking at so basically right now what we've got going on is an undervolt because we were doing 940. stock voltage is 940. we've got an undervolt and an overclock being applied this is giving us Max GPU performance reducing our wattage pull giving us lower temperatures at the same time and uh if I go to our browser split here let me go ahead and update these settings now so we've got a plus 220 curve uh 850 millivolt under volt on the GPU right now with a 400 400 memory overclock and uh so this is this is what we were doing before all right so this is what uh this is what the GPU is doing before on the old aiming map so that's the key thing to keep in mind all right looking at our our one percent lows and overall FPS it's very similar in the close to 300s basically Max FPS very good uh overall experience for gaming in this uh the big thing here looking at are boost clocks we're actually our boost clocks are in a pretty similar range you know like if I were to pause this it boosts around between 2100 and 50 to 23.50 for our boost clocks um our CPU is about the same wattage but look at our look at our CPU clock speed 4.9 to 5 gigahertz on the new one over here with the under volts being applied to the CPU and look at our CPU clock speed here 4.4 so our CPU undervolt is really amping our uh CPU clock speed in game which is great and looking at our Temps with the max fans with Max fans and the laptop cooler enabled our CPU temp has dropped about 13 degrees our GPU temp has dropped 12 degrees so that's phenomenal like super phenomenal actually really big GPU drops and the performance is basically identical between the two scenarios because we are frame capped hitting easily 300 FPS all right let's move into our next game uh war zone two this is going to be interesting because Warzone 2 has gone through so many changes honestly I don't even know if war zone 2 is going to be worth uh looking at because of so many changes but we can try it thank you um what the Windows key yeah okay never mind yeah slick rounder you're basically saying to do the same things I'm saying um I I think I think Warzone 2 performance if we had the undervault enabled versus no wonder volts enabled which we can do that we could do that with just the CPU going to throttle stop enable it disable it um you know do that whole Shenanigans and I think what we'll see is uh a slight uptick in performance because of the increased CPU core clocks but let's see so we got to reset this war zone 2 is doing the whole uh initial setup phase here for some reason probably because of some big update still traumatized with Warzone 2 after the tough laptop stream yeah that was really bad performance for some reason yeah and Warzone 2 was also messed up in the blade the blade 14. live stream I think too this this x-rite application keeps popping up and messing with our window Focus wow they're not going to let me skip this intro guys we have to watch this whole video this is ridiculous come on look at their CPU why just pull in 127 watts to watch a intro cinematic movie my guess is it's actually prepping the shaders in the background optimizing shaders we need to change the resolution because everything became huge what's up Asus Jesus I'm John welcome welcome so to test this I think what we're going to do is we are going to go to a region hopefully a common region we'll do like a run down the street and then I'll go disable my under volt and then we'll run down the street again and see if there's any Improvement to the FPS I don't think there will be but there might be uh well well maybe they're yeah I think there might be like a three to five percent Improvement you know Apex Legends we didn't see an improvement to Performance because we were already at Max um we were already at Max performance already at 300 FPS but we saw a massive reduction in Temps uh uh it does not matter can I just okay our shaders optimizations at 19 percent up here in the top left uh we could let that finish it kind of goes pretty fast once it gets past like the initial like 20 40 percent um what's up Aviation uh Leon Stevens says also I put two letter size envelopes covering the front half of my cooler so all of the air goes to the laptop two letter sized envelopes covering the front half of my cooler interesting okay so uh let's see if we can go in here and change our resolution screen refresh rate we want at 240 as well okay so we're at 240 refresh rate we want to go to minimum spec dlss on quality there we go very nice now uh that should be good looks like our shaders are done up there in the top left can we go they changed they changed it again battle man they changed the menus again in warzone some of the like least user-friendly menus of any game I have ever seen in existence and then the fact that they like add and remove game mode so you're like let's go do solos and then sometimes solos are just not available to you and play um uh Aviation just joined the stream so it's just optimization for the legion correct so what we've got today is the optimization for the legion Pro 7i with the I9 13900hx and the RTX 4090 so those are the two things we're trying to optimize in today's live stream and uh we're gonna see what kind of performance we can get on low settings and uh I will see I don't know right now we're only doing 109 FPS seems a bit low I mean Wars like so Warzone 2 is broken they've done patches on it they've completely changed performance levels so to test this what we're going to do is we're going to activate uh uh I guess we should probably do um no under volt first and then do an undervolt all right so right now we should have no undervolt being applied let's make sure that's the case no under volts are applied right now you can see that uh let's go back into war zone so I9 we have an overclock on the GPU all right let's do no overclock on the GPU either so we're stock we're stock on the GPU we're stock on the CPU we're double stock and then we'll try applying the CPU and GPU over clocks under volts interestingly enough um I think we may see higher GPU boost clocks out of the box here all right so 130 FPS right in this range right in this area finish land a hit all right so we're gonna need to uh hey we can actually use our traditional we can use our traditional testing site area yay that's nice why am I using MSI tweaking software for a legion because the MSI afterburner is a way to modify your GPU boost clocks beyond what the Lenovo Vantage software will let you do Lenovo Vantage software will only let you overclock to 200 400 on your GPU boost and then there is no curve editing allowed on that overclocking so because we're using the curve editor I think we can get better overclocks and better overall performance levels comparatively when it's all optimized correctly yeah I use the same MSI afterburner on all of my laptops uh just because it seems to be the best the best software with usually up-to-date performance metrics and this overlay is also part of the MSI afterburner plus Riva tuner statistics server okay so this is going to be our stock run 130 FPS 132 our GPU boost clock we're not GPU bound we're CPU bound right now we're doing 102 watts to that CPU 4.8 gigahertz 5.1 4.8 132.83 for our our actual performance number all right let's go ahead we're gonna run back over here hopefully no one kills us so we don't have to reset uh we'll lay down we're gonna do another test here so we're going to apply GPU overclock profile 2 which is our curve overclock which has the flat curve and then in throttle stop we're going to switch to our performance under volts all right so we have our undervolts applied we are undervolted and overclocked now let's go ahead and see what our FPS is like now 140. and higher one percent lows at 86 right now so that gave us a approximately 9 FPS gain in uh about a nine FPS gain for our average and our one percent lows was just like a few FPS but that's a nice quick overclock gain right uh right here we're doing 141. let's just let's see if we uh take our overclock disable our GPU overclock does our GPU overclock wow our GPU overclock didn't really affect things very much we're actually getting slightly higher FPS now because it's gonna it's let we're letting the GPU voltage ran run run and we're getting higher clock speeds slightly so 2340 on our GPU core clock if I switch it back I think we're gonna what we're gonna see is a slight reduction in performance again now okay so so yeah our our clocks our GPU is basically making no difference so right now our GPU makes no difference here our CPU is the one that matters look at our wattage pull only 86 Watts right now on our GPU or sorry our CPU we were doing a hundred and something Watts before we undervolt it so right now we're doing 85 right looking over here 89 86 let's open throttle stop up again let's remove our undervolt look at that we jumped from 85 approximate Watts now to over 103 Watts on that CPU so by undervolting inside of a game we're seeing massive wattage reduction which is going to reduce our temperatures from undervolting while at the same time giving us about the same levels of performance in this scenario so this is different than cinebench R23 under volting inside of a game giving us reduced wattage pull well potentially also increasing our FPS um so right now we're doing 72 degrees on that CPU 70 68 72 so let's say around 70 to 72 uh for our Temps let's apply the under volt back again all right and now we're only doing 84 Watts similar clock speed on the CPU but look at our temps our temps are coming down quickly a five degree drop in about 15 seconds it'll probably keep going even a little further very impressive all right so that's that is just wonderful to see really helps you optimize your system for better Temps while at the same time providing basically identical performance if not a slightly better performance right we had a we had a 10 FPS gain actually right on applying the the GPU overclock CPU under volt uh uh right so it's it's pretty nice uh I think I think a lot of people are really going to appreciate this kind of uh overclock undervolt on their system uh for their day-to-day gaming you know and if you have these uh even if you don't run Max fans like right now we're running Max fans with a laptop cooler it's still going to help reduce your temps all right very nice okay I think that gives a good a good example to Warzone uh a good a great example of war zone difference in performance uh so let's move on to Counter-Strike and uh let's see here well this is kind of is Counter-Strike our next one let's see yeah Counter-Strike CS go so I'm not sure how much performance gain we're gonna see in Counter-Strike let's find out what happens if you turn off the cooler well you would need to take it off of the cooling stand because it's like air sealed around the cooler and sucking air into the cooler so if you turn off the cooler you have to take the laptop off of it and set it on the table otherwise you know you're not going to get there's like it cuts off the airflow um lower temps equals less throttling Frazier that is going to only be true if you were thermal throttling to begin with if you were power limit throttling um or just hitting Max boost clocks like in that scenario we were just hitting Max boost clocks regardless um you know so when we undervolted our CPU was able to go to a slightly higher clock speed but in either scenario we were not thermal throttling so uh if you're not thermal throttling reducing temps is not going to improve any kind of performance or anything so uh we've got the side by side for this one let me go ahead and try to pull that up I'm not sure how much of a performance gain we're gonna see here all right so getting the test ready here let's go ahead and split this I'm gonna need to move this up over and I'm gonna need to slide the camera to the right a little bit there we go Okay so that should be good so the key number we're looking at is the FPS counter in the bottom right very similar levels of FPS this kind of performance gain is might be really hard to notice um so right now we have plus 2220 curve but if like running stock GPU voltages Maybe well I think our FPS number is jumping a little higher I think it's so hard to read it like right now we're jumping between 600 700 but so is the other one let's see what we get in Smoke down to the 90s down to the night like I don't know it's so hard to tell we'll have to see our average at the end of the test to see if we see any performance gains you know and in this scenario we may not see much performance gain because we're using that curve and because we're not letting the GPU go to that Max potential voltage of 940 millivolts so in certain games we may see a a degradation in performance given our curve that we have set up right now because we're not using the offset curve and this last and the original test over here on the left had 150 overclock offset that let it go to as high of millivolts as possible all right so let's see what we get so the original test got 524 and R over clock under Vault result 544 so we got 20 FPS gain for free woohoo um of course Very CPU bound game uh uh or GPU bound depending on the situation inside of smoke very CPU bound inside outside of smoke generally more GPU bound so we have 20 FPS gain at no cost it's nice to see that we are getting a gain instead of a con you know like I love to see that we're getting a gain 524 versus 544 that's a nice nice little gain there okay so let's move on to our next test uh let's go to God of War now this one should be a very good test because it's uh tends to be a very GPU bound game very GPU focused test um so I'm anticipating some nice gains in this one we'll find out here very shortly does the ambient temperature make much of a difference uh yes it can if if you are close to Thermal throttling let's say that you're 90 degrees on your CPU 90 degree or 85 degrees on your GPU you're not thermal throttling you're not reducing your performance but then you go to a room that's five degrees hotter or let's say you go outside and it's 10 degrees hotter you're probably going to see thermal throttling because you were close to it already in a cooler environment so ambient Ambient temperature can make a difference all right let's just double check our settings 2560 by 1600 dlss on quality Graphics are set to Ultra let's go ahead and continue all right so uh this should be a good one to do our side by side split screen all right and let's go ahead and go over here so keep in mind we already have and undervolt being applied um interesting looking at our GPU boost clock I'm not sure that we're going to see much performance gain here look at our boost clock we're only hitting 21.45 right now we're not locking to the 850 right so this tells me that we may get better performance using a more standard a more standard overclock here so right now you can see we're getting we're hitting the high wattage our our millivolts there's only 835 we're not hitting the consistent 850 where we want to be because it just must be it must be pulling too much power it must be too GPU bound right now in this scenario and it's too much juice to pull so in this scenario uh looking at our average boost clock it's only 21.60 right so I'm guessing we can get a higher average boost clock by switching from this curve here over to a plus 240. let's try it plus 240 500 OC instead now let's see what our average boost clock is in the 2200s 21.90 with our GPU core voltage around 835 you know and this this may you may be able to help are we can we can adjust our curve to maybe try to hit these numbers so at 8 25 we want to be hitting a higher boost clock than what we were so what we can do as well we could we could go to our curve here and we can select our nodes and uh well we can do is we can move all of our nodes up a little bit higher let's say to 2200 or 22.70 this may cause us to crash but this may also help us I don't know let's see so we're adjusting our curve a little bit inside the game now our voltage is still not able to maintain and we're still dropping all the way down the curve further down than we really want which means that our curve is just too aggressive and if so if we actually look at our if we look at our curve editor when the game is running see what's happening our our node is falling down the curve here because it's too aggressive the GPU cannot maintain it with the current V bios um so the currently active node appears to be around this range all right and our average boost clock is only 21.60. so I I'm not sure that we're going to be able to get at our full performance out of this type of curve overclock so go into this standard offset overclock I think this is going to be our best bet so now look at us 22.35 that appears to be an improvement almost for sure all right so let's go ahead and run do a run through let's go and split screen our results there we go wow that is some performance gain Okay so wow oh my God all right 129 FPS versus 115. and look at our one percent low gain from 43 up to 105. oh man we just doubled our one percent lows more than double I don't know that seems a bit weird honestly but uh our boost clock like look at this look at this same moment we were doing 2200 right now on our boost clock versus only 2020 uh 2010. on the uh I don't know if that's just a temporary dip in the Boost clock or or what but that's a big difference and a 14 FPS gain on 115 FPS that's like a 11 12 performance gain in this game with much higher one percent lows that those higher one percent lows I mean I would probably attribute the one percent low gain to the under volt look at the CPU clock speed right now we're jumping between 4.8 and 5 gigahertz 5.2 gigahertz on the CPU and that means our clock speed on the CPU is just much much higher and that is giving us a huge gain to our one percent lows which is going to really improve the perceived smoothness of the game so let's like I want to look at this 3.7 3.9 gigahertz 3.8 gigahertz yeah our CPU is being knee capped basically before we had about a thousand a thousand megahertz gain in our CPU clock speed at the same wattage which is uh just really goes to show the advantage of undervolting that's insane um and the one percent low gains are just absolutely insane as well so uh that is probably our biggest gain so far today in gaming performance uh notice that our CL our temperatures are also six degrees cooler on the CPU uh with the under volt and the laptop cooler and Max fans and eight degrees cooler on the GPU so another huge not only are we getting way more performance we're also getting much lower temperatures in God of War hazam um and so also I suppose the active the the text over here on the right is actually incorrect because we're just doing a plus 240 offset right now uh for our our GPU boost so keep that in mind um it's pretty close but uh we're getting slightly higher increase to our GPU boosts okay so let's move on to our next game uh what's the next game we have uh cyberpunk 2077 let's go also keep in mind that we are running the games on different drivers which can impact performance as well Lion Stevens says wish Customs fans were available in every mode to give you option A more performance and performance mode because in real life usage afterburner HUD gives thermal limit warning yeah I mean I don't think we're gonna thermal throttle almost ever uh with the legion Pro 7i under normal gameplay scenarios even under performance mode because the cooling on the system is really good um that said maybe on silent mode or balance mode maybe you would but generally speaking performance mode ramps the fans enough or let's say after a while maybe your fans get clogged with dust or something and then yeah you probably would thermal throttle but uh the I have not seen thermal throttling on this laptop I don't believe in anything maybe dead space but that might be it what do I think of the Legion 5i Pro gen 7. could be good disabling e-core is the easy way to gain performance with Intel laptops and desktops you know that is a dedicated live stream I need to make Baka and see if that's true or not I've not done the test that's a great great potential suggestion though so not sure if we crashed right here it looks like we may have crashed again running our GPU at this offset voltage appears to be too much at 2 plus 240. in in the games that are CPU bound it ends up being too much so I think we gotta we gotta drop our offset to plus 220 and see if we can get better stability for our general offset gaming because I'm guessing we crashed right there because of it could have been a CPU undervolting crash but it's probably the GPU again I saw the GPU boosting up to 2500 megahertz um or close to 2500 megahertz which is very high for an RTX 4090 and I bet you that's going to cause a lot of crashes so that's where like utilizing the Curve the curve where we have a flat cut off it prevents our GPU from boosting so high that it causes the crash right so let's go ahead and get into afterburner and so we're going to change this to plus 220 all right so that's going to help us not crash as much when we're doing just straight offset overclocking and uh and generally speaking I think I'm going to use this curve uh ooc in cyberpunk and just in general I probably would use this curve with this flat Edge to help prevent those kinds of crashes you know you could you could let this curve come up a little bit more though if you wanted like you could let the h61 come up a little bit you could have this come up a little bit you could have this come up a little bit uh and then you could have it flattened after that if you wanted I don't know there's a few different ways you can mop you can keep playing with this there's like there's a lot of fiddling you can do to try to optimize your performance if you want to but this curve that we've set up here should be pretty good or you could just you know you just change this down to um a little bit less aggressive like I said maybe 220 or uh 200 you know 200 will probably be stable but yeah you could do hmm there's there's so many different ways you can do this the biggest issue why we're crashing right with the plus 240 is that when the when it's CPU bound it wants to jump to that really high voltage node which then makes the GPU go to like 2600 2500 megahertz and that causes us to crash so the key is to stop it from doing that which you could just uh take the two you could take this curve and you could drop these nodes to flatten the curve at um I'd say 25 I'd say 2400. so that way it never goes above 885. there's a hotkey I believe that can flatten everything down here and it's not shift enter I'm not sure what the hotkey is but there is maybe if we just lock the voltage to not go past 885 would that work for us let's find out maybe locking the voltage is the key that we need to be able to get stability here so I've locked the voltage so it doesn't hopefully go past 8.85. I think that will prevent us from crashing I think let's find out hell yeah Daniel I think the legion 5i Pro is probably a good laptop it just depends on the pricing like if you're gonna buy past gen Tech you want to make sure it's a really really good price um otherwise it's not worth it so notice that we're only we're maxing out 8.85 right now and we have not crashed our boost clock is not going above 2400. there we go that's good uh let's see if we crash as we load into here we appear to be more stable I'll bet you we would be stable loading into um so let's try doing this plus 240 now all right and we're still going to stay locked at 8.85. all right so that gives us that gives us all the advantages of the optimized curve while at the same time not letting the GPU run to too high of a boost clock causing us to crash I think this might be the right the right setting all right so we're gonna do ray tracing on Ultra frame generation will be on quality okay awesome now let's go ahead and uh uh get the split screen Benchmark ready to go here okay so there we go and let's get the split screen Benchmark here and let me go and update the text right now we're at 240. with 885 uh this is going to be offset with 885 millivolt undervolt lock so again you press Ctrl L on the 885 millivolt node so it doesn't go past that point and I believe are we got we're at plus 500 for the memory instead of plus 400 so let's make sure this is up to date as well we'll see if we're stable now we appear to be stable at least in the menus and everything all right so we're going to run the benchmark LSP says allow the voltage to run higher I reached 950 millivolts but the problem is when we raise our offset so high when it goes to 950 millivolts it's going to 2600 clock speed at 940 millivolts which is too high to be stable uh with the 4090 causing a crash so you said you can't go past 200 millivolts or 200 OC without crashing right now we're at 240 OC um and under realistic voltages we shouldn't be uh you know we shouldn't hopefully at least we should be able to reach stable stability basically that's the key we're trying to find the highest possible stable OC and it looks like we may have crashed again up here in the top right we're not making any progress on the loading bar we're not seeing anything updating here uh Windows shift B Windows shift ah Windows shift B it did it did exit US without us crashing hooray huzzah okay so we're gonna go down to 220 all right we're gonna go down to 220 for our offset and we're still locked at 885 LSP says My OC is 210 for Max stable okay gotcha well maybe maybe it's possible to push it past 210 if you were to lock the voltage so it doesn't run too high on the high end of the voltage curve all right so let's go back to the split again thank you for the tip on the Windows button shift B it did exit and save us without having to restart the machine save some time all right so we should still be good to go on our settings yep let's go ahead and run this Benchmark and see if we can load all the way in this time beautiful beautiful interesting interesting results so far keep in mind the game uh oh and our number needs to be updated we're at 220 right now for our offset so looking at our boost clock our GPU boost clock is going above that of the old the old one on the right but our actual FPS number appears to be lower um cyberpunk went through a big overhaul um recently look at our CPU our CPU clock speed is higher our GPU clock speed is much higher our one percent lows are about the same are are FPS according to MSI afterburner is lower though so that might just be cyberpunk having gone through the update and updated drivers and all that I don't know uh but we'll also need to wait for the end results here because the end results are the proper counter for this benchmark all right so we got 125 before in the past and we've got 120 today um so I think what we're gonna have to do is run this again by disabling our overclocks to see what our performance is um so right there we got 120 let's go back to the settings and re-run it again but let's turn off our overclock so stock on our GPU so this is the only way for us to get a most accurate test we're going to go down to no undervolt as well let's go ahead and run it back so this is no overclock now on the CPU or the GPU okay no underclock no overclock and no undervolt on either system but we are in custom mode all right we are in custom mode yeah so we are definitely hitting lower FPS than we were with the overclock down to I think we were doing like 1 15 ish right now and now we're doing 109 without an overclock and undervolt so definitely a nice Improvement for CPU and GPU performance looking at our CPU wattage doing over 90 Watts right now and that's obviously giving us great CPU performance but I'm pretty sure we were pulling a lot less wattage when we have the undervolt enabled um so going to show you that like undervolting your CPU in gaming workloads it really does reduce your wattage pull uh and temperatures because that's all you know obviously when you pull more wattage you're going to pull a higher temp too um it's interesting because we're pulling such high wattage on that CPU our GPU wattage is only 160. because we're pulling higher GPU wattage too at the same time okay so 112 with no overclocked no under under volt we got an 8 FPS gain approximately by applying in the undervolt and overclock which is quite nice um for free the free gains all right so next game is going to be Hogwarts and this is another game that may have gone through some changes but we'll see if there's any performance differences or changes here uh Brit Allen says I run plus 200 800 nice the one in the video had Vantage OC so Damon demon salad the thing is cyberpunk went through a big overhaul update uh that changed how Ray tracing Works to change how some of the graphics work and change uh maybe even some things about the Benchmark because we were getting significantly different numbers before and after that Benchmark came out so um like we we used to get higher FPS I believe uh previously like I believe in the past we were getting like 140 on the high end 144 I think in that Benchmark now we're only getting like like was one to 120 with an overclock so they made it more difficult to run so that's that's why I'm saying it's not a very fair comparison comparing three months ago to cyberpunk uh courage NASA says is it necessary to run overclock for games to run more suitable um well for example right that God of War test that we ran we doubled our one percent lows that is a huge gain and I think would be noticeable if you were playing side by side um that may have been a one-off we'd have to test it multiple times to make verify that result because it seems quite extraordinary but you do not have to optimize the laptop like this to get playable frame rates but if you're spending three thousand dollars on your system I mean once you get this thing dialed in you could just not do as aggressive as me and then you you basically would never crash just do a basic overclock under volt with the CPU and GPU um and you're not going to have you know you're not going to have huge problems I don't think all right uh you know you're not gonna have you're not gonna run into instability almost ever so why are you worried about it you know like like I feel like it's totally worth doing an undervolt and overclock if you just just don't do as aggressive as me I'm trying to maximize the performance take everything that I'm doing like I'm doing plus 220 right now on my OC just take it to plus 200 or maybe take it to a plus 180. um and almost for sure you're going to run into no instability I don't think uh and yeah so all right so let's just do this test twice uh we'll do no overclock here initially no overclock no undervolt this is our gonna be our our stock test and we're just going to run through here how's your gt77 sir I don't have a gt77 um but I actually I I actually uh Lance one of the subscribers just gave me his gt77 for some testing and then he's asking me to help resell it for him as well so I'm gonna try to help him resell it on my laptop list um but I'm going to do retesting I'm gonna test it live and then mention that it's gonna be for sale so it's going to be a pretty good deal on it as well okay so this is going to be all stock settings and um see what we get all right here's our run through stock settings no overclock no under volt on the CPU we got a nice GPU boost clock but that's because we're CPU bound right now only 77 GPU utilization our one percent lows are pretty good at 44. 105 FPS average right now 104 46. 104 46 is quite good all right it's obviously very playable considering we're on ultra settings all right so let's go ahead and we're going to apply our undervolt to the CPU right there and we're going to apply our we'll do our plus 22500c okay so this is just the stock OC curve let's see how this handles wow our we're doing 25.50 right now I don't know if we're I don't know if it's gonna be actually stable so uh let's can we grab the eight I'm gonna I'm gonna lock it right there okay so I locked it to 890 so our we're actually undervolting we're actually undervolting the the GPU a bit right now uh so Lance kept the scar 18 yes that's correct Brett he kept the scar 18. and he had he's gonna be selling so he he let his I don't want to basically his wife decided not to keep the gt77 and Lance had to decide between the scar 18 and gt77 so uh and he decided to sell the gt77 okay so I don't know this is so interesting this overclock situation um you know so under our our one scenario we've got plus 220 but we're also capping it so it doesn't go too high on the clock speed and then on the other hand we could do our curve under volt overclock and that is going to really cap us down to 850 millivolts and plus 220 2280 I don't know let's let's try let's try um there's a part of me that wants to just try the the straight 220 with no no frame cat or no voltage under volt let's just see if it's stable or not and what FPS we get all right well might crash 120 so far keep in mind we were doing 104 right was our average before so we went from 104 fps to 111 we also increased our one percent lows by a few FPS as well so that's a 7 FPS gain so about a six percent performance gain there let's try doing the uh let's see if let's see if doing our curve reduces our performance at all you know since this is such a CPU bound type environment you know doing this curve edit may not really impact our performance too much let's find out uh Joe says those temps are excellent on both the CPU GPU well way better than I expected for a laptop that size and power it's putting out more impressive than scar 16 thermals that's correct but we are undervolted we are on a laptop cooling pad the scar 16 would have these kinds of performance thermals I think if we had a cooling pad on it and everything and undervolted it and everything so let's see what we get now with our GPU under volt and overclock so we're not letting the GPU run as high and as hot as possible but the CPU bound game performance appears to be reduced compared to stock or very similar to stock GPU performance okay so that gives you an idea if you limit your if you do this whole uh on the curve editor your CPU bound game performance will actually be impacted right we just lost 7 FPS because we flattened the curve here at the end so that's super interesting so that's why I'm thinking doing something like plus 220 if this is stable at plus 220 maybe plus 210 this is going to give us a more consistent OC overall and if you really need to prevent it from running too high on the uh maybe just say limiting it to 2500 might be the right thing so this is uh locking it to 920 millivolts let's save it to one so that way the GPU does not boost above 2500 total clock speed and that'll help uh that'll help the GPU stay stable when it's in less GPU demanding environments and it doesn't clock all the way up to 2600 to crash it thank you all right so there's Hogwarts basically a 7 FPS gain in Hogwarts and obviously a nice drop in temperatures and wattages as well depending on what you're wanting to do you can kind of pick your poison do you want Max Max performance do you want better perform better temps all around what do you want we got dead space snacks here we go Dead Space being one of the very CPU bound games so this is going to be an interesting one to test look at all that dust on the screen this white balance on my camera went off for some reason I don't know why it's like all blue okay that's better looks like we got the wrong resolution again all right so in Dead Space I will try to compare this directly with the last time we did this test dlss on quality Ultra preset graphic settings all right let me go ahead and pull up the last Dead Space test um all right so here we are we're gonna try to do this pretty side by side some nice FPS gains right here 128 versus 136 notice our GPU is pulling more wattage our CPU is clocking nearly a thousand megahertz faster including 20 watts higher now that we're in custom mode I mean we're seeing some really nice performance gains here I'm in I'm super impressed um and notice our temps are also lower laptop cooler maximum fans um you know the thing is like even though we're pulling more wattage on that CPU we're still hitting excellent overall performance all right so here's our actual Benchmark area oh we're going to reset it apparently foreign lows are so crappy in Dead Space it still looks smooth and it's just and the frame time graph looks crazy but um like it's not stuttering on my screen and you can see on the live stream it looks smooth um but yeah the one time one percent lows are only 27 FPS right now which are really low so right now 133 FPS versus 123 such similar performance uh well such similar one percent lows but not good for our uh sorry better average by about 11 FPS gain there our one percent lows are almost exactly the same let me see if I can get the camera to move a little so we can see our one percent lows come on move 30 30 FPS for a one percent lows 29 for one percent lows with the overclock so one percent lows were not really affected much just slightly worse one at one FPS is not much of a difference but an 11 FPS gain overall so that's excellent then of course our temps dropped on both the CPU and the GPU because of the laptop cooler despite the fact that we're running 20 watts hotter on the uh on the legion Pro 7i so very interesting we are right now being at least partially CPU bound because our GPU utilization only 83 89 93 so we are being CPU bound to at least to a to a certain degree which shows you that by undervolting the CPU and overclocking the GPU you get the best combo of performance in this type of game with just one or just the other you probably wouldn't see the same level of performance you're probably getting some performance gain from both both of those things being done to the CPU excellent Okay so next up we have Dying Light two we got the Dying Light 2 Benchmark another Zombie Survival game foreign oh was August asking you Brit that was probably what it was okay that makes sense I was like I don't have a gt77 what okay so if this live stream has been awesome please consider giving the live stream a like so far not crashing loading into some games now that we've prevented the voltage from running as hard Ray tracing dlss on frame generation enabled these are all the same settings let me go ahead and get the uh the comparable Benchmark pulled up here and get it set up for the Stream all right and let's go ahead and go into the benchmark okay so uh out the gate we're seeing some performance gains 146 FPS versus 152. 151 versus 144. looking at our temperatures we've dropped about eight eight to nine degrees on the CPU and about 10 degrees on the GPU using the laptop cooler now I really needed to focus my Legion Pro 7i in the past live stream 146 versus 156. so 10 10 FPS gains so far notice our wattage pull being a little higher on that GPU our core clocks on the GPU not being too much different just being slightly higher the big difference being that CPU geez CPU is not only pulling more wattage but it's also pulling much higher core clocks Okay so 149 149 for our FPS in the past verses 161. so we ended up with uh 12 almost 13 FPS gain in this test um and that of course at 150 is going to translate to only about an eight percent performance gain from overclocking and undervolting and I gotta say I think the CPU is probably the one of the big areas of gains notice our our one percent low 142 for our mins 127 for our men in the past so we had a 15 FPS gain for our one percent lows under vaulting in particular is probably the thing that helped us with that pushing a higher CPU core clock is going to help with our Min FPS so excellent performance gain with our overclock and under volt in the legion Pro 7i all right so let's move on to the uh next test which is going to be shadow of the Tomb Raider and then we got Witcher 3. is it possible to do an all core overclock to 4.7 gigahertz uh well we were doing we were basically doing that with an undervolt we're doing 4.6 to 4.7 gigahertz in Cinemax R23 it's going to depend on what workload you're talking about because you know um like rendering an Adobe Premiere that's probably not going to be possible uh because it's a more difficult one to run but uh say that you're doing cinematr23 you probably can get 4.6 maybe 4.7 it's going to depend on your silicon Lottery and how much undervolting your system can handle um it's gonna depend did you get your ge78hx back I did and I got to do a live stream review Benchmark it's just I'm constantly getting new laptops and I'm like oh I got to keep doing these new laptops because it's a higher priority to get like the new laptop's done and I really just need to get back and get take care of that GE 78hx so I can get it sold as well so um okay so shadow of the Tomb Raider is next oh did we not do Shadow the Tomb Raider in the past okay so we don't have any shadow of the Tomb Raider test actually to do let's do uh we should have Witcher 3 though yeah we got Witcher 3 to do okay so so far we're seeing in the range of eight to twelve percent FPS I think in the lowest we saw like a six percent FPS gain um for this for the smallest gain but most of the time we're seeing like eight to ten percent on average I would say we want Ray tracing Ultra dlss to be on quality display we want to go to the full resolution frame generation on and so there's the um that's the load let me go ahead and get the split ready here um so on the right we'll have the Vantage basic overclock 150 200. and no overclock no under volt for the CPU and then on the left we're gonna have our plus 220 offset plus 500 with the CPU undervolt being enabled all right so let's go ahead and just run through this real quick all right and here we go wow we're doing 15 FPS more right now and look at our our OC on the GPU is much much better as well our CPU clock speed a thousand megahertz higher and our temps on the CPU 10 to 15 degrees cooler our GPU attempts 13 degrees cooler my goodness this is some awesome performance gain while at the same time being very similar levels of performance okay so um there we go let's compare numbers okay oh you didn't get to see all the numbers the whole time hmm should I redo this yeah yeah the yeah let's do it one more time I want the numbers to be lined up for this test so let's run this let's run this test back it'll only take another 30 seconds to do this one more time all right I gotta say I'm very impressed that there's almost no frame time stutters as well okay I'm gonna go ahead and play this there we are I accidentally jumped an extra time 131 132 versus 116 right now beautiful wow okay let's take a look at what we got here uh our our CPU Boost from the undervolt overclock and custom fan mode a thousand to twelve hundred megahertz faster 10 degrees cooler 12 on the 10 degrees cooler on the CPU 12 degrees cooler on the GPU are boost clock on the GPU is a hundred megahertz more than the Vantage overclock and our FPS gain was 14 FPS for our uh 14 FPS for our GPU or sorry 14 average FPS increase and 63 FPS increase for our one percent lows wow our one percent lows showing the a second second game that's predominantly GPU bound where the one percent lows got massively massively better you know one percent lows improvements in performance is crucial if you want a smooth high quality gaming experience and this under volt overclock custom fan mode it's really giving us the most performance and that's a noticeably better gaming experience going from 441 lows up to 100 like if you're playing it side by side you'd be like oh this one has a little less judder and it's a little smoother plus the 14 FPS gain is also nice because that's like a 10 12 FPS boost overall so awesome awesome sauce great to see that let's do a summary of everything so let me go ahead and exit uh exit this game and let's go over the final settings that I think I would recommend the most for overclocking the Lenovo Legion Pro 5i or sorry Lenovo Legion Pro 7i uh so first of all Throttle stop is the CPU or undervolting that I have decided to use you could use Intel XTU I think but I like throttle stops ability to quickly integrate and automatically it's very lightweight very easy to use and once you get it set up in the task scheduler it automatically launches and you get your overclock settings under under volt settings automatically applied inside of here my my undervault settings has my CPU core at -140 G uh cash at -115 and my CPU e core is at minus 90. these are not necessarily the optimal undervolt settings that you can possibly apply but this is what what worked for me where we we stopped crashing and some of those crashes may have been related to afterburner and our GPU OC most likely rather than this undervolt so I'm guessing we could probably undervolt the system a little bit more aggressively especially for maybe our cash and our e-course and we'd see a little bit more performance gain now in our cinebench R23 run that we did right here Shaboom we were getting a 12 performance gain from undervolting and and our time spy run we got over 23 000 uh 200 and a run I did yesterday I got 23 400. that's about a six or seven percent performance gain over the Vantage OC um so that's pretty nice but in actual games in Warzone Apex Legends um God of War we saw more performance gain than six and a half percent we were seeing more like I would guess 10 performance gains on average across the board and our one percent low performance improvements in God of War and in Witcher 3 were more than double but we saw one percent low improvements in every single game that we tested except for Dead Space where it was basically the same it was one one FPS worse actually which is odd but um such is the life of one percent load testing um yeah our biggest our biggest OC gains what would you say our biggest OC gains were I think the I think the Witcher 3 um and God of War were both around 11 12 uh plus our one percent lows improvements were also massive in those games so those are probably our two biggest gains but and those are GPU bound AAA titles so it makes sense but um I think the the one percent low Improvement is probably because of the CPU undervolting we did uh and then the fact that in custom fan mode we're letting that CPU just run like uh it's important I think when you're doing these settings to uh when you when you do your your custom mode inside of here we have our power sliders slid over to the right this is just letting our CPU pull more juice which the fact that it's pulling more juice we saw like a thousand to twelve hundred increase to our CPU core clocks in games which is definitely I think related to our one percent low improvements so it's a combination of undervolting the CPU also letting the CPU just run in this custom mode and then also overclocking in MSI afterburner or you could do it in the Vantage OC and if it's easier and more stable you could just do a 200 400 OC in the Vantage OC check box button and you don't have to worry about all this other stuff you probably are not going to crash but if you want to be able to push past that limit you're going to have to use something like afterburner and if you want to be able to prevent crashes beyond that this is what we ended up finding to be the most stable plus 220 500 and then we locked our voltage node to 920 at 2500. this prevents our GPU clock from running rampant and going too high causing a crash from going up to the 2600 clock speed range in those CPU bound games because when this when the GPU is not really that engaged it'll just ramp the clock as high as it can go and then it goes too fast and it trips and stumbles and crashes so this allows us to do a slightly higher OC without crashing um but otherwise you could probably go 200 without having to lock it here and you'd be you probably have very similar result but just slightly less performance um yeah and in certain games it was okay to let this run but in other games it wasn't so that's why if you want more stability I would use Ctrl L to lock it around the 920. Middle Belt range but maybe your silicon is better than mine and it won't crash anyway without locking it maybe you could go to 240 250 without crashing or maybe 200 crashes you or maybe 180 crashes you GPU overclocking is a per CPU chip solution and it's going to be individual to each laptop so your results will vary compared to the results that we got today I think a lot of laptops will be able to overclock and over under a little bit better than this one that we did today and some of them will be worse so just keep that in mind that your mileage will vary now I'm going to try to address any questions in chat and then that'll be it for the the test today Talha says hey dude you should you should remove thermal velocity Boost from throttle stop for plus 200 uh CPU performance when higher than 70 degrees interesting uh I'm not sure if that would help or not there's a lot of options inside of throttle stop right um I'm not sure and I I don't know every single thing in here there are there are a lot of different things you can check and enable and some of this stuff is like Legacy like speed step Speed Shift stuff like that this kind of stuff can be like related to past gen CPS that are no longer relevant and they may not even do anything or they might be messing up your CPU system but he's saying he's recommending potentially thermal velocity boost option remove thermal velocity boost option this is what he's saying to potentially uncheck interesting let's try unchecking that and then let's try running let's just try running Cinemax R23 and seeing if we see an improvement real quick maybe we will maybe we won't okay so we're doing four point five gigahertz right now 4.3.6 on the e-corse 158 watts of power this is slightly worse than our initial testing because we did reduce our under volt I don't think that thermal velocity boosts did anything really for us we're doing 32 500 for our score so I'm not sure if thermal velocity boost would actually do anything I think the big thing here is the reason why we got a little less than 30 30 000 33 000 is because a we're not focused on the window B are we slightly reduced our under volt so um that's going to slightly affect our CPU boost clocks so yeah I don't I don't think that that thermal velocity boost does anything but maybe hard to say we got 33 160 there just looking at the window a demon salad says much appreciated always have a good one thanks so much for stopping by Matt do you think it would be fine without a cooler with these optimized settings uh yeah no you don't have to have a cooler the laptop cooler probably just helped take off another eight degrees maybe somewhere in that range and then the CPU undervolt and the GPU undervolt depending on the game we're doing that also helps take off some additional temps um the additional four or five degrees because you got to remember there are some shared uh this is a shared cooling system in here so when you reduce the temperature on the CPU it'll also help reduce your GPU temperature at the same time okay does that help I hope that was super helpful this was an awesome optimization I think this is the most performance gains we have seen out of any uh optimization guide so far like about 10 performance gain in gaming and 12 and a half percent in CPU rendering there's some nice gains for free so yeah I'll see you guys in the next live stream which will be next probably Wednesday this is probably when the net so it'll be almost a week or about six days before I get into the live stream but I'll have some video edits for you guys to check out so be sure to subscribe hit that like button um some cut Downs as well as new comparison we're going to compare the legion Pro 7i versus the legion uh Pro 5 and then uh that's coming up and there's a couple other other full-on comparisons that we'll have as well so see you guys in the next one
