CPU Undervolting Guide | AMD Ryzen 7 5800X | Step by Step How To Guide | Ryzen 5000 Series

hey what's going on guys this is your boy c will back to you with another video and as you can see i know you see the setup yeah yeah yeah we got the ryzen 7 5800 x 5000 series cpu you're probably wondering what we're doing with this today as you see the title of the video we're gonna be under voting this has been a long overdue video a lot of people have been asking me about this and we're finally doing it today yes i know y'all like my tutorials and uh man i know a lot of y'all showed a lot of love and support for my gpu underwater video so if you didn't know i had that you could kind of hit that card or hit that link up in the top left hand corner below it also be in the uh description below as well you'll be able to find that link but that video is doing very well i know i got a lot of support behind that and i'm glad a lot of people was able to get their gpus up under control so definitely check that video out it's awesome so we're going to do the same thing for our cpu today and specifically um the 5000 series for amd ryzen and i have the 5800x which a lot of people know that particular processor is a hot box yes it's a hot box so i think it's only just a handful of people out there that it has regular temps per se um but a lot of people attempts we're getting up around about 90 degrees you know or higher in some cases and then you start thermal throttling a lot of different types of stuff so i am going to teach you how to be able to get that up under control and obviously the best tutorial that they have out there um to show you how to be able to do everything effectively so we are going to be using precision boost overdrive too and also curved optimizer to be able to get everything up under control so without further ado let's get going so if this is your first time here welcome here we do everything tech all things tech whatever it is we like to do it if you're a returning viewer i appreciate you the most because you keep everything going uh man if you want to see more content like this make sure that you hit like hit subscribe and hit the bell so you don't miss my notifications also if you want to help out the channel don't forget we got merch you can hit the link down in the description below we got all type of stuff we got hoodies we got t-shirts we got socks yeah we got socks we got backpacks we got mugs face masks whatever it is that you can think of we pretty much have it so make sure that you hit that link also um if you want to help out the channel the amazon links and all the stuff in the description below no additional cost to you if you just hit those links helps out check all right so first things up as you can see we have step one and yeah step one is download the right applications and what i mean by that uh so some of the applications that you're gonna need to be able to follow me in this tutorial today is one cinebench r23 you can actually grab that application from the microsoft store as you can see here they put in um the latest version of cinebench which is r23 um so you could go grab that you will also need um this hardware monitor this is cpu id hardware monitor pro um if i pull that up you can actually be able to download that here i'll put the link in the description below great awesome program so you're going to need that and then i actually just have the nzxt cam because that's the type of air that i have and it shows me stuff all on one gui page you know right here i also want to let you know for cooling for the cpu so i've been letting my system sit for a little while now so these are the idle temps so for cpus 42 43 degrees currently in the bios and we'll take a look at that in a minute um after we run some cinebench tests that but in the bios i have uh pretty much everything on auto except for xmp i got the xmp profile for the ram enabled the voltages are on auto i do have precision boost overdrive on auto so it kind of kicks in when it's supposed to per se and then i have my fan i got this on a performance profile and you'll see the actual fan speed and stuff like that kick in so i'll show you what that ramps up to right now let's get some basic stuff out the way so first first of all we got all the applications right so i'll just go ahead and put in here so just make sure that you we're going to use cinebench this is a to get our bases you know it's a benchmarking tool you know it pretty much does a really really good job of over loading the system like it's supposed to all cores maxing it out and all this stuff so we got cinebench r23 cpu id hardware monitor pro and then the other application that i don't have up is called o cct dot exe i'll explain a little bit later you're gonna need that towards the end of the video so occt.exe and i'll definitely make sure i have the uh link in the description below for you to be able to download that as well all right so that's step one now step two what is pb o2 and curve optimize i am going to do a brief synopsis over this and the reason being is because we don't need to get too deep into it right but i just need you to kind of understand a little bit of the lingo some of the information and all that different type of stuff but pretty much precision boost overdrive is kind of like an automated overclocking tool for amd basically but to kind of give you a little bit more information on that here are some slides that came from when this was announced um i believe yeah november 2020 actually these slides actually come from uh tom's hardware and so it talks about precision boost overdrive two single thread brings pbo benefits to lightly threaded cases multithread preserves the existing nt benefits of pbo undervolting introduces core underbolting for ryzen 5000 series optimizes the entire voltage curve for your curve optimizer now it talks about the differences between pbo and then pvo2 so regular pbo you know you can raise the actual socket power limit raises motherboard vr vrm limit overclocking uh can override max boost frequency primarily designed to improve nt performance and then you have pbo2 i kind of talked about some of this stuff already uh improved performance per watt can lower operating temperatures customize voltage frequencies to your specific processor um now here's the key thing i want you to kind of not necessarily remember but just keep in the back your head you're going to see these a little bit later in the bios so package power tracking ppt that's measured in watts power right the amount of power the processor can draw from the socket before the boost levels off higher ppt can improve heavily multi-threaded workloads electrical design current edc the peak current that the motherboards vrns can supply under transient conditions higher edc can improve short duration high intensity workloads thermal design current tdc measured in amps the amount of current the vrem's can supply over a sustained period higher tdc can improve heavily multi-threaded workloads and precision boost overdrive scaler tails the boost algorithm to use higher voltage for long periods of time to sustain boost activity that may otherwise be throttled back higher scalar values can improve boost performance in scenarios that might be limited by max voltage or voltage duration boost overdrive curve optimizer yeah under voltage can free up high um additional voltage and thermal heat room for higher frequencies along the boost duration all right um and i'm not going to get into this other stuff so that's that now the other portion to this understanding the curve optimizer so the curve optimizer like overclocking no two processors are alike some processors have more underwater head room and have less and some have less more heat room where process load is low less when load is high typical undervolting only optimizes work case workloads curve optimizer allows under voting they can adapt to both light and heavy workloads this is the key curve optimizer tells the firm where the uh what window of vulnerability is desired by the users relative to operating conditions all right um and i'm not gonna get into the rest of this um and coincidentally this is using the gigabyte bios which i have um and it talks about one count so keep this in mind as well one count worth um is approximately three millivolts to five millivolts um so this actually ranges between 10 millivolts to 30 millivolts so 10 count well not i'm sorry 10 counts to 30 counts so you can either do plus um or negative and we're going to be more so going about the negative because we're going to undervolt um so 30 counts equals 90 to 150 millivolts let's keep that in mind uh and this talks about some of the settings tips and tricks um i tried some of this stuff out for you already um and none none of these actually work out the way that you wanted to because the ultimate goal is to be able to get lower temps lower wattage lower power higher boost and either the same or higher performance right and so those are like the positives those are the things that that you want to be able to get out of this and i'm going to show you um the difference in between those so now that you know a little bit about this type of stuff let's go ahead and minimize that i don't want to spend too much time on it we're done with step two so step three is we're gonna run cinebench and again um i pretty much have everything on auto in the bios except for xmp i got the xmp profile enabled so once we get inside the bios you'll actually be able to see what my settings are right now and what we are going to change those settings to to be able to um get what it is that you're looking for all right so let's go ahead and hit start this lasts for about 10 minutes um and i am going to point out a couple of things in the beginning then i'm going to do some youtube fast forward so i'm going to speed up the video and then we'll see the end result um that's going to come from that we'll jot down the actual score in fact i'm only going to do this once because i just want you to see what the actual temps get up to all right so let's get started so we're going to hit start now obviously this is the cpu multi-core um and again this runs for 10 minutes automatically so what i want you to pay attention to um as you can see here my cpu is being 100 overloaded um the temperature now i have a 360 millimeter aio so um let's let's let me just show you i'm just going to type out my system specs just so you know the system specs right um so we're running cinebench so here's what i love about cpu id so here the cpu uh v core right now it's at 1.296 so let me put that in so v core 1.29 um it will also be listed here but you just put it from here the max is 1.440 because that's it's on auto max 1.440 we could jump here to that's the current package tip so right now say 83 degrees and it may get up higher you know the longer that this runs that's typical my ambient tip in the room is 21 degrees celsius which is like 70 degrees package power and watts the max i'm just gonna go with the max 133 is bouncing between 130 watts which is power clocks now this is important so right now what you are seeing the value is 4.6 i'm not going to take the max on the clocks here because it's all about what is running during the sentiments run well let's say it's 4.6 i have pbo selected as auto uh inside the bios if i did not have pbo on and i just had it disabled uh the actual boost clocks would not be this high whilst inventions running so just fyi i just want you to know that like default pvo is not turned on um but pbo for a lot of people works out and so that's why i had it on um if you want me to be able to test that with people i'm just letting you know now if you disable pvo the boost clocks are like 200 megahertz less basically um when you're using you know a full workload like cinebench um is right now all right so we'll fast forward the rest of the way okay so as you can see here um we finished off with 15 024 in the center bench so let's just put that in score was thousand zero two four multi thread we got this down um actually the highest uh temp that i saw was 84 degrees of course you know we already took down what the actual boost clock was while um this was running let's check out the bios okay so we are inside the bios uh as you can see here um everything is pretty much on auto right cpu v core auto um the only thing that i have enabled is the xmp profile like i said earlier now one thing that you need to do is make sure that you update your bios to whatever latest bios that you have um you need at least the agiza 1.1.8.0 um in order for this to work obviously you know you need a 5000 series cpu amd and you need a 500 series motherboard um i think people try to use this for others and it doesn't work so that's either the 5600x 5800x 5900x 5950x so what do we need to change um but if we go over here to settings we go down here to amd overclocking hit accept um and oh one thing i also forgot to mention uh frequency and timings uh for the infinity fabric i do have mines set to uh a one-to-one ratio with my ram so my ram is running at 3600 half of that is 1800 so an infinity fabric should always be half of whatever your ram is so i do have that set just fyi all right so let me back back out so we're gonna go to amd overclocking hit accept go down to precision boost overdrive so right now like i said i had it on auto most people um when they do this it's disabled um so obviously you'll see you know not so high boost clocks usually like 4.4 gigahertz stuff like that for the boost clock um when you're and that's usually when you're hitting the cpu 100 load um it drops down in order to keep the actual voltage and stuff in check but i have pbo on auto okay so what we want to do is actually go to advanced i already had some of these settings in here um so i had to go over here to make sure that you change pbl limits to manual now you will see some stuff that say okay yeah you guys should set this on motherboard let me show you what happens if you set this the pbo limits to be based off of the motherboard like it didn't work out in my favor so when i said it's a motherboard see then you can't make any of the changes like you need to so make sure that this is on manual now here's the thing you could start off you remember what i was showing you earlier uh it talks about ppt which is the power limit um tdc edc that's the amps well you could start off with these um but you can kind of play around with the numbers to see what works out for your chip i use some of these numbers off someone else um that actually um undervotes it i was looking i think i was on like some reddit um on some reddit thread and they use they actually use 120 85 130. that worked for them but for me i had to do 120 75 130. um and so you can kind of test these out see if it works for your chip if not you can play around with some of the numbers i'm going to be honest with you um when it comes to the power limit it's just about okay hey that's 120 watts um that the actual that you're letting your board allow um to go and then as far as the amps um i never really got too deep into that and so i kind of piggyback on what other people use as a basis and i kind of mess around with some of the numbers until i got a stable system and so when it comes to underbolting this is pretty much what you have to do um you got to play around with some numbers but i use this as a basis so um as a basis and i figured out this is what works for my boy you know for my cpu every cpu is a little bit different but you can start off with these numbers and you can kind of go up or down um until you know you get something that works for you if i go down here to the second step is to precision boost overdrive scaler leave that on auto curve optimizer so here's another thing so you click on that curve optimizer i set mine to all cores all core curve optimizer negative so i just want you you can either do positive or negative negative is because we're actually doing an undervolting and then up under the all-course option you have disabled you can do a perkor now i've seen some people do this per core i'm not the type of person that gets that deep into it because you could depending on if you have two ccds like if you have a 59 5900x or 5950x you could do two ccds and you could set um you know you could use ryzenmaster to set you know which chords that you want at different levels and um you could get real deep into it or you kind of do this the quick and easy way and i i lean towards quick and easy because again i want to have just balance between attempts and performance so all cores negative so you have different options um you can set this from 10 to 30. what i found out you could start off with 30 and then if your system doesn't boot then you'll know like if it doesn't like if you can't get past the boot screen you'll know that you need to go in here change this right um so you sometimes i've seen people start off with the curve optimizer first before they even change any of the power limits and stuff like that um but what i found out was that the i never got the temps where i needed to be without making the other changes and so it's probably good if you just do everything at once and then you can start playing around with it so um i initially started us off at 30 for the optimizer magnitude and but i couldn't do 30. um so i had to drop it down and i recommend that you drop this down in five increments so each count is like one to five or is it three to five well what is it yeah so each count is three to five millivolts so i recommend that you go in steps of five and so if 30 doesn't work drop it at 25. for me 25 work but if 25 doesn't work drop it down to 20. if 20 doesn't work drop it down to 15 all the way till you get to 10. i don't think there's anything worth past 10 and might not even let you change it but do it in steps and sometimes it takes a while because you know what i had to do is that once i changed these settings i went back into windows and ran cinebench again rants in a bit again as long as i didn't crash i was good but you also need to do a stability test and you need to use your system you know for for like a week or so play the games do all the stuff that you would normally do stretch the system out um and so stable so we're going to use a program called occt that my guy in my discord one of my mod technological uh he actually hit me up and told me he said hey you should use this system out so uh speaking of discord make sure that hey if you want to join the discord to learn some stuff but occt which i'll show you when we get back into windows i use that for stability um and what that taught me was that you know it'll test out each core um using abx and all this different type of stuff um to be able to make sure that your cpu is stable because the worst thing that you want to do is actually in which i am not live before when you're making these changes to your system you don't want to uh mess up your cpu there is a potential is there anything with undervolting cpus or overclocking cpus whatever the case may be there's a potential that you could mess something up if you keep settings for something and you start getting cpu errors and stuff like that um so i am not liable you know which is why i'm telling you to do this stuff in steps um you do this at your own risk um but if you plan on doing this here's the steps and stuff that you should take and i've had no issue with my system um other than you know like not moving into windows then you gotta go back in and change the settings and stuff like that uh worst case scenario you can revert your bio settings to the default bio settings if it doesn't boot so don't panic so if it doesn't boot you can revert to the you know you just go back to you know your basic settings and stuff like that and you'll be good to go um so but here is what i have so 25 so these are the numbers that work for me um the max boot on max cpu boost clock override 0 megahertz um and everything else is on auto so now that we have this i am going to hit f10 that is going to um save all the changes that i've made um and yeah we're gonna go from there splash screen okay so we are moving on to step four [Music] so in step four we are going in well actually i wasn't doing it but step four because i wasn't inside windows so what we did is we enabled manual mode on pbo precision boost overdrive uh changed ppt so i put it right here ppt um e edc the tdc so ppt was 130 [Music] 75 [Music] 120 [Music] then the curve optimizer it's 25 everything else auto boom alright so we did that so we actually moving on to step five and in step five what we're gonna do is we're actually gonna run cinebench again so we're gonna run cinebench all right so we're gonna start this and i'm going to hit start [Music] and the biggest difference that you are going to see and you're going to see it firsthand is obviously the temperatures um but yeah you're going to see the biggest difference in temperatures and also the amount of watts being used and remember when we were talking about the power limit um you know it's 130 um and then the was it the thermal design current it's 120 right so in the edc is electrical design current uh so these two are measured in amps power limits measured in watts so [Music] as you can see here it's already been running for like a minute um originally our max 10 was 84 degrees right [Music] and so far and obviously this will need to run a little bit longer so far max temp 76 degrees 76.9 on the package um max power 120 watts right so i want to let this continue to run um and then we'll come back and take a look at the numbers um and we'll look at the difference in between the two and we'll take it from there um it's actually supposed to be 15 000. but yeah we'll let this run you know this is a 10 minute run on cinebench so we'll come back towards the end uh one thing i just want to point out um the boost clock really didn't change all that much um it's still 4.6 uh whatever the case may be is while you know 100 load on all the cores and so that's just something just to keep in mind the biggest difference is the max temp has only been 77 degrees so what is that three four so we're talking about with the settings that i use the difference is seven degrees but i'll let this continue to run so we'll do the same thing so i come back okay so i am back so we got about three minutes left in the cinebench run as you can see we still maxed out at 77 degrees we still max out at 120 watts for power and so yeah we saved on power so let's look at this so v core i'm seeing 1.23 1.23 and then max um is i just saw that raise up so it's 1.42 max 10 77.3 watts which is power 120 watts max and then boost clock is pretty much the same 4.6 4.6 [Music] let's bounce it around 4.624 and like i said if you're not using pbo at all you'll see a more dramatic difference um because again if you were doing all core workload and you wasn't using pbo um you were probably max like 4.4 gigahertz 4.3 gigahertz um you know during a run like this and so you know when you're on the vote you'll actually get if you do everything right you'll get this same type of boost clocks by doing a full you know a full load on your cpu and um so your game 200 megahertz easy um plus you have lower wattage lower power um and lower temps so look at this so we originally had 15 000 024 so now with the changes that we made we had 14 000 and the these differences are negligible 14 940. so we're off by 80 points so that's not that you're not gonna see that so that means that we're pretty much getting the same performance less temps less wattage so if you if you was planning on using the 5800x in a small form factor bill which is what we talked about doing uh man you could be able to drop seven eight degrees easy and so you don't necessarily have to you you could use air cooler really you know even with that um and still be able to do what you need to do um or even if you wanted to switch over to a water cooler you know obviously in a small four factor build you can't you could use a 360 millimeter aio but you can use a 240 or 280 you know depending on the case of stuff that you have a small form factor bill but again this allows you to be able to do it so i want to know you know what are your numbers what you was able to get figured out um you know if you have a 5800x you know does this help you out does this not help you out have you already tried certain things but i run this under vault every day and the thing that i love about it is that is everything is done from the bios so you don't have to you don't have to mess around rising master any other different type of stuff you can do everything from the bios um and so once you figure out your numbers you run center bench um and you can able you're able to get through cinnamon bench at least through three passes so uh what i would say is in step six run this three times no crashes so if you can run this three times no crashes this the last step for today um is run occt and and we're pretty much going to torture the system so what we're going to do is we're actually going to run this i'm going to pop this up show you some of the settings and stuff that you should do um so this is done correctly um and then as long as you pass that you can actually be able to run those settings you know you can run them every day um and then you can test test it out in games and all this different type of stuff um after that but if you do not pass the occ test i do not recommend that you keep those settings because i thought i was doing good because my system was running and then i failed the occ test um because like some of the cores was running into like errors and stuff like that and so what i found out is that you have to run this test um because it tests the cpu all right so let's start up occt okay so here is occt all right now you should be able to see everything fold cct okay on the um bottom left-hand corner here a couple of things you're gonna when you open this up for the first time change this to 45 test duration it's 45 minutes data set large on the mode is gonna be extreme low type variable starts like a one introduction uh set auto threads advanced and then advanced thread settings you're gonna hit this cog wheel and then you actually all of these are gonna be checked but you're actually just going to check just the first one core zero uh virtual course physical only course cycle you want to change this to every five seconds uh swap active inactive course disable um and then you're gonna hit check so this is gonna cycle through the through each core every five seconds so you're gonna hit check and say and then once you do that [Music] um here you could yeah you can actually you know keep track of all of this at one time it's going to show you all the temperatures you can actually click on all it's going to give you everything but if you want to click to see what the voltages are this is a good program to be able to check all that stuff while this is running um you can even be able to check out the uh the power the current you know fan frequency you can check all this different type of stuff the usage whatever um tips doesn't matter once you hit start this is going to run for 45 minutes so what i'm going to do is i am actually going to hit start so obviously this is a free program but they act for patreon you know support you know if you want to help them out and then we're just going to hit the play button here and so now here's the thing this is you know avx2 instructions you know all this stuff is running if you see anything other than green down here uh then you you need to go back and check your settings so i've ran this test before um i'm just gonna go ahead and just let this run again i come back four to five minutes from now um just so you could be able to see that i have no issues with the settings that i chose um but yeah let this run and again you could be able to check the temps you know what they get up to you know the packages and all the different types of stuff you can check out this stuff here hey so i'm recording this i made a mistake um with the actual numbers that i put in my guide here so you know if you watch the portion so make sure that you hit the timestamp you know during the portion where um i said hey here are the changes that i'm making in the bios the ppt is 120 on the edc is 75 and then tdc is 130. i had the ppt and the tdc swap so fy let's keep it going all right so as you can see we're coming up on the end of our test and as you can see we maxed out at about 80 degrees uh on attempts this is an extreme test abx2 um set you know no errors uh which is great because i already know the numbers um but yeah once you find out you know like what numbers works uh for your system this is the ultimate test and i was so happy my guy put me on to this again i wasn't having any issues and i was running these numbers and stuff like that and when i started running this that's when i found out i was like oh so if you want a rock solid system make sure that this is the last thing that you do um it runs for 45 minutes um and it's great and then you know from there you just use your system like you normally would test all your games and all this different type of stuff and i haven't had any issues and i get the benefit of you know lower temps and uh lower wattage power all this different type of stuff so um definitely let me know what you think down in the comments below um again you know hit me up let me know like what are some of the numbers that you use um have you tried underwealting before how did it go if this got help don't forget to hit like hit subscribe hit the bell so you receive all my notifications you want to see more content like this definitely share the video hit like interact with it i'm sure it is you know wherever possible so you let youtube know that you like your boy um so again i appreciate you for watching this video all the way through if you want to see my gpu underwater video definitely make sure that you hit the link down in the description below and i also um make it a part of the ending of this video
