These are our highest AMD overclocks yet... BUT...

I have no idea I got to scratch my forehead that's scary the Corsair Vengeance a 4100 offers a professional streaming setup out-of-the-box with the included el gato 4k 60 Pro video capture card capable of recording 4k HDR 10 gameplay at 60fps the Vengeance a 4100 series features high performance horizon 7 3000 series processors in an NVIDIA r-tx 20 series video card with plenty of performance to play today's top titles with incredible detail and frame rates to see the complete spec list and to learn more click the link in the description below Oh with all this hubbub about the AMD XT processors and stuff I'm gonna do something we haven't done in a long time and that's actually talked about overclocking an AMD processor if all goes according to plan I'm gonna show you guys why he really shouldn't bother so for this particular test we're using an asus crosshair 8 hero board which is really one of the higher-end motherboards you can get for AMD obviously the BIOS stuff we're gonna show you here is gonna be dependant on your motherboard manufacturer so you'll need to you to RTFM yourself there's only a couple of things we're gonna change in the BIOS normally when it comes to overclocking I prefer straight-up BIOS overclocking I don't like software or operating system based overclocking stuff I'm like using any of those apps that you can get for your for your CPUs some motherboards offer their own operating system app to control the BIOS will be using Rison master for this which I don't care for but the reason why we're gonna do that is because you don't get all the options in the BIOS it's a first understand overclocking on AMD you've to understand how it's constructed how its glued together on the mainstream dies or chips when it comes to CPUs from AMD not including thread Ripper third Ripper is actually like twice what we're about to say there are two CC X's and basically I guess the easiest way to look at it is they are two sets of course and then they work in tandem that's where the whole load they're glued together they're really just two CPUs whatever I mean who cares how you get the performance if you get the performance what I would do on an Intel system quite honestly is I would just go down to the core ratio and I would just be like now this or until I'd be like let's go fifty four five gigs right now you know I can't do that nay indeed but and then this is the memory stuff right here this is kind of not really that important when it comes to CPU overclocking but for the most part just set it to do CP and you know call it a day but you can see right here we've got CPU core ratio per cc X when it comes to the core a she oh it's zero and one so actually on like a thread Ripper that has four cc X's at zero one two and three which is weird have a counting starts at zero but it doesn't really matter what this allows you to do though is set the multiplayer multiplayer multiplier for all those cores on the CCX we don't want to do that because AMD automatically does and I think Intel does this too but specifically on AMD what we're talking about today it will find the best cores on your cc X's and it will automatically push for precision boost overdrive PBO it will automatically push the maximum turbo clocks to the best course that's going to be done for a couple of reasons one stability - it can usually do it on lesser voltage this CPU the 3100 XT will precision boost overdrive a single core to 4.7 gigahertz well if we locked our CCX ratio at let's say 43 or 44 which is typically what people are able to get on all core actually all cores more like four two sometimes four three what that has now done is taken 400 megahertz away from our single threaded performance and that's something you don't want to give up because of gaming games tend to really benefit from higher core speed and it doesn't load all your core so you want them to be able to go up past you know where are all Corbeau Spock's gonna be so anyway we just are gonna leave that at Auto but what we want to change is a couple of things when it comes to our power drop what we're doing here is we are just setting our CPU current capability to the maximum which is 140 percent that basically means the CPU is allowed to draw 40 percent more current than OEM specifications now that doesn't mean it's gonna automatically do it that's only if we start overclocking and no revolting it enough to ask for that much that's what it will be allowed and that's something you typically wouldn't go anywhere near unless you're doing like the ln2 type overclocking like Steve I showed with he's played around AMD stuff Ellen - I haven't done that yet but you definitely need to go with as much current capability as you can otherwise you're gonna hit power limits and stuff way before you ever get to your max clucks or stable clock speeds the other thing we're gonna be doing here CPU power thermal control that is essentially where the CPU will turn itself off and I think defaults 123 is set to 136 because I was troubleshooting something before making this video and then the other thing we're going to change it here in the BIOS is precision boost overdrive this is normally set to auto I had it set to manual because I wanted to see what we were able to change here with some of the power limits right here so we set the PPTA limit to 175 because we just won again give it Headroom TDC an EDC limit I just left those alone and platform third throttle limit or else well fall along ok if you leave it at Auto it's gonna manually throttle at 95 I have it set to 100 again a little bit of uplift so those are the settings that I changed in our BIOS so far that will have zero effect on what our CPU is gonna do again all I did was relax some of those limits now when it comes to the logic of overclocking AMD unlike Intel there's three ways you can do it you can go with precision boost overdrive which is where it will automatically overclock itself up to those maximum turbo frequencies that you see on the spec sheet for your particular seat view in this case of the 3,800 XT single core will go up to 30 40 700 megahertz and then all core will go to 4.3 so you've got default precision boost overdrive auto overclocking and manual now one of the things that I wanted to play around with here was to see if we can actually set our best cores to try and go farther than the four-point-seven doing an individual per core overclock like you can't on Intel unfortunately on rise and master although it looks like you can do that it doesn't actually let it let you do it now this might seem like I'm doing an overclocking tutorial I'm really not like I said my my goal here is to show you that the amount of tweaking that you have to do to get any sort of tangible improvement over what the CPU is able to do on its own isn't worth it and and you know I mean if you guys are like me you like to mess around with stuff anyway but there becomes a point where you just it's just not worth it it's just not worth your time so if we click back on our profile and we apply it you can see right now three-point-nine is all it's showing us on all of our cores because we're set to manual so there's no precision overdrive happening right now so if we go in here to Cinebench our all core only went to 3.9 and that's because that's the that's the base clock of the CPU when it's under load that's the base that's as low as it will go unless it's starting to really thermal throttle itself to try and stay alive 3.9 is where it starts anything above that is actually considered an overclock so because we're set to manual it's not gonna go any farther than that so as we just demonstrated right there 3.9 gigahertz if you set it to manual and we're just gonna see what our score ends up being set we can have something to compare it to as we move forward here so that score was a four thousand six hundred and sixty one significantly lower than the factory score that you would get if you hadn't touched anything so let's go back over here now to manual overclock and what I want to sort of demonstrate although it makes it look like you could get some sort of a per clock or per core overclock so I've set our best core in the system to four point seven and we know it's the best core because it has the gold star ii dot over here is telling it as a silver dot it tells you right there it's the second fastest core of CC x1 but if you do the gold star will stay right there it's the fastest core in the system let me come over here and run our test again and we take a look at our core speeds here at our monitoring by clicking home well that one went up to four points and seven like we set it to these are still a three point nine but look what happened here these dropped to three point seven six zero so what Phil and I have been kind of messing around with here is trying to see if we can't get this to individually boost but we've noticed every time we set a core to go to a higher frequency the other cores compensate by dropping and we don't know why that is because those cores are set to 3900 but they dropped down to 37 60 and look at the temperature right here the temperature is still at eighty two point five see even though we have a Celsius s 36a io a 360 millimetre weight water cooler on here the temps are still getting Korea T damn hot and the reason for that one point four six two five one volts which is way more voltage than it needs but when you leave it on auto that's what it goes to in fact this is what caused a lot of the discussion recently about AMD's core clocks and voltage algorithm being way out of whack I guess some guy at TSMC even said one point three should be the max you ever run regardless ours is significantly higher jokes aside everyone was always like teasing Intel for being a hot CPU now and AMD being a lot cooler AMD will run freaking hot the moment you start trying to play with all core overclocking and even though a seven nanometer it is pushing so much more voltage and we get on Intel Intel also has a higher Headroom by default than AMD at 105 see where AMD's at 95 so that's the first thing I wanted to show you is that once you start doing an all core overclock you're gonna end up limiting your your maximum core potential on your best core now let's go ahead and do this let's go to precision boost overdrive so four point three across the board and now I want to I want to talk about that for a second because prior to us getting our hands on this 3800 XT I could not get four point three gigahertz all core to run on any of my rising CPUs from well getting over four gigahertz on Rison one or Zen one was really difficult most people running three eight three nine go back and read all the old Tom's Hardware as a nanotech anon tech articles and you'll see three nine four oh four oh was like the got the golden chip for one was like you you won the lottery three nine was about the best you could hope for then plus came out and we started seeing four oh four one across the board now then two is out we were seeing four one four two I could not get past four to matter what I did this is running for three all core out of the box we didn't touch nothing and our temps were sitting at seventy three Co if you saw that we probably were looking at it was at seventy three see our score jumped up to a 5100 33 that's up from the 4700 and some change of us already going to the manual overclock and trying to screw with it now there's nothing we can do here we can adjust this at all when you stay in precision boost it's it's all set if we now do a single core we should see these two cores swap those are the two best cores in the system and the reason why you're gonna see them go back and forth is because of focused heat on the die it doesn't want to run long prolonged sustained workloads on a single core for a long period of time because then you'll get hot spots on the die and that can actually cause problems physically with the the die itself also too even though these other cores go to sleep these are still pulling one point four seven volts whether or not it's too much I don't know there's articles of people saying that's way too high member this is Otto we haven't touched it builds IDE his 3700 X is it graded to where he can't even get factory speeds to run anymore because of the voltages that it was running I said when this first came out I thought that was too high and people told me that I was an Intel fanboy but a lot of people are saying that that voltage is potentially too high but I I'm not an engineer so I can't say that but I can tell you that if I go in here and under volt we get the same results in fact better scores even because we don't bump up against a thermal head room or that thermal head limit had thermal limit thermal head limit room now the third type of overclock here is the auto overclock and what I want to do is show you how auto overclock doesn't really do anything so Auto overclocking is enabled you can see now the only thing we're allowed to adjust here is the TDC the PPT you see how the PBT is set to 1:25 that's normally I think 120 or something like that the reason why i showing 175 is because that's what we set in the bios so if we set the limit higher in the bios that becomes our maximum limit here so as you can see I can click the down arrow and go down from there but I can't go up above the 175 but I could if I set that limit higher the BIOS so that's why I showed you that first if you're gonna try and do manual overclocking you have to lift limits in the BIOS before they even become available here inside a verizon mask and then the boost overrides CPU that's that frequency I showed you where I said it can go up to 200 megahertz over that's what that is so we allowed it the auto overclocking to attempt to go 200 megahertz faster than the then you would get a PPO or precision boost overdrive 4.3 across the board is where it went now if you look right here at the CCX in the gray area it actually has a target right now a four point nine to five that does not mean four point nine to five on all the course it means four point nine to five for the fastest core that's what it's supposed to be trying to go to and that's because it added 200 technically 225 but it added 200 because we set 200 plus to the precision boost overdrive but it's not doing it for six six eight four six nine two and then just swap to the other one for seven everything is in the green and nice and low it didn't even attempt to go there so here's what I do were quick I am gonna show you guys my maximum manual overclock that I was able to achieve out of this and then what we'll do is we'll compare the manual overclock that I got to the precision boost overdrive which is just the CPU doing it itself and we'll do the same six tests that we did in our review and it will compare those results to see and what's funny is I already know what these numbers are because we've literally spent a day finding these numbers and you'll see what the differences are and then we'll talk about whether or not it's something you should even bother wasting your time with [Music] [Music] [Music] all right so as you can see in the benchmarks here my maximum clock that I got on all course is actually very impressive 4.6 gigahertz across all cores that's not something I could eat could come anywhere close to one like the 3100 X when we first got it or even the 3800 X or the first 3000 series verizon processors so clearly the XT the 3,800 XT that we've got at least I'm sure the 3600 the 3900 XT are also gonna be binned processors that's why they exist with a higher core clocks capable to them out of the box now one thing that we did by locking the cores at 4.6 gigahertz is we took a hundred megahertz away from the single-threaded performance like we showed but what you might notice if you look at Cinebench in the single core you might go we'll wait a minute if four seven is the maximum core clock for single core how come at four six got a higher score well that's because of the uplift of the power limit even though we have only a single core going to load it still has to fall under the same limitations in terms of power limit and power drill and all that per core not just for the entire package so by bringing all of those limits up meant that it was able to actually stay at four point six locked without fluctuations at all what we actually observed with four point seven with factory settings is that it would kind of bounce around a little bit it also changed off-course quite a bit and every time it has to hand off that skip that task to the other core there's kind of a puzzle of a latency happening there as that core then ramps up and then goes up again but what we saw was with the increased power limits that wasn't handing off it just stayed actually on the second best core the entire time it didn't even go to the first core and the reason why I think that might be and this is all speculation here is that four point six is what the second best core is probably tested or validated up to in terms of it being best so since we weren't going for seven it probably didn't even need the it didn't see the need of sending that task over to the best core because the second best was able to handle it for what we were asking it to do and it just had to read to do that and I think that's why our score came up but at what 531 single core score and Cinebench that just goes to show how the improved IPC with AMD and then as you increase the core clocks really do start to catch up to Intel's aging architecture on 14 plus plus plus plus plus plus plus plus plus squared architecture now when it comes to gaming well actually me finish my other thought here is when it comes to multi-threaded performance so at four six across the board that is a 300 megahertz jump across eight cores and sixteen threads so obviously Geekbench Cinebench and blender all saw significant improvements up to double digits around anywhere between eight to ten percent improvement now when it comes to games not so much and that being because for six gigahertz on all cores was pretty much enough to no longer really be a bottleneck on the 28 ETI that's slightly overclocked now I saw some comments in my previous video saying by using this graphics card we were artificially causing ourselves numbers that seemed skewed because this cooler is already slowing down the card and you know for various reasons you know we should have used a different card this was overclocked with power limits moved all the way up and the fan speeds actually set to a hundred so the core clock on the graphics card did not fluctuate it stayed at the setting where we set it so that was not an issue right there it's one of the sort of address that if you saw this here when was thinking that had anything to do with our scores not changing really with fps that's not it a for effort but your arguments completely flawed when it comes to the increase though that we saw in the single core it's just like on the GPU where you move that power limit slider up and so you're not seeing the fluctuations in core clock was the same thing that was happening at single core so we actually saw a benefit to single core and we saw obviously a benefit across the board in multi-threaded tasks games really not so much now on the surface this might seem like well okay J you said to begin this video you were going to tell us why you shouldn't overclock AMD it might seem like well I just made a really good argument as to why you should there's a lot of evidence stating from various people that degradation is a problem on these CPUs the amount of voltage it asks for when you don't even adjust it is astronomically high it wanted one point four seven volts across all course now what's funny is when you leave it in precision boost overdrive by default and drop down to like 139 but I was able to actually under volt it back down to one point four volts and which is still fairly fairly high for all core we saw temperatures really reduced but even with the 360 AIO we were seeing temps at nine DC on water on this particular CPU in an open air test bench so you stick it in a case and you start to reduce the air flow or get any sort of recycled warm air through this through the cooler you're gonna see those temps come up and probably turn into a problem in terms of heat I am also suspecting this CPU might already be slightly degrading not that it's calling you bad names or anything like that I think it's degraded slightly I was able to get four point six five gigahertz out of all cores on less voltage and I was running four point six right now so in the full day's worth of testing and heat loading and back-to-back runs I had to drop it 50 megahertz and bump it up to clicks on the voltage button to get it to go stable again so I feel like if we were to do this for another day or two we might lose even more core clock out of it and there's people like build Zoid who's talked about the degradation of his CPU and you can just go into the AMD subreddit and you can find all kinds of stories of people's 3000 series processors no longer hitting the precision boost overdrive numbers that they were expecting to see and some of them no longer boosting at all and that's what's led a lot of the articles about whether or not the voltage out of the box on these is set way too aggressive now if you remember what that story was left off was AMD was blaming the motherboard manufacturers but then again the mother more motherboard manufacturers are like it's only giving what the CPUs asking for so there's still no definitive and nobody's really circled back it and really kind of tried to get down to the to the core of that root or that issue and we still don't know exactly what that is so that's what my recommendation quite honestly is although 500 points in Senate bench looks really nice and you were seeing significant corner our speed improvement and score improvement in things like Geekbench I don't feel that these are things you would truly notice and to be honest if you were turning and run rendering videos all day long I don't think I would want to do it at this voltage either so I would be highly concerned about degradation I'm debating on sacrificing the CPU to long term testing on degradation where we keep it overclocked and just have it doing something like folding or something that uses a high intensity workload for long periods of time and document what happens and when it happens and how much time went where this would be like probably months in the making where we say okay for this long we had to make this change and then it made a crash here and we start incrementally like adjusting it and showing you from A to Z how much changes happen so if you guys want us to make that video comment down below that you want us to make it but for the most part we saw no improvement in gaming if you got a gaming machine just leave precision boost overdrive on and call it a day the reason why you want to overclock Intel though is because the single core performance are the single core clock and the all core clock are so close to each other and they're so high versus the base clock that even when you lock all cores to the same clock speed you're still getting an extremely tangible benefit of all the you know the core speed even though the IPC sucks a little bit it's a lot simpler honestly and it doesn't require nearly as many volts to actually overclock so I showed you kind of how I did it and I showed you how far this one went and if you want to do it you assume all risk obviously on any damage you may do to your CPU and if you're anything like me you're probably gonna do it anyway probably is gonna tinker around with it and if you can if you can afford to make that sacrifice of potentially killing your CPU because once you change anything on this outside of its out of the box perimeters you assume all the responsibility for that and there's no promises as to how it's gonna do anyway that's it for today guys thanks for watching if you want to make that video like I said about long-term degradation testing I will set this up maybe we'll take some suggestions on what software you think we should run for the long-term testing to see how this does something more realistic maybe that's got some wave pattern to it not just pegged the whole time then again I guess if we want to check degradation we would want to pick it right it's like the equivalent of seeing how long an engine will last once you poke drain the oil out of it alright guys thanks for watching and as always we'll see you in the next one

Just to throw some fuel into the "rabble rabble we hate jay" dumpster fire :). He continuously refers to a CCD as a CCX (Ehh it's whatever but it doesn't make him look any smarter). He also brushed off DDR overclocking which is the easiest and most important thing to do on Zen in order to get more performance. So yea i can't take this video seriously at all.

[u/Dragonacc]

I unsubbed him a while back, I lost interest in custom water-cooling and his bias (intentional or not) turned me off.

[u/MoarCurekt]

Should be titled
"Jay demonstrates how little he knows about Ryzen overclocking, spreads misinformation, and generally fails on AMD platform"

[u/Schnopsnosn]

Jay is a clown and always has been.

He can build water cooling loops, but even there it's blatantly obvious he's playing favourites with two specific companies. See for example his review of the Corsair A500, that's been universally dunked on for good reason...

In general it's infuriating to watch him talk about something more technical because he really knows no more than the average Joe, yet has a huge subscriber base that gobble the shit up he spews and run with it.

[u/OnePieceZoro]

Reminder: This is the guy that made a tweet stating that he was considering switching his editing rig from a threadripper build to an Intel inferior one all because AMD didn't send him a free sample to review so he had to buy his own.

"What? You're not sending me free stuff? I'll use your competitor's product that's slower. That'll show you"

[u/JaggedEunuch]

Yeah watched it just before seeing this post and was just disappointed in general. It isnt that hard to set pbo on and run prime95 small fft for a while to find the voltage that the silicon seems FIT for all core high current load. Letting it run auto with higher multipliers? Thats just asking for a dead CPU.

[u/Tartooth]

He's just looking to get a media cycle in with this again. Must be bored or not getting clicks lol

[u/Salvor-H]

"There's a lot of evidence stating from various people that degradation is a problem on these CPUs. The amount of voltage it asks for when you don't even adjust it is astronomically high. It wanted 1.47v across all cores"

[u/[deleted]]

RAM overclocking is satisfying. I got a 5% performance boost from sandy bridge back in the day running 2133mhz DDR3 with the tightest possible timings.

Jay needs to get with the program
