Knowing the 7700x runs hot (by design?) made me feel a bit better but I still didn't like the 95C at max load. These settings did exactly what you said they would and I am relieved. Thank you!
Just a note, just because the Cinebench run was stable, it doesn't mean it will be stable on idle overnight. Keep that in mind if your pc randomly bluescreens or shuts down, you will want to back off that curve another 5 or so
Yup - it’s still worthwhile, but chances are fairly good it will require a little more tweaking to be stable. My 5600x benched fine at -30 all core, but would randomly restart once every thirty days, or more often with certain games that exhibit certain clock behaviors. Over time I stepped it down on some cores to - 20 before it stopped happening.
This is a good advice if done manually through BIOS. But the logic in curve optimization in ryzen Master I think handles that, since you are not undervolting really. You are telling the CPU to undervolt itself and then it does so with the amount of voltage appropriate for that load. Ryzen master has cycles of total idle and total load in the stability test during curve optimization.
@@marsovac You are doing it manually through the BIOS. You are lowering the set points of the default voltage curve lower, therefore pushing the cpu closer to instability with every negative offset point.
@@prithvib8662 from what I found with my 5800x the stability issues came up with low power/idle situations. Someone had made a script to automate running P95 on 1 core at a time which was supposed to be an effective method but takes forever. I ended up settling on -25 on most cores and -15 on a few other cores just from trial and error before I finished that scripted P95 testing so I can't say how well it works. But the standard methods weren't really helping with stability.

Those who can't hit stable -30 on all cores, can try per ccx optimization, for instance in my 7950x the cc0 can only handle -20 offset, while cc1 handles -30 comfortably.
Coming to this late but this is hands down the best video I've seen about this. There aren't enough of these types of videos out there that actually show the steps taken in such a quick and succinct way and then lay out the results so clearly. Well done man.

I’ve gone for Aorus Master which I am going to use mainly for work. When the itx boards and 3D cache CPU’s are available here in the UK, I will build a new sff gaming system.
My personal experience is the two best cores are either going to be at -5 or 0, then the rest can go way down. Reason is those two best cores are already as effecient as they get, and if you try to go much lower you run into idle crashes.
@@joelman1989 Dunno if you figured it out already - but in Ryzen Master it basically tells you in the advanced overview window which cores are the best. They're marked with a star and a grey circle respectively.
@@frogyafro Unreliable by the CPU computing wrong results, causing programs or the OS to crash, and potentially corrupting data. AMD and TSMC's process engineers think 95°C is absolutely fine for reliability, and that voltage margin less than the at-spec V/F curve is *not* fine. They can simulate and test every feature and instruction the CPU has, and many interactions between them. You can't. They can do accelerated life testing and test many samples to failure at temperatures >>95°C. You can't.
@@frogyafro There are things in the BIOS settings that can make your computer not work correctly, sometimes in ways that are hard to attribute to the BIOS setting, sometimes in ways that are intermittent to the extent that users will think programs are buggy or, "computers just crash sometimes." The BIOS settings are for advanced users who know what they are getting into and have sworn an oath not to report bugs in any software *unless* those bugs can be reproduced with everything at stock.
If you can get a -30 all core you take it. Only if that fails do you need to start doing per core as AMD chips have what I call 1 "hero" core per CCD which tends to boost much higher than the rest in single threaded workloads and you can individually decrease the curve offset on those specific cores. Happy tuning!
Tuning and testing per core is best for complete stability. When testing all core workloads, each core is not working it's hardest. Each core needs testing by itself to make sure it is stable. Then if say a game, task or even idling. You are not going to find your system crashing. My 5900x I can set -30 all core and test with cinebench with no issues. But I would occasionality see WHEA errors. Tunes per core. I do get lower cinebench numbers but 100% stable. Some of my cores are still at -30 but one is at -5.
Why the hell would other tech reviewers not advertise this and more importantly why the hell would amd not push this info out?! I was on a hard pass for ryzen 7000, but this actually Got me interested again. Great vid mate, like and sub from me!
Because they need to do their actual reviews first? they only had a few days to a week to do all the testing that needs to be for a general user experience. Optimum tech is focused on SFF builds so this would've been the first thing he went to do after the normal review stuff.
for stock performance, 20c decrease of temperatures due to %36 percent of power decrease is simply amazing. When it comes to performance per watt, zen4 is simply amazing. Thanks for sharing info.
These results are crazy for a BIOS setting adjustment. Those temperatures/voltage/power draw actually make these CPU's look attractive upgrading from AM4.
If you have the time, you can tune the voltage drop per core. It takes hours for the testing so it might not be a good idea but if you got a free afternoon, then it’s a good way to get the maximum performance boost.
@@HCGonzalezJr87 Typically it's peak clocks in light loads which becomes unstable first rather than much lower all-core clocks in heavy loads. More stressful test you run less likely it will find instability. There's tools out there to test peak clocks when tuning individual core curves like Core Cycler. Sometimes there's a bad apple or two among the cores holding back the rest. For example with my 5800X(+100MHz override) worst value is +3 and best is -25. Flat value for all cores doesn't make much sense in my case. However with 16-core ryzen per core tuning is probably too much work. With 8 or 6 cores it's fine.
@@kognak6640 With Curve Optimizer, the one or two cores that don't like offsets are usually the strongest binned & as such don't have much more leeway before instability. The reason why the 5950x & 7950x characteristically do low offsets is because they're generally binned as hell anyway being top dog silicon & the worst BoM anyway, so most of the cores plainly just undervolt worse because have an already aggressive v/f curve. Try looking at Ryzen Master to identify the best cores & see what offset ratios you currently use for those respective cores. If you stress tested correctly, they should be smaller than the rest.
I just tried this on my new 7700X that I got today and wow, yeah, it totally works. Curve set to -30, max temp at 85 C, max power at 85 W. Got through a full 10-minute Cinebench R23 multi-core run just fine, with only a minor drop in performance. Temperatures maxed out at 63 C. I'll probably be dialing back things a little bit, maybe curve at -15 and max power at 100 W, to guarantee stability and perhaps eke out a little more performance as well.
@@Vegemeister1 THIS. Cinebench is only a first blush test. I did a metric ton of tuning on my 5900x and learned the hard way that I could get some really, really sweet Cinebench runs over and over again stable but outright crash in certain games and other stress tests in minutes or an hour. Don't fall for this at face value... while it "might" be completely true a whole lot more stability testing needs to be done to prove it won't crash frequently in certain workloads and games. Curve Optimizer can leave you wondering why your system restarts once every 3 hours in a game... or once every two days... it can and will cause bizarre stability issues. Because it all revolves exactly what kind of load just happens to get placed on one of the random cores that can't handle the low voltage and high clocks. And you don't know when it will happen. You have to hammer them ALL properly to prove that EVERY core can stand up to a heavy load even when the cores around it are also hot.
Yes, I get that, which is why I said I would be dialing things back a bit. For the moment I've settled on -20 on the voltage, 85 C max temp and 110W max power. Time will tell if this is stable enough, or if it needs more tweaking. I'll be stress testing with other benchmarks to check that. My initial enthusiasm was because I was able to replicate the results from the video exactly with my run-of-the-mill 7700X, so this is not just reserved only for golden review samples.
@@Astfgl Hey. blast from the past here but how did that -20 voltage, 85 C max temp and 110W max power work out? Was thinking along the same lines and would appreciate a little hindsight from someone else

@@dmitc01 True. And depending on where you live, the 5800X3D can be had for $400 too. If you're using it pretty much just for gaming, the X3D chip looks like it will still be vying for best chip on the market even after Raptor Lake launches.
Man, I gained crazy performance on my 7600x thanks to you. I did all this before realising that my motherboard had these PBO settings ready to use 😂 I went from 92°C full load to 76, insane (-30mV, Tmax 85). I gained 800 points on cinebench and my pc is much quieter.

WOW. This fixed my only gripe with my entire build which was cpu temps. Did a -30 CO with just the 85C throttle limit and my temps dropped significantly in every game while maintaining a 19657 Cinebench score. Thanks so much!
Man, best video ever! My 7800x3d was able to handle the minus 30 and in ow2 training i went from 75 ish °c to 45 ish °c. Also cinebench socre went up by 550 points.
@frostedflinks lol, same, so what I'm gonna do is find out the tdp of the 7800x3d (I got the same cpu), lower the thermal limit as much as it can go without becoming instable based on that tdp info, and come back here and post it for yall. Let me know if ya heard of anymore pointers.
Can you please explain your TDC and edc values in bios for ryzen 7700x? TDC of 480000ma is 480A and EDC of 640000ma is 680A. These values seems too high???
I'm not upgrading this generation, but this is such a helpful video. I'm surprised AMD isn't pushing this in their marketing, because looking at those temps, I had no interest whatsoever in 7000 series and thought it was pretty lame how hot they were, but this video alone would be enough to make me buy it if I wanted to upgrade.
It's so obvious AMD are scared to see the new Intel Raptor Lake, that's why they bump clock speed at TDP like crazy which caused the CPU overheating. They know Intel going to destroy them with Raptor Lake.
Because it increases RMA rates when a bunch of users who don't know what they're doing undervolt/overclock their processor because some clown on youtube told them it was a "fix".
@@Vegemeister1 They are not only clown youtuber, they are paid AMD shills just like you can see with LinusTechTips, JayzTwoCents, GamersNexus, HardwareUnboxed and other popular TrashTuber.
This is a very good video explaining everything in detail and at the same time making it simple and easy to understand. I overclocked my ryzen 5 7600 and tested on cinebench and prime 95 and it was perfect, until it started blue screening…. I turned the over clock off and it blue screened again. I’m not sure if it’ll happen again or not but I wouldn’t recommend overclocking the 7600. It really isn’t worth it. I only got maybe 4% increase in performance but I didn’t even notice it. The cpu is really good as it is so don’t overclock even if you know what you are doing.
You definitely hit the silicon home run on your 7700X. That is an insane drop in temperatures with just a few tweaking. Definitely worth tuning that CPU.
I think this would be a fantastic selling point for AMD if the CPUs just performed like this out of the box. Seeing this performance with 60ºC and 85W matching the "by design" performance makes absolutely no sense that AMD would put out these products reaching the temperature levels they did. If we as users can do this type of tuning this easily, I feel like they could as well just make them behave like this out of the box, and allow those temperatures and power targets to act as designed for people who really would like to push they chips to the max. I know binning comes into play here, but it woudn't be necessary to achieve 60ºC @ 85W for all chips, however having them overpowered and at near TJunction at the exact same performance of what we see here is completely unacceptable. Anyway, great video as always!
As Roman Der8auer showed in his new vid even the process of delidding and direct-die-cooling 7000-chips can save you up to 15°C in difference. Imagine both! Of course the effects would be way less than both temp differences just combined but still a massive improvement that shouldnt be overlooked when comparing to intel etc
I can imagine a seriously tuned 7600X delidded and optimized in PBO2 with a beefy cooler and using per-core overclock could potentially hit something like 6GHz on the best core with the rest set to 4.5 - 5GHz. That would be nuts.
Thank you so much for this guide! I just adjusted the curve optimizer to -30 on my R5 7600x and my Cinebench R23 score increased by almost 1000, the max temp decreased from 92 to 78.4 and I think the clock speed went up from 5.4 Ghz to 5.7 the wattage dropped aswell, from 130 to 111. Thank you so much! Such an easy to understand guide.
Thank you!!!!!!!!! I was somewhat annoyed with how hot this thing ran even if AMD says it's normal. It's darn hot in Texas so less power draw and less heat in the room with similar performance is amazing!!!
I just hope we could also tweak the settings like this on the upcoming b650E,this is just a life changer for all 7000 users....power and temp drop without any performance compromise is just a big deal...just wow!!!
Should be able to, my B350 has PBO2 and all the same settings he shows in the video. I use the same curve optimizer and it works great and frequently boosts to 4648Mhz. I didn't know it allows us to set a power limit though but I'll probably skip that since my 5600X reaches 51C max already.
I've had my Ryzen 5800X for a year and had not touched PBO overclocking in that time. This video convinced me to give it a shot and your clear and concise way of communicating the topic resulted in a 250Mhz increase in all-core boost clock. Love your content, and thank you so much!
Have you tested single core stability for -30 Curve Optimizer? Because from past experience in Ryzen 5000, CO is most problematic at a single core workload because 1-core boost clock is much higher than all core boost clock and therefore, requires much more voltage. If you undervolt too much, you will experience performance degradation in single core performance, or worst case, outright crash of program's you're trying to run. Civ 6 is super sensitive to this and an unstable undervolt will cause the game to hang up frequently.
This kind of studious and meticulous work is the reason why I am subscribed to and come to this channel over and over. You are a godsend! I am looking for a completely new build after spending >10 years with an i7-2720QM laptop and AMD 7000s look very enticing. I was hoping and expecting your tuning and undervolting video and here it is! Thank you so much.
You need to run CoreCycler or OCCT in ST rotating mode to validate stability on each core at given offset. If a core fails you can back off the all-core negative offset, or switch to per-core and back off just the core that failed. Cheers.
@@LiveType Just to correct a common misconception, please see what I wrote elsewhere in this thread: > On the contrary, the best cores get an optimal curve at the factory, and applying additional negative offsets to already-optimized cores can make them unstable. You might actually need a positive offset to make your best cores stable with "AutoOC" enabled! If applying a negative offset makes your system unstable, it's probably a golden sample that's already boosting to 4.8+ GHz and should be left alone. It's likely that your launch-day 5950X was already running optimally. Sorry!
@@bambinone So the fact I can't get my 7700X to run stable at anything more than -10 is good? I thought I had one of the worst binned samples out there when everyone else can get away with -25 or more, while I can't go more than -10. It's hard to find good feedback on what is "good" for a 7700X, it'll run at 5.13ghz all-core stable just fine with the little bit of tuning I've done to it. But I don't know if that's considered excellent or what. Also paired with a 360mm AIO so I expected just the overkill cooling alone to allow it to boost beyond average.
@@JohnDoeWasntTaken not necessarily good but it's likely that one core is stuck at -10 and the other cores can take larger negative offsets. You just have to do the work to figure out which core(s) are stuck at -10 and what those larger negative offsets are for the others.
@@bambinone I already did. The two preferred cores are at -5 while the rest can do no more than -10. Believe me I've tried everything 😂 Blows my mind how badly (or good?) binned this chip is. I used OCCT to confirm stability and every core errored at -15. The all-core number I quoted is during Cinebench R23 so I score a little less than 20k with it. I'm just trying to wring this chip out as much as possible while waiting for 9800X3D
Great video, it helps a lot :-). Can you suggest also safe values in PBO for the 7950x? Not only PTT, but also TDC and EDC limits. I would only know what to set in the PPT instead of 230000 there I I would try 160000, but I have no idea about the other values. Big thank to anyone who knows what to use. Ok I think I could set the Auto option, but I would prefer to set the values manually.

Ryzen 5 7600x owner here with an MSI mobo. I followed your guide and dropped my magnitude to 25 to start and it dropped my cinebench temperatures 15C and I gained 300mhz STABLE with no crashes. Awesome video thank you!
Great video! Free performance is always nice! I don't get what is the reasoning behind saying that 95 °C or 85 °C is "uncomfortable" or "too warm" for a CPU.
What I am trying to say is: for a given undervolt + power limit, I'd rather run the cooling more silent with CPU at 95°C, because that is perfectly fine for electronics. Moreover, coolers are more efficient with higher T difference between ambient and radiator.
Silicon wasn't always this good. Temps that high would degrade the chip and lead to premature failure. So even though AMD say it's fine, a lot of people just still aren't comfortable seeing numbers that high.
AMD should be thanking you for this video, definitely going to alleviate the concerns of those who ruled these CPUs out due to their high default temps!
You forgot to mention that in PBO you can actually do per core voltage adjustments. This way you can get on average much lower voltage, since you're not limited by the worst core. You would likely get some 5-10% improvement above your setup, if not more (dependent on the sample). I've done undervolt on 5600G, and cores vary from -30 to -15.
@@motoryzen You manually check it by stability. The process isn't very complicated. 1. You test max stable undervolt for entire CPU - bifurcation method is optimal. 2. When you find stable undervolt, you test each core with undervolts - same method as before. It might take several tries to get it perfect, but the effects are amazing. Sometimes a single core can destroy undervoltability by a lot, -10 to -30 variation is normal, so I highly suggest trying all cores.
PBO cut my single core performance by 15%. Curve optimizer messed up my Windows to the point I had to reinstall... Still, thanks for trying to help I guess.
Hit 5077hz, 74 celsius on 70W. That’s crazy bro, thank you, really good guide. Thermal limit on 80 and power limit on 95 and curve optimizer on negative 20.
They can, they just did something different this generation. They went for a temp target instead of just a clock target. So no matter what, straight out of the box it tries to hit 95c, even if it doesn't need to. My only guess is they did that so that everyone gets the performance rated on the box. But as we can see here, many of these chips are not going to need to hit 95c to reach the stock clock speed.
Because letting them get hot like that means less clock variation, which means less frametime variation and microstutters. There's no point getting your CPU under 95c when the same amount of heat is released into the air anyway.
Because they want to beat intel in those benchmarks, cuz HUR DUR 1% faster than in games, so that they can raise their plattform pricing & overall sales vs Intel. Unfortunately that means we all now have to spend way more on motherboards with overengineered power delivery.
@@flake2093 the actual amount of heat is determined by the wattage, not the temperature. A 200w CPU at 50°C will still output twice as much heat as a 100w CPU at 80°C
Big warning: based on my experiences with a 5950X using curve optimiser can cause CPU calculation errors that don't cause crashes or WHEA events. Best approach is to run at least 30 minutes of Prime95 stress test (with and without AVX) without CO turned on, make sure there's no errors and then try it with CO turned on. If there are errors, reduce the offset and try again.

I ended up settling on -25 on most cores and -15 on a few other cores just from trial and error before I finished that scripted P95 testing so I can't say how well it works. But the standard methods weren't really helping with stability.

Those who can't hit stable -30 on all cores, can try per ccx optimization, for instance in my 7950x the cc0 can only handle -20 offset, while cc1 handles -30 comfortably.

Coming to this late but this is hands down the best video I've seen about this.

Undervotling is more attractive than overclocking
New future, old man!
My personal experience is the two best cores are either going to be at -5 or 0, then the rest can go way down. Reason is those two best cores are already as effecient as they get, and if you try to go much lower you run into idle crashes.
what gpu are you used?
gtx 5090
How do you figure out what your two best cores are?
@@joelman1989 Dunno if you figured it out already - but in Ryzen Master it basically tells you in the advanced overview window which cores are the best. They're marked with a star and a grey circle respectively.

Dude, this was amazing. I hope the video blows up, because everyone needs to see it, and not just those buying Zen 4.
There is also an option to do per core undervolt but it is more involved and requires more time.
You can use "all cores" and define minimum value for all core, after that use "per core", put this value, and after that, tune more precisely
this is how i have my 5800x set per core curve optimizer
If you can get a -30 all core you take it. Only if that fails do you need to start doing per core as AMD chips have what I call 1 "hero" core per CCD which tends to boost much higher than the rest in single threaded workloads and you can individually decrease the curve offset on those specific cores. Happy tuning!
Tuning and testing per core is best for complete stability. When testing all core workloads, each core is not working it's hardest. Each core needs testing by itself to make sure it is stable. Then if say a game, task or even idling. You are not going to find your system crashing.
My 5900x I can set -30 all core and test with cinebench with no issues.
But I would occasionality see WHEA errors. Tunes per core. I do get lower cinebench numbers but 100% stable.
Some of my cores are still at -30 but one is at -5.
bro your new studio/ lighting setup looks insane. Always raising the bar - love it!

I was on a hard pass for ryzen 7000, but this actually Got me interested again.
Great vid mate, like and sub from me!
I dont get this aswell. There just has to be a downside, otherwise amd would not push the temps that far. It doesnt make any sense.
Because they need to do their actual reviews first? they only had a few days to a week to do all the testing that needs to be for a general user experience.
Optimum tech is focused on SFF builds so this would've been the first thing he went to do after the normal review stuff.
@@Danieldialga The downside is that as stated in the video not all cpus can do it so they need the extra voltage for stability.

zimply amazing you mean?
These results are crazy for a BIOS setting adjustment. Those temperatures/voltage/power draw actually make these CPU's look attractive upgrading from AM4.
If you have the time, you can tune the voltage drop per core. It takes hours for the testing so it might not be a good idea but if you got a free afternoon, then it’s a good way to get the maximum performance boost.
I tried this and I thought it was stable, Cinebench was fine, but crashing in games. Went back to all core offset. Screw it. Tons of trial and error.
@@HCGonzalezJr87 Typically it's peak clocks in light loads which becomes unstable first rather than much lower all-core clocks in heavy loads. More stressful test you run less likely it will find instability. There's tools out there to test peak clocks when tuning individual core curves like Core Cycler. Sometimes there's a bad apple or two among the cores holding back the rest. For example with my 5800X(+100MHz override) worst value is +3 and best is -25. Flat value for all cores doesn't make much sense in my case. However with 16-core ryzen per core tuning is probably too much work. With 8 or 6 cores it's fine.
@@kognak6640 With Curve Optimizer, the one or two cores that don't like offsets are usually the strongest binned & as such don't have much more leeway before instability. The reason why the 5950x & 7950x characteristically do low offsets is because they're generally binned as hell anyway being top dog silicon & the worst BoM anyway, so most of the cores plainly just undervolt worse because have an already aggressive v/f curve.
Try looking at Ryzen Master to identify the best cores & see what offset ratios you currently use for those respective cores. If you stress tested correctly, they should be smaller than the rest.
@@GeneralSouthParkFan Nah, I prefer HWInfo which reports full CPPC priority order for cores.
@@kognak6640 can you share your settings if you did undervolt? Have 5700x and sff case - don't like temps being too high

Almost like overclocking is back. 200MHz is pretty big.
Except you reduce voltage instead of increasing it haha
@MAN oh, tell me about the performance, temp and power with that -40 please
I just tried this on my new 7700X that I got today and wow, yeah, it totally works. Curve set to -30, max temp at 85 C, max power at 85 W. Got through a full 10-minute Cinebench R23 multi-core run just fine, with only a minor drop in performance. Temperatures maxed out at 63 C. I'll probably be dialing back things a little bit, maybe curve at -15 and max power at 100 W, to guarantee stability and perhaps eke out a little more performance as well.
Cinebench is utterly worthless as a stability test.
@@Vegemeister1 THIS. Cinebench is only a first blush test. I did a metric ton of tuning on my 5900x and learned the hard way that I could get some really, really sweet Cinebench runs over and over again stable but outright crash in certain games and other stress tests in minutes or an hour. Don't fall for this at face value... while it "might" be completely true a whole lot more stability testing needs to be done to prove it won't crash frequently in certain workloads and games. Curve Optimizer can leave you wondering why your system restarts once every 3 hours in a game... or once every two days... it can and will cause bizarre stability issues. Because it all revolves exactly what kind of load just happens to get placed on one of the random cores that can't handle the low voltage and high clocks. And you don't know when it will happen. You have to hammer them ALL properly to prove that EVERY core can stand up to a heavy load even when the cores around it are also hot.
Yes, I get that, which is why I said I would be dialing things back a bit. For the moment I've settled on -20 on the voltage, 85 C max temp and 110W max power. Time will tell if this is stable enough, or if it needs more tweaking. I'll be stress testing with other benchmarks to check that. My initial enthusiasm was because I was able to replicate the results from the video exactly with my run-of-the-mill 7700X, so this is not just reserved only for golden review samples.
@@Astfgl Hey. blast from the past here but how did that -20 voltage, 85 C max temp and 110W max power work out? Was thinking along the same lines and would appreciate a little hindsight from someone else

5900X would be an excellent upgrade. You can use the same board and just get great performance for under $400
@@dmitc01 True. And depending on where you live, the 5800X3D can be had for $400 too. If you're using it pretty much just for gaming, the X3D chip looks like it will still be vying for best chip on the market even after Raptor Lake launches.
Would be silly not to, may as well wait for the 7800X3D too.

6:20 Literally said "look at that!" out loud. Really appreciate the comparisons and having the Intel for context
I'm not upgrading this generation, but this is such a helpful video. I'm surprised AMD isn't pushing this in their marketing, because looking at those temps, I had no interest whatsoever in 7000 series and thought it was pretty lame how hot they were, but this video alone would be enough to make me buy it if I wanted to upgrade.
they did show in their marketing efficiency gains at lower power levels (they themselves stated something like 70% gain at 65W)
It's so obvious AMD are scared to see the new Intel Raptor Lake, that's why they bump clock speed at TDP like crazy which caused the CPU overheating. They know Intel going to destroy them with Raptor Lake.
Because it increases RMA rates when a bunch of users who don't know what they're doing undervolt/overclock their processor because some clown on youtube told them it was a "fix".

Pretty incredible performance while lowering power consumption and heat by allot.
This is a very good video explaining everything in detail and at the same time making it simple and easy to understand.

I’m not sure if it’ll happen again or not but I wouldn’t recommend overclocking the 7600. It really isn’t worth it. I only got maybe 4% increase in performance but I didn’t even notice it. The cpu is really good as it is so don’t overclock even if you know what you are doing.

Love the thumbnail! Very simple yet effective
I think this would be a fantastic selling point for AMD if the CPUs just performed like this out of the box. Seeing this performance with 60ºC and 85W matching the "by design" performance makes absolutely no sense that AMD would put out these products reaching the temperature levels they did. If we as users can do this type of tuning this easily, I feel like they could as well just make them behave like this out of the box, and allow those temperatures and power targets to act as designed for people who really would like to push they chips to the max. I know binning comes into play here, but it woudn't be necessary to achieve 60ºC @ 85W for all chips, however having them overpowered and at near TJunction at the exact same performance of what we see here is completely unacceptable.
Anyway, great video as always!
Awesome video!!! Everyone that is using a 7000 series should watch this
As Roman Der8auer showed in his new vid even the process of delidding and direct-die-cooling 7000-chips can save you up to 15°C in difference. Imagine both! Of course the effects would be way less than both temp differences just combined but still a massive improvement that shouldnt be overlooked when comparing to intel etc
I can imagine a seriously tuned 7600X delidded and optimized in PBO2 with a beefy cooler and using per-core overclock could potentially hit something like 6GHz on the best core with the rest set to 4.5 - 5GHz.
That would be nuts.
Wow such a simple and clear video. Nice job. You made making bios changes for clear gains so straightforward
It's incredible!
What's not though is the value of Zen 4, the value is just not there specially 7600X and 7700X( Raptor Lake might win here).

guaranteed clock stretching 💀
@@whoisthatthingwhat The gain is at the effective clock under load not the displayed max value.
Have you tested single core stability for -30 Curve Optimizer? Because from past experience in Ryzen 5000, CO is most problematic at a single core workload because 1-core boost clock is much higher than all core boost clock and therefore, requires much more voltage. If you undervolt too much, you will experience performance degradation in single core performance, or worst case, outright crash of program's you're trying to run. Civ 6 is super sensitive to this and an unstable undervolt will cause the game to hang up frequently.

You need to run CoreCycler or OCCT in ST rotating mode to validate stability on each core at given offset. If a core fails you can back off the all-core negative offset, or switch to per-core and back off just the core that failed. Cheers.
@@LiveType Just to correct a common misconception, please see what I wrote elsewhere in this thread:
> On the contrary, the best cores get an optimal curve at the factory, and applying additional negative offsets to already-optimized cores can make them unstable. You might actually need a positive offset to make your best cores stable with "AutoOC" enabled! If applying a negative offset makes your system unstable, it's probably a golden sample that's already boosting to 4.8+ GHz and should be left alone.
It's likely that your launch-day 5950X was already running optimally. Sorry!
@@bambinone So the fact I can't get my 7700X to run stable at anything more than -10 is good? I thought I had one of the worst binned samples out there when everyone else can get away with -25 or more, while I can't go more than -10. It's hard to find good feedback on what is "good" for a 7700X, it'll run at 5.13ghz all-core stable just fine with the little bit of tuning I've done to it. But I don't know if that's considered excellent or what. Also paired with a 360mm AIO so I expected just the overkill cooling alone to allow it to boost beyond average.
@@JohnDoeWasntTaken not necessarily good but it's likely that one core is stuck at -10 and the other cores can take larger negative offsets. You just have to do the work to figure out which core(s) are stuck at -10 and what those larger negative offsets are for the others.

Have you found good value to drop the temps? My 7950x is running hot and I don't really care about performance drops.
IMPRESSIVE been looking at thermals (7000 series) the last couple of days and you are the first I've seen to present what seems to be a solution... AMDs "it's meant to run at 95C" and their assertion that it would not lead to degradation was not palatable. (maybe it's true it just makes me uncomfortable). Thank you. Nice work.
WARNING: Do not attempt (aggressive) undervolting with an older and/or budget PSU that doesn't specifically mention having UVP (undervolting protection). You can fry your CPU in that scenario.
T. Fried a Ryzen 7 2700X by setting the max negative offset (-0.3V) on a Gigabyte B450 Aorus Elite powered by a Seasonic M620

I don't get what is the reasoning behind saying that 95 °C or 85 °C is "uncomfortable" or "too warm" for a CPU.
Its not like youll hit those temps daily either unless your pc is just doing 24/7 cinebench runs
What I am trying to say is: for a given undervolt + power limit, I'd rather run the cooling more silent with CPU at 95°C, because that is perfectly fine for electronics. Moreover, coolers are more efficient with higher T difference between ambient and radiator.
thermal cycling usually degrades cpus in the long run
@@slywolf_ agree
EDIT: But even then, it would still be perfectly ok
Silicon wasn't always this good. Temps that high would degrade the chip and lead to premature failure. So even though AMD say it's fine, a lot of people just still aren't comfortable seeing numbers that high.
I already thought about undervolting but this is even better
AMD should be thanking you for this video, definitely going to alleviate the concerns of those who ruled these CPUs out due to their high default temps!
Now they can just rule them out because of components cost and water cooling.
PC was shutting off during some games, Temps were getting over 112 in this cpu. This video has me running so cool now. Life saver.
You forgot to mention that in PBO you can actually do per core voltage adjustments.
This way you can get on average much lower voltage, since you're not limited by the worst core.
You would likely get some 5-10% improvement above your setup, if not more (dependent on the sample).
I've done undervolt on 5600G, and cores vary from -30 to -15.
but how would you know which core needs a different voltage versus other cores?...that is the part I don't recall anyone ever answering
@@motoryzen You manually check it by stability. The process isn't very complicated.
1. You test max stable undervolt for entire CPU - bifurcation method is optimal.
2. When you find stable undervolt, you test each core with undervolts - same method as before.
It might take several tries to get it perfect, but the effects are amazing.
Sometimes a single core can destroy undervoltability by a lot, -10 to -30 variation is normal, so I highly suggest trying all cores.
@@michahalczuk9071 ok so it's pretty much as I already figured how it would work.
I thought you were going to tell me something different. (Shrugs)
@@motoryzenPrime95 gives you per core stability readout, so if you are very careful you can undervolt all at once and check which are unstable.
@@michahalczuk9071 now THAT...I forgot about.m..ok right on
I went from 95C to 60C RUNNING CYBERPUNK. Youre goated.
PBO cut my single core performance by 15%.
Curve optimizer messed up my Windows to the point I had to reinstall...
Still, thanks for trying to help I guess.
Hit 5077hz, 74 celsius on 70W. That’s crazy bro, thank you, really good guide. Thermal limit on 80 and power limit on 95 and curve optimizer on negative 20.
makes you wonder why they cant just make them cooler out of the box 🤨
They can, they just did something different this generation. They went for a temp target instead of just a clock target. So no matter what, straight out of the box it tries to hit 95c, even if it doesn't need to. My only guess is they did that so that everyone gets the performance rated on the box. But as we can see here, many of these chips are not going to need to hit 95c to reach the stock clock speed.
Because letting them get hot like that means less clock variation, which means less frametime variation and microstutters.
There's no point getting your CPU under 95c when the same amount of heat is released into the air anyway.
@@Jonathan-fw6ty wont it generate less heat?
Because they want to beat intel in those benchmarks, cuz HUR DUR 1% faster than in games, so that they can raise their plattform pricing & overall sales vs Intel. Unfortunately that means we all now have to spend way more on motherboards with overengineered power delivery.
@@flake2093 the actual amount of heat is determined by the wattage, not the temperature. A 200w CPU at 50°C will still output twice as much heat as a 100w CPU at 80°C
This was good to see. Nice video, thank you for making it.
4:56 In PBO Limits manual mode, how we set PPT, TDC and EDC ratio? Is there a formula?
Idk I have same problem
Useful notes, cheers! Saw huge temp drops at no significant performance loss.
Big warning: based on my experiences with a 5950X using curve optimiser can cause CPU calculation errors that don't cause crashes or WHEA events. Best approach is to run at least 30 minutes of Prime95 stress test (with and without AVX) without CO turned on, make sure there's no errors and then try it with CO turned on. If there are errors, reduce the offset and try again.
Top notch video and nuts results!
I knew that you'd be the one to do this properly, Jay just gave up and put a AC to it.
come on, that took a lot of work... as well as a lot of tape and cardboard
Why you even watching him? He started so much drama with his “Get out and buy Nvidia cards now” video. Then when everyone called him out he called everyone “idiots”, and dense and ignorant if they didn’t listen to him. Then he made a non apology video where he ignored his behaviour and only sort of walked back his comments. And just today JonyGuru had to make a video because he created drama around the new cables for GPUs. He’s genuinely one of the worst tech channels on RUclips.
This is why I've been subbed for years.
Hey there, I tried doing the precision boost overdrive starting at 30 and now I can’t boot into windows. I’ve reset all bios settings to default and every time is starts up with goes into automatic repair and then said “Your PC did not start correctly”. Any and all help is greatly appreciated, I just built this and prior to changing PBO settings it was running fine, just hitting the 95* mark and wanted to change that.
Hey friend, sorry that I don't have any advice to help. Were you able to sort out the issue? Another user above you said that they had to reinstall Windows.
I wish I had subscribed to this channel sooner, incredible practical way to present the settings without losing hours of our lives and keeping the subject and going straight at it! Awesome presentation!
Need 7800x3d update
should be exactly the same
@@raytek8837 I tried with pbo -30 but if I put a 60w limit it lowers the degrees to 100% but in game I have a strange behavior of the cpu, almost 100% on some games
@Luca-ij2xe where you evere able to figure ir out?
Using the 7800x3D in a velka 3 using only a NH-L9A AM5. I was hitting 77c at idle - min load, now I hit 56c idle and max temps of 80 at load. Very little drop in performance. Incredible underclock.
Negative curve set to “30”
PBO at “80w” Thermal throttle “80”
Magnificent drops in thermals
Turns a spooky temp’d hot box into one of the most powerful, portable PC’s in the world 😎
brilliant video/tutorial !
