@@TechHunterOfficial except for the fact that this guide along with the last one he made, leaves you with an unstable OC. The guy with the phone maybe right. It would certainly be in this case. This is one of the worst guides out there.

[@EndstyleGG]

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

[@essenceofsias]

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.

[@prithvib8662]

Yep. Use more advanced testing tools like Prime95 or YCruncher or something easier like OCCT to actually make sure it's stable

[@marsovac]

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.

[@EndstyleGG]

@@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.

[@realbadtech9318]

@@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.

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

[@rgscomputers1]

this is how i have my 5800x set per core curve optimizer

[@madpear]

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!

[@AnthonyTeasdale]

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.

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.

[@kognak6640]

@@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.

[@GeneralSouthParkFan]

​@@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.

[@pottingsoil723]

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.

[@Astfgl]

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]

Cinebench is utterly worthless as a stability test.

[@advil000]

@@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.

[@Astfgl]

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.

[@LBenn302]

[@ruicastro1410]

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.

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]

This. You need to test each core in the higher clock speed range and set the problem ones to -5 or 0. I spent so long tuning pbo on a launch day 5950x. Even a -5 all core offset would end up crashing doing Windows I/O nonsense or opening chrome. Benchmarks stable all day. I got a newer chip and slapped a -30 offset and it works. Not a single crash or headache. It all depends on silicon quality.

[@bambinone]

@@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!

Thank you so much! Such an easy to understand guide.

What cooling do you use?

@@actuaIpotato If you are still around, Could you tell me your vaules of PPT, TDC and EDC? I too use 7600x and its stable at -30 Curve optimiser.

[@dustinr.3507]

@actualpotato what were your values for PPT, TDC and EDC? I'm running the 7600x and that's all I need to know to fully optimize the cpu :)

[@Abra.J.]

Would like to know those values as well

[@twinjuke]

Still one of the best channels in this topic out there. Keep up this great work man!

[@techgirl517]

Thanks so much for this easy guide Optimum Tech, i applied this settings on my new AMD 7800X3D and it works very very well.

[@Fate025]

Wow pretty mind blowing, NONE of the other big review channels have probably even thought of doing such tuning to reduce temperatures. This is actually a HUGE deal cause Ryzen 7000 buyers can use their existing cooling, or save money on cooling. Otherwise they would be forced to buy 360mm AIOs or even splurge on custom watercooling.

[@tdrm]

Not ture, Ryzen 7000 runs at 95 even with the shittiest cooler, it won't overheat.

[@Fate025]

@@tdrm True, but u can check out paul's hardware's latest video where he tests old ryzen stock coolers on the 7600x. Without PBO tuning the freq drops 200-400mhz, lowering cinebench scores. With PBO tuning the clock speeds and cinebench scores get even better than with a 360mm AIO on stock untuned. So PBO tuning is definitely a must do for anyone who knows how to do it, in order to maximise performance and lower temps.

[@iliaskapatos]

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.

[@flyinggecko3322]

Hello, I have been looking for the same. Did you find an answer somewhere? Much appreciated!

[@maxvlaarhoven]

Have you found good value to drop the temps? My 7950x is running hot and I don't really care about performance drops.

[@jammuu]

Best video on this topic ever. I did everything in this video and my 7700x is straight gas now. Thank you!

[@seyahtan24]

Thank you again for helping me understand undervolting. Helped a lot with my 5600x.

[@Shabanezloth]

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.

[@GewelReal]

they did show in their marketing efficiency gains at lower power levels (they themselves stated something like 70% gain at 65W)

[@runninginthe90s75]

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.

[@Vegemeister1]

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".

[@akhilmanjunath1406]

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???

[@WhiteWolfTechGaming]

incredibly concise and easily understandable! awesome video, as usual!

[@Shise-]

Thanks for this video. Made my 7900x clock the same but at 20c lower temp and less watts! Amazing tweak.

[@sonegokrone]

In other reviews I saw this config for Eco Mode for the 7700X - PPT 88000, TDC 75000, EDC to 150000. Why are your TDC and EDC so high?

[@dianpan4922]

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.

[@jaredstewmelt]

Well done on this content! This is exactly what folks who want to keep their cooling solutions simple need to know. Air cooling isn't dead yet, y'all!

[@Trieclipse]

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!

[@whoisthatthingwhat]

[@Trieclipse]

@@whoisthatthingwhat The gain is at the effective clock under load not the displayed max value.

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.

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.

[@NootNoot.]

Although these processors should just "work" out of the box, I would love to see more tech tubers educate consumers on how to get the most out of their CPUs. While the headlines for these cpus are "hot and power hungry", it would do good to settle expectations, rather than repeat what the crowd is saying. Same goes for Intel as well. All of these higher ceilings for power draw and heat are only to reach peak performance for a set amount of time to get the highest number for benchmarks. While in fact, there's a lot more headroom for balancing performance and power/heat. It's just a bit more involved for the consumer, and exposure unfortunately has to come from influencers/journalists.
