Hey Everyone I am glad this video has been helpful to everyone - I haven't found the time to post anything more yet this year even though I had every intention of doing so. I appreciate all the subs and I will post another video once I find the time!

[@Rico_______]

Thank you for the excellent video! I have one question, though: CPU performance also includes your RAM, correct? Your performance seems very good. What RAM did you use?

[@bosmang1]

Wow those are high r23 scores for a 5800x mine only gets to 15749 how my ppt is 126, TDC 85 EDC 155 how come my EDC runs so high I set it to that but only Becuase if where the performance lies. Am I missing something I did this when I was new to overclocking so maybe I’m missing something

[@TheRealSteviee]

@@bosmang1 im running a 5800x and it doesnt like when i play with it very much in PBO and curve opt. it seems to run best on optimized defaults, PBO disabled and XMP 1 at just the two simple entries of 4.5ghz @ 1.15v. If I run stock voltage it'll smack 100c like it owes it money, even with a very robust custom loop setup...I get a CBR23 multi of about 15800 with just the two settings i previously mentioned. I am getting ready to try your methods. I hope this video saved my ass because I was about to throw it out the window. Thank you!

[@gunnarthegumbootguy7909]

Really found it useful I was messing around with pbo in ryzen master before but i wasn't really sure what i was doing... i've noticed that after i set the curves to -24 to -30 (depending on core), I also set the cpu voltage setting offset to -0.5 v and that helps a lot with performance... Also most stress tests, benchmarking software, games, get absolutely no errors even when i set all cores to -30, but there is one single game that for some reason reacts badly and starts crashing: red dead redemption 2.... really everything else works great, even running stress tests for hours on end, i wonder if it accesses the cpu in some unusual way if that is even possible? it typically only has about 15-25% cpu use in game according to rivatuner. Really that single application is the only reason i don't just set all cores to -30 and +125 MHz extra on pbo, instead doing -24 on the two most problematic cores and then -27 to -30 on the rest and "only" +100 MHz (this is on a 5600x so it's still pretty satisfying increase) also I set the per core voltage in ryzen master to just 0.79375.... this works very well with the curves set this low... I find that setting the EDC to 119-124 is about the best for 5600x too for heavy multicore stuff and benchmarks like cinebench20, but i think for real world things, for gaming and such where you are not maxing out the cpu, maybe it's better to set it to something like 115 to keep the most busy cores going at maximum clockspeeds which i suspect is better for gaming performance, really for those situations i think you would hope the EDC and TDC limits are not even met at all...

Wow, I always thought PBO was cool but after watching your video and playing around with the per core curve optimizer, I got a solid 12% performance bump over stock settings. All while getting lower idle temps. This was a game changer. Also, the BIOS update that I needed for this had AGESA 1.2.0.0 and I was able to run my Infinity Clock at 2000MHz at 1:1:1 with some DDR4-4000 RAM. System has never run so well!

[@CognizantCheddar]

Great guide. One tip to add: CPU Load Line Calibration in your BIOS can do a lot to stabilize more aggressive Curve Optimizer offsets. e.g. The two best cores on my 5900x are capable of much better offsets if I change LLC from "auto" to "level 3" on my Asus motherboard. Just don't set the LLC too high -- voltage overshooting can degrade your CPU. You can google recommended LLC levels for the various motherboard brands. Generally a medium setting is best.

[@sangsangsang25]

thanks, i manage to get the best settings with my new 7900x also pbo per cores with llc lvl 3 really goes well together

[@Viking8888]

I just bought my first Ryzen CPU about a month ago. Bought an Asus ROG Crosshair VIII Hero board to pair it with. I kind of feel like a chunk of the last 22 years of being in the tech industry just disappeared from my brain and I went back to being a novice. There are so many settings I have never heard of in my UEFI that I just set it all to Auto and went on my merry way. But, and this is a HUGE but.....Temps on my R7 5800X have been volcanic at times. I'm definitely going to follow your video to get the best performance to temperature ratio I can. Thanks for the time you put into it, I appreciate it.

Great video man, thanks for putting in the time and the effort! This link will be a reference for many! Ryzen 3 owners, including myself, have been scouring YT to find a decent guide for this since it was announced and there was nothing so detailed. Optimum Tech did something relatively basic (plus he had a very good chip that could do -30 out of the box). I appreciate the tip on how to find the failing core through CPUZ and the motherboard PBO limit for us with dual CCD 5800X’s (you didn’t explain why though). I had to do the OCCT - Small Data Set - SSE- Thread count 1 affinity method for one core at a time to find my best values and kept notes on an excel sheet and ended up with 30-30-10*-22-10-30-30-10*. I haven’t tinkered with the power limits much though and I would like to lower my temps even more and this motivated me to get back to it even though the gains are minimal for gaming. We do it cause we like tinkering and hopefully it will make our setup more efficient. It would be great if you could share your excel online, I’d love to use your template.

[@paulantong]

I stumbled upon this video while researching why my 5900x is throwing WHEA errors with no BIOS modification. I found several topics online suggesting that a positive curve optimizer change of the faulty core fixes this problem. Indeed, it does fix it, no more WHEA errors when boosting a single core to the max. However, since overvolting might reduce the longevity of the core and you state in the video start one shouldn't put in positive numbers, what's your stance on this topic, why does this fix the WHEA errors and what are the downfalls, besides a small performance hit?

[@LuxLikeGaming]

Is anyone else watching this, knowing they most likely wont do any of it apart of a casual curve optimizer? :D But it's a great tutorial/guide anyhow, maybe I'll come back to it at a later time once the stock performance isnt cutting it anymore or I gain enough confidence to actually tinker with more advanced things than simple multipliers and the curve optimizer xD

[@Magnimodie]

I want to let you know that your video helped me over clock and diagnose my 5950x overclock super well. It's been a couple months but recently I've started crashing due to CPU and I tried looking for the WHEA errors in the event log, however, nothing WHEA related shows up, not a single one.

I don't know, but I would say if it doesn't crash then you should be alright. However I'd definitely rune Cinebench R20 and also something like 3DMark Time Spy. But really if it crashes just check event viewer's log for a WHEA error see if ones listed then decrease the undervolt on that core. However it there is no WHEA error then I'd just lower the undervolt on each core see if that helps. Probably better ways

[@pawnipt]

Thanks for sharing your findings on ryzen 5000 overclocking, it has been a big help for getting my 5800x finely tuned. I do have a tip of my own also and that is to use CoreCycler to testing core stability quickly. Set each core test to 1 minute and also define which cores are tested first in order to quickly sort out stability for specific cores after changing the curve on them. Then after all cores are set do a 6 minute test per core to be sure.

You explain things clearly. Not as common as you might think. Great guide, and I hope you make more. Subbed.

[@stopndrop4588]

This is the best explanation on the web. Thank you man.

[@jonykapa]

Hey man, great video, very clear and helpful. One thing I have to point out is that I can achieve better results controlling the temperature by limiting the PPT instead of the EDC. By that I mean leaving the EDC very high and turning down the PPT limit. I can have my 5600X achieving better results (at least on CB23) with lower PPT limit than with lower EDC limits, maintaining the same temperatures between this two different approaches. Might be different from chip to chip but thought you'd might find it interesting.

[@bosmang1]

This is similar to what I present in the video. The idea is you find your best performance with EDC and then use TDC to lower temperatures. This will overall give you higher performance per delta T than just lowering EDC. You on the other hand used PPT which in turn is most likely lowering TDC but I can't say for certain because I use TDC to tune for temps and leave PPT to be whatever it ends up being based on the EDC and TDC.

[@AV-dk7pf]

Thank you. This helped be sort out whea 18 crashes on my 5950 by setting +5 on the fastest core that was getting reported in the event viewer.

I had to reduce the PPT to 109 to get the temps in line. Cinebench r23 runs 14,800 at 78C whereas before it was doing 14,800 at 86C. If there is any way to get close to your Cinebench score without going over 80C then this is truly amazing for me.

The temperatures are in there, look at the graphs he calls "delta temperatures vs EDC" and "delta temperatures vs TDC". Those are degrees over ambient. It doesn't matter if your CPU hits 80 degrees C and his hits 85 if you're in a 15 degree room and he's in a 30 degree room, those are totally different baselines. Delta-T eliminates this.

Nice to see such clear and concise discussion without the hyperbole that so many seem to include in videos. Hope to see your following grow and recognition for your efforts :). I noted a bit of discussion around crashes occurring at idle when fairly aggressive undervolting is in place. A suggestion was to increase the base CPU voltage slightly, and then maintain a high offset in the curve settings which seems to work. THoughts? RAM Overclocking will be the next effort. Got a guide coming on that? :D

[@deloford]

Thanks for the very clear guide, the key part for me was adjusting the curve down to 5/10 for my best and 2nd best COREs on my 5950x. I still only get 28100 and 1465 with your ECP/PPT settings so not sure how you are getting 10% more performance! Any ideas? RAM over clocking maybe? Could you share your other BIOS settings?

[@DrizztDC]

I'm not 100% sure but from what I understand, no two cards are the same. Settings for his card will be different from yours due to the "silicone lottery". That is what I've read and understand about tuning a cpu.

Amazing guide man. Was able to get -30 on all cores of my 5800x except Core 2, which I got stable at -10. Also, added 125mhz. Rock solid stable on OCCT, Prime95, and UserBenchmark. Thanks for posting this!

[@Roalethiago]

Mee too, i thought i was doing something wrong when i saw people saing -30 was not possible all core but i got it, -30all core +100mhz. but, due to thermal constrains i have to really lower the edc that is around 130A tdc is 90A and ppt 125W i get a bit over 4.6 o r23, and 4950 boost in games. May i ask, what is your EDC TDC and PPT?

[@dreamdenizen]

@@Roalethiago I actually switched to a B550 board and haven't messed with it again. It's still at default. I might give it a try this weekend.

[@Frej84]

Excellent video. This is the best guide on this topic I've read and seen by far.

[@magicaces13]

Thank you I've been looking for a guide like this for my 5800x which is running at 80-90c under all core load! But coming from Intel CPUs I had no idea why it was like that or what PB, PBO2 and curve optimizer were! Very well explained and now I can get to work on mine to get the temps down and fine tune the performance. I find it odd AMD say let it go to 90c and all is fine even if its wasting power it doesn't need.

[@jay.a]

Great video! Just wanted to add that you can use a program called y-cruncher to determine which core is unstable. It has a Component Stress Tester (option 1 when you run it as is) that runs a series of tests until an error is encountered, in which case it usually tells you which logical core caused the error. Just take note that the tests will really work your CPU to its thermal limits (90 degC for my 5800x).

[@wakegary]

Holy crap you're right. I cooked 6 eggs on my tower roof. Y cruncher is neat

[@Gyneco-Phobia]

Curve optmizer at negative 25 also reduced the usual 1.375V for max clocks down to 1.212V for the same clocks.

[@alectrachtman1375]

Best guide out there. Subscribed.

[@skylerfurstonberg9506]

Best guide I've found. Thank you so much for breaking it down

[@kirk1240]

Wow good info, I just set my 5800x to -15 across the board with +200mhz, -20 caused some instability. But maybe I should try per core and reduce the boost.

[@JBR_1995]

Hey are you still using these setting right now? I also got a 5800X and wanted to play with the CO etc. to get my temps down. :) I have a bequiet! Dark Rock 4 and the processor hits the 90 C limit during CB23. During the test with 100% fan speed it's still running all cores at 4.57 GHz so it's quite impressive that the cooler manages such high clock speeds during CB23.

[@tfsweet]

Stellar video!!!! Well thought out and easy to understand.

[@keepcalm1182]

May I ask for your opinion on effective clocks: in heavy workloads (like CB) the effective clock is similar to the set Frequency, but if you for example have a lighter workload (like gaming) the effective clock is way lower then your possible max boost Frequency.. what does that mean? And why ist that the case... (Is it "wrong" to look them up maybe?:)

[@mileskg21]

this guide saved my butt and got me 5ghz on my 5800x :) thank you brother

[@PonyDude186]

Extremely informative. Just got a 5800x and want to see the capabilities of PBO 2. There's lot's of information and input from other people out there about this, but your information gave me the confidence to go ahead and test with PBO. Thanks!

[@EvolutionGaz]

Great video dude this is the best video explaining PBO2 iv found on KZbin keep the great videos coming, you have a Sub from me.
