great guide as usual. I'll be upgrading to a 9950X from 5950X sometime early next year and look forward to tinkering.

Tremendous work! I've just got my 9950x a few days ago and I'm trying to set aside some time to tune it properly. Your OC deep dives are very helpful and I'll be referencing it in my attempts. I've got the same mobo too! :D

CS was quite simple, I thought it could be changed along every point. Perhaps per core CO is still on the table :) will be waiting.

[@SkatterBencher]

CO for rough tuning, CS for fine-tuning

[@probablygrim]

Cheers for this, Gives me something to compare to with my 9900x, I'd like to think having just 6 cores per CCD may give me just a little extra thermal headroom when its boosting up. Keep up the good work :)

[@MillisecondFalcon]

Are there many benchmarks that run on Linux as well as Windows? It would be interesting to see if there's still as big of a performance difference between the OSs as was reported early after the release. I think we could see an increase in numbers of people migrating to Linux in the near future because of things like Copilot and Recall. I'm sure all the unnecessary background and idle tasks running constantly in Windows must have a negative effect on benchmarks.

My alltime fav stability test is running ycruncher v3 + small while having bf2042 open on a 128 player map while a single core game also is in use and then having 50 tabs open in Firefox and switch between programms and introduce max stress. -20 curve on some cores was stable with stress test but after this setup it crashes firefox tabs or bf2042 , now on -5 and -10 or 0 on weak cores

[@iLegionaire3755]

Is a 6 GHZ all core 9950X possible Skatterbencher? Probably need a water block, DELTA TEC 2 Quantum custom loop water cooling solution, proper deliding of the 9950X processor, direct to die, or LN2. Phenomenal work as always regardless, 5.90 GHZ if its all core is impressive regardless!

[@2Fingz75]

All core impossible with pbo cause the ccd2 will block you , with ln2/dice maybe possible

[@Crossfire2003]

The only thing I'd add to this OC is a thermal throttling temperature value (I've set mine at 82°C).

[@chlbrn]

Cool dude, I just ordered a 9950x yesterday and I can't wait to have it in my hands. Another thing in my mind is that if we disable one CCD of 9950x, can we boost another CCD even more?

Do you have any tips for memory ocing for 4x DR/32gb sticks on this platform?

[@nicolasr.5870]

Insane quality tutorial, thank you very much, but ... by the past you posted 7950X + Gigabyte, now you seemed to go to Asus. I surendered with my Asus because of too many problem with Intel LAN chip so I am now back with Aorus Extreme with Marvell and everything is fine. Would it be possible you post a 9950X + Aorus Extrem guide ? Kindly greetings There's no Expo2 tuning mode on Gigabyte, how do I translate it ? Just saw Expo 1/2 on DDR5 setting

[@SkatterBencher]

I'll consider trying another vendor for other Ryzen 9000 guides. Unfortunately my good contact at Gigabyte left so it's a lot more difficult to get answers if I have any overclocking questions (which I have, a lot). That's why I stick with ASUS this generation.

The most likely issue is too aggressive Curve Optimizer, so I would first reduce the negative CO

Hey, awesome video. I did everything and I’m scoring 40382 on cinebench and passing all the stability test. That being said I’m having hight temps about 95c full load, idles about 50c and regular gaming about 70-80s. Any suggestions? I have the lianlancool216 and I’m running Nzxt kraken z63 280mm

[@SkatterBencher]

That sounds about right temp-wise. There's two options: 1) Set the TjMax yourself in the BIOS. 2) Check what's the PPT in full load scenario and reduce it by 10% in the BIOS. Both approaches will give you lower temps under full load.

[@renny_est]

[@RockRocky09]

I have the Kingston DDR5 Kit ( PN KF564C32BBEAK2-64) and I set per your recommendations and while the +200 in boost clock was not stable, things seemed mostly fine for a few days including ram stress tests... I just adjusted my settings to be TRAS back to default of 80 instead of 38, and set DDR5 frequency at 4000mhz as a temporary test... do you have any advice? all other settings per your video are the same for my setup running an ASUS ITX board with a 9950X. thanks in advance if you are able to help!

[@RockRocky09]

Seems stable with above, now testing with looser mem timings at 6200 mhz. is also stable I will tighten memory timings and see if perhaps the large capacity IC are more sensitive and more difficult to run 6200mhz AND tight factory timings.. even though it should run 32-39-39 TRAS 38 may not be stable... we shall see

[@ProVishGaming]

So the 9950x does have good overclocking headroom, just like my 13600k. Perhaps AMD wanted to play safe after Intel pushed the limits of the i7s and the i9s.

[@progamer0256]

is it possible to run 192gb of ram at 5900hz with 9950x ? i want to build my pc to process large data faster

[@Montieyt]

Just picked up a 9950x with X670e motherboard, this is my 1st Amd CPU in 20 years, just moved from the 14900K. Anyways it seems that overclocking the 9950x doesn’t seem to improve much? Not complaining about the few % increase, but at the cost of more power and heat, doesn’t seem to be worth it, What do you guys think?

[@PuneetGupta724]

Hi what was tour agesa version while overclocking? Will these work on latest agesa 1.2.0.2 with tdp boost

[@Plermpel]

Dude I love you! This is the best Overclocking video I've ever seen. Built my system with the 9950X two days ago and spent the whole weakend tweaking my memory, but I tuned it for 6000Mhz since I read it was the best frequency. How much does the actual memory frequency affect performance, For example would 6400 CL30 be better than 6000 CL26, than I would need to spent another 20 hours on memory tweaking that's exhausting.

[@SkatterBencher]

I don't expect huge differences in real-world scenarios like games, but from the benchmark results it appears memory tuning does provide extra "oompf". The performance is not tucked away in the primary timings but rather in the unoptimized secondary and tertiary timings. That's why I usually leave the primaries at EXPO and use the memory preset to tune the sub-timings.

[@trieunguyen5897]

I’m pretty new to this, my question are these methods you shown better results performance than the Ryzen Master curve optimizer software? Thank you

[@SkatterBencher]

I only tried the Ryzen Master Curve Optimizer software once - with a Ryzen Threadripper 7000 - and it didn't give satisfactory results. So I prefer sticking with manual optimization.

[@Chicken-o5e]

I have 9950x with 360mm aio and i accidentally overvolted to constant 1.35 volts and underclocked to 5.1ghz bcuz im just testing things learning on my own tuning. I benchmarked in cinebench 23 and hit 103c with average 96c. The max safe temp advertised for this cpu was 95c. Now im panicking over my cpu already having degradation by the first week using it. I undid everything and now my cpu doesnt go above 75c stress test with auto clockspeed & voltage on with pbo on 150mhz+ and curve optimizer and shape manually tuned. But now my cpu goes upto around 1.4 volts while idle. Is this bad? Is my cpu damaged and how can i tell if it is? I want to prevent further degradation if so. Ive tried searching many forums but nobody has clear answers. Thanks for any help❤

[@SkatterBencher]

Your CPU is not damaged and 1.4V idle on desktop is normal. It's boosting to 1.4V because there's no load on the system and it uses the high frequency to quickly get some background tasks done. It's entirely within spec.

[@Chicken-o5e]

@SkatterBencher thank you so much. Curve shaper is such a nice new feature!

[@PuneetGupta724]

Will these settings make it faster than 7800x3d in games? Its a 200 mhz boost 🧐

[@Speak_Out_and_Remove_All_Doubt]

I wonder why AMD and Intel don't use what you do in the first place as in general your settings will work on most samples so even if they scale it back a little to work on pretty much everything it would still be a big improvement over stock.

[@pokcaU]

im happy they dont do so, since its more fun for us and the amd and intel presets will always give a baseline without stability issues :D nevertheless skatterbencher mostly does per core co, meaning its impossible to adopt the same co from one sample to another

The fclk is all cpu dependent amd the lower the soc voltage the higher it goes uclk is also cpu dependent and tops out at 3200 for 90% of cpus and if u are extra lucky 3300. If u are running 6400 fclk shoudl be set to 2133 and uclk should be in 1 to 1 mode
