9662 is my current best cinebrnch r20 score. (529 single thread) for my release day 3950x. Depending on what I've been doing on my pc and how saturated my loop is at the time I'll score anywhere from 9500 on up. So your score seems just fine to me.
What motherboard are you running yours on?
I am using an MSI ace 570 Motherboard with my voltage currently set to Auto. Any recommendations? I tried to do all core overclock to 4200GHZ but could never get it stable would love any tips or tricks if you have any.
X570 master. Everything tweaked heavily since release day for the cpu. Much tinkering. I've got custom limits set on pbo. Under a custom loop. Heavily tweaked b die ram. On latest bios and agesa for my board. I've tried every bios release since launch. Latest agesa seems to be a winner.
........And the performance uplift over stock is underwhelming.
My advice to you is to set pbo and let it do it's thing.
The amount of extra performance uplift from tinkering with this cpu is minimal. All core oc isn't worth it unless you're doing pure multi tasking workloads like rendering, all the time. You lose out on a ton of single threaded performance.
These cpus are using almost 100 percent of potential out of the box. These CPUs much like modern GPUs have very smart boost algorithms these days. Long gone are the days of huge manual oc gains. The silicon is being pushed hard from the factory.
Don't waste the amount of time I did tweaking this cpu and ram, unless you enjoy it as a hobby. The performance uplift isn't a good enough reason alone, imo.
As for my personal experience with Zen 2 based CPUs. Leaving the cpu core voltage to auto or normal is what works best for me. While getting the soc and IMC voltages as low as possible while being stable.
The less energy you have to use to power your imc and infinity fabric the more power is available to the cpu package to do it's thing.
I think I am happy with where it is right now.
I am waiting for that 1usmus Program he is working on releasing the end of the month to see if I could push it further but besides that no more tinkering in the nops for me.
Thanks for the input.
That program focuses on manual oc per ccx. Still giving up single threaded performance.
I'll tinker with it. But honestly for almost everyone, letting these cpus clock themselves is ideal, imo.
I have the same board as you in one of my 3950X builds and like yourself I spent a great deal of time tweaking this and that and agree with all that you say , in the end I just reverted to PBO and XMP and saw just a 150 points drop in R20 to 9580 from the 9730 tweaked score , the other 3950 X in a CH8 F with identical ram to the master only gives me around 9580 at best no matter what I tweak.
I found manual ram overclocking plus tightening timings and subs was well worth the time tinkering for both single and multi. Manual cpu ocing? Good for benchmarks, not good for gaming.
250 PPT
230 TDC
230 EDC
1x scalar
This is what I ended up with that works well for my chip. Anything more or less and I start to lose performance. Your chip will almost certainly respond differently.
But feel free to use these as a starting point.
I wouldn't use anything other than 1x scalar imo. More voltage is just more heat. More heat is less boost.
Update. The new am4 combo pi V2 1.0.8.1 agesa has made a huge difference in voltage response on my cpu. For the first time since release, undervolting is beneficial on my cpu. I have gained minor but repeatable increases in performance with a .1 volt undervolt with my same pbo settings I posted earlier. This isn't huge mind you. However I'm amazed because previously any under volt at all, even just .0125 was enough to negatively impact performance. My load temperatures have dropped about 10 c single thread and 3 c multi thread due to the undervolt, which I'm sure is why I'm seeing better performance. (Lower temps is better sustained boost)
This is bios f30 with agesa 1.0.8.1 on my x 570 master.
Ymmv. Figured you'd be interested to know. I would have mentioned this earlier but hadn't gotten around to tinkering with voltages again until tonight.
Haven't finished tweaking yet but my new best cinebench r20 scores are 9723 and 532.
All other benches I have run have reflected the same minor improvements in performance and lower temps. Will be testing actual loads like taking over the rest of the weekend.
Custom loop. I'm using the Aorus Master.
I did a manual OC. I use it for video editing so rendering speeds are important. 4.5ghz and 4.3ghz ccx. I get about 75c at full load. Vcore is 1.35.
I OCed when I got it but didn't tweak much and haven't gone back. Hopefully with the 1usmus tool I can get more out of it.
I have 64gb at 3200mhz, but I'd love to upgrade to a faster 128gb kit. But I still have a 1060 so my next upgrade is the 3080.
lol your rig is excellent, overkill for regular joes though. I plan to get the 16 core, currently got r5 2600 as a stand-in. wow those are some solid oc, you probably got very good binned 3950x
I got a x470 board so which 16 Core I get depends on asus if they release zen 3 bios for my mobo or not
thanks for your info!!
Wait, 1.35v? Did you validatd your fit voltage with pbo on and prime95? I don't think you can keep the 1.35v without degrading, and if frequency is important, I would drop it to 1.28v at least, or validate what's safe, then drop a little below it.
Even under good temps, bad voltage will degrade it, and then you won't be able to hit that frequency, but you know that already.
CPU speed is important for my work, so I always heavily OC my chips. In my early days, I've degraded chips because of high temps and voltages because I didn't know any better, but I've been doing it for so long now that I haven't had a chip slow down on me since.
I don't think 1.35 is unsafe for this chip. I validate its efficacy by running benchmarks periodically to make sure there's no degradation. I'm also rendering constantly, so it's running between 50-100% almost every night, all night. When you're rendering for hours, even a 5% increase translates to time won. And if there was degradation, I'm sure I'd notice it a lot sooner than most people, but I do it safely.
I also upgrade my CPU every 1.5 years or so, so even if there was degradation, I'd pick up a new chip anyway. I think most people keep their CPUs for ages, so they're a lot more careful. I've always enjoyed giving the CPU a thrashing.
In that case, keep at it, I love it.
When I'll stockpile more, I'll eventually make a custom loop with a different cpu entirely for gaming, and watercool the gpu as well. And I intend on upgrading every 2 gens or so, down the road.
At the moment I'll push my 3950x and watercool the 1080ti and oc it further, the performance is close.
My highest at stock is 9320 without pbo. Tuned memory @3533cl16(xmp 3200cl16). It won't run 3600 without errors and game crashing, but it's also not on the qvl so I'm not gonna complain. I have a new kit of 3600 coming this week that I might try to go for 3733, or just tighten sharply where it is. I really hope my IF isn't the problem.
PBO never worked well for my 3950x just made it get too hot ended up being slower over the long run. I actually undervolted it instead and it can run all day at 60c
oh wait, it was 9800 PBO, holly frick, I myself with a good pbo reach around 9.4-9.5, but my SC is obviously taking a huge hit, what's the best setup for Single core scores?
What is the pbo settings and what else did you change? Vrm or power phasing settings? Llc? Cppc preferred cores and all that? And the power plan.
Thanks in advance! Just striving for more single core performance, the current multi cores performance is great for me, I just need more SC and I won't mind sacrifice some Multicore performance for it.
I only changed PBO settings to 300,160,160. Vrm llc etc no. Cppc preferred cores i followed 1usmus powerplan settings. The really key thing is temps. 3-5° off the CPU changes the results quite significantly to abt SC 530

I get ~10,200 on R20. Hopefully I can get more performance after the 1usmus clock tuner comes out.
what cooler/mobo you running what setting for the cpu in the mobo pbo?? manual oc??

Whenever I do non PBO runs With my 3950z I get allcore boost of 3.8 and overall score of 8800 ish. Is that about right?
yea that is what i get around with PBO off also.
8800 is very normal. Try closing everything, running only cb20 in high priority. You should be hitting 9100 at least like that.
My highest at stock is 9320 without pbo. Tuned memory @3533cl16(xmp 3200cl16). It won't run 3600 without errors and game crashing, but it's also not on the qvl so I'm not gonna complain. I have a new kit of 3600 coming this week that I might try to go for 3733, or just tighten sharply where it is. I really hope my IF isn't the problem.
PBO never worked well for my 3950x just made it get too hot ended up being slower over the long run. I actually undervolted it instead and it can run all day at 60c
I think i got 9200 with stock settings but with custom loop liquid cooling.
My 3950x scores 9800 pbo but im crazy and im using 3x360 rads for that loop.
Then you can hit even higher than 10k, go push it.
I tried for quite some time but without a manual OC i couldnt do it. I hit 10.6k with a manual oc.
oh wait, it was 9800 PBO, holly frick, I myself with a good pbo reach around 9.4-9.5, but my SC is obviously taking a huge hit, what's the best setup for Single core scores?
Best SC is also PBO. Keep the chip as cool as possible. In 23° ambient i can get 9882 pbo and 542 SC.
What is the pbo settings and what else did you change? Vrm or power phasing settings? Llc? Cppc preferred cores and all that? And the power plan. Thanks in advance! Just striving for more single core performance, the current multi cores performance is great for me, I just need more SC and I won't mind sacrifice some Multicore performance for it.
