Keith Myers I never could get any kind of decent all-core turbo speed out of my 2920X with Auto or PBO settings. Just runs way too much voltage for no gains in performance and a ton more heat because of the elevated voltages. I get much better results manually setting an all-core OC with a fixed voltage or a simple offset at much less voltage and a lot less heat.

Roy360 Never realized PBO would draw so much voltage.... (1.46V for a average turbo of 4.15GHz)
Should I manually tweak the voltage? CPU is at 60C during stress tests

I also want to raise the max turbo speed. Is there a way to keep PBO enabled while raising the turbo speed?

Looking at AMD's website it looks like the Max Boost Clock is supposed to be 4.3GHz.
I wonder why my CPU stopped at 4.15GHz even though I max'd out EDC, TDP, and PPT.

cdawall Putsing around with some good memory today. I am curious if I can get a 4 dimm load fully stable at this speed, but these Bdie sure make a world of difference.

Well I have not beaten this poor board up that bad yet, but I am sure my 24/7 clock is not doing it any favors. This runs cooler and at lower voltage over letting PBO do it's thing.

ugotd8 Hi all. This is some data from the https://opendata.blender.org/ site which is compiling blender benchmark statistics when uploaded. They have a 'top50 cpu' list and some other data but they also have 'raw data' available for download. It's a JSON file with every entry ever submitted. I wrote some python code to pull out information on the recent AMD HEDT and high core count mainstream procs from the raw data to help me decide which processor to upgrade to. (footnote: I know the 2990WX did better in linux but I don't run linux so this list is purely windows results)

Blender Opendata 'QUICK' benchmark data for recent AMD processors on Windows

AMD Ryzen Threadripper 3970X (4 entries): fastest: 253 average: 261 (55.15% speedup)
AMD Ryzen Threadripper 3960X (8 entries): fastest: 310 average: 349 (40.03% speedup)
AMD Ryzen Threadripper 2990WX (63 entries): fastest: 296 average: 373 (35.78% speedup)
AMD Ryzen Threadripper 2970WX (18 entries): fastest: 383 average: 471 (18.93% speedup)
AMD Ryzen 9 3950X (23 entries): fastest: 444 average: 488 (16.04% speedup)
AMD Ryzen Threadripper 2950X (50 entries): fastest: 573 average: 636 (-9.39% slower)
AMD Ryzen 9 3900X (295 entries): fastest: 593 average: 665 (-14.53% slower)
AMD Ryzen Threadripper 1950X (102 entries): fastest: 538 average: 673 (-15.74% slower)

The speedup percentage above is relative to my 'old' 1950X overclocked to 3.9Ghz all core which scored 584 on this test. The math is done against the average,not the fastest for each CPU. All scores in seconds, lower is obviously faster.

Blender Opendata 'COMPLETE' benchmark data for recent AMD processors on Windows

AMD Ryzen Threadripper 3970X (1 entries): fastest: 959 average: 959 (55.35% speedup)
AMD Ryzen Threadripper 3960X (2 entries): fastest: 1207 average: 1219 (43.23% speedup)
AMD Ryzen Threadripper 2990WX (19 entries): fastest: 1260 average: 1449 (32.51% speedup)
AMD Ryzen Threadripper 2970WX (6 entries): fastest: 1580 average: 1757 (18.17% speedup)
AMD Ryzen 9 3950X (6 entries): fastest: 1620 average: 1761 (18.02% speedup)
AMD Ryzen Threadripper 2950X (12 entries): fastest: 2154 average: 2304 (-7.28% slower)
AMD Ryzen 9 3900X (71 entries): fastest: 2135 average: 2382 (-10.91% slower)
AMD Ryzen Threadripper 1950X (27 entries): fastest: 1979 average: 2443 (-13.76% slower)

The speedup percentage above is relative to my 'old' 1950X overclocked to 3.9Ghz all core which scored 2148 on this test. The math is done against the average, not the fastest for each CPU. All scores in seconds, lower is obviously faster.

I think the most interesting thing from this data is how the 3950X is virtually tied with the 2970WX of last gen.

Granted these are small sample sizes, the 3000 procs haven't been out that long and not everyone is submitting complete runs to blender opendata site.

Hope some find this information useful, it's not the whole picture but how these do in Blender is at the top of my list.

The BIOS updates have brought my CPU voltage way down however so it somewhat balances out in the long run. Without a doubt I cannot recommend anything with the standard 60A and 8 phase design for overclocking a 2990WX. AVX load and 4.1ghz easily overloads the VRM section. Without at minimum active cooling the VRM section cooler becomes too hot to touch. On an interesting note you can actually hear the VRM section go into low power mode when it flips between 4.1ghz and 55x mhz as safeties built into the motherboard hit. With the VRM section temperature dropped with cold air coming across it (40F actively cooled) I can get the chip a lot higher clock wise with the current BIOS. A proper VRM section could have the better binned chips to at least 4.3 all cores.

With some very heavy CPU tweaking this is what I found to be the max 24/7 stable setting I could pull of assuming I could keep the VRM section cool. Very good performing combo when combined with b-die. There is a lot more ability left in this ram I have not had a chance to even push it yet. I could easily have another 300-500 points locked away in that.



I do hope to see a TRX40 MATX board to replace my current setup when the time comes, but am not holding my breath.

You have to follow your motherboards support instructions. You may have to install your bios update in steps.

J7SC ...Silicone lottery is always omnipresent...but really, I probably learned more with the slouchy pig oc chips (my old nemesis >> 5960x comes to mind) than the smooth operators, like the current 2950x. Also, you're right about the 'weird' RAM multipliers w/ TR2...3400 ok, 3466 ok, 3600ok, but 3533 not ok at any setting whatsoever ...of course, it could be all in the bios...
