Yes, I gave up all attempts and returned X12SPL, but the CPU is very difficult to handle,it's can't return. The problem is not with the supermicro because it can run PRD CPU very well, but with the es CPU. Should never try ICX Step5

No x12spi-n6 found only x12dpi-n6 and x12spi-tf. Tried mu72-su0, the hwinfo/cpuz bug still exists and there is a problem of a single core being continuously full (supermicro does not have this problem)，I don't plan to continue trying to use this CPU full of bug
Thank you for your replies, they are very helpful
had BSOD with SPR PRD unit. should be solved in latest Hwinfo package.
running both same time results usualy in problems, both of them use direct hw access.
This looks a little suspect, but has anyone seen and/or know anything about these 3945x QS cpus?
Intel Xeon W9-3495X QS CPU processor 56 core 112 threads 1.9GHZ LGA4677 350W
Intel Xeon W9-3495X QS CPU processor 56 core 112 threads 1.9GHZ LGA4677 350W
QS = no intel support, no intel warranty.
QS same specs than production unit. with same stepping.
Thanks Rollo! Haven’t used this seller before - might take the leap, if I do I’ll report back. Although QYFQ cpus for cheap seem like a more interesting idea
It would require a different chipset/MB, plus D0 stepping materially limits choices of brands.
QYFP,QYFQ D0 is working fine on ASUS WS W790 Ace(BIOS 0403) and ASUS Pro WS W790E-Sage SE(BIOS 0215)

Hi RolloZ170, I registered an account here just so I could ask you a question HAHAHA.. I see that QYFQ D0 is working on Asus W790E Sage, is this also the case for QYFU? And is QYFU superior to QYFQ since it can run at higher clockspeeds?
i see no reason why QYFU should not working.
i have WS W790 Ace and QYFQ,QYFP,QY0C and QY06 runs fine with BIOS 0403
(still issues with BIOS 0506/0705 win10/11 - circle dots freeze, except with QYF )
BIOS tweak solved that issue.
yes but note QYFU is single socket only(in case you want to sell it in the future)
QYFU base 1.8Ghz turbo 3.5 Ghz, all core nonAVX 2,9 Ghz , 300W
QYFQbase 1.5Ghz turbo 3.3 Ghz, all core nonAVX 2,5 Ghz , 270W

There are still L0/C0 step-microcode displays (tables) in the newly released bios relNote PDF files for md72 and mu72, but do they no longer support these CPUs?
even these MCUs are still available in the supermicro BIOSs. but nor work,
imho intel ME/CSE/SPS is blocking before any x86 code is executed.
on gigabyte you may able to update BIOS but not ME/SPS.
Thank you for the response, really appreciate the info! Just a couple more questions, do you happen to know if the supermicro X13SWA-TF motherboard can run these CPUs too?
And I'd imagine if the Asus W790 Ace can take QYFQ,QYFP,QY0C and QY06, then something like QYFR and QYFX should also theoretically run, right?

check with BIOS 3.0a (or b)
on a X11SPA the 8273CL works only with 3.0b, later BIOS stop at code 79.
yes, but not tested.
NO, supermicro removed PRD stepping microcode D0 cpuid806f3 (same Tyan and ASRockRack)
if you want to run non PRD stepping ES, stay away from supermicro C741.
X13SRA / X13SWA runs not Root of Trust(RoT) firmware, you can add the microcode, but I'm afraid it still doesn't work then.
update: got D0/E0 working on X13SRA with old ME.

Thank you for the reply! You have been extremely helpful. I’ll report back here once I finalise my build and get it running
You are right, they didm't work.
Also, although they work with Gb MD72-HBX, that MB got some issue with pcie slot (3 slots not work with pcie riser, need retimer card)
I'm currenly plan to moving to ES2 CPU (qwaq,qwas), I'm woundering if these work fine with SM X12DAI or X12DPG with 1.4b bios?
Thanks in advance.
Got this from X12DAI 1.5 BIOS:
