QS = no intel support, no intel warranty.
QS same specs than production unit. with same stepping.

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?

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:

For anyone who is still interested in Xeon 8273CL - here is my full analysis on the CPU.
Basically:
- It can't work in 4-way / 8-way due to being locked down to 2-way physically inside the CPU
- It needs a special version of microcode, and once that presents, any Supermicro X11 motherboard should be able to use it (M/B still must support 165W TDP)

Ok, i finally got myself an Asus Pro WS W790-ACE and tried all my available processors on it. Bottom line: the E3 stepping processors do not work with any of the available BIOS. Tested processors:
Q16Z Xeon Platinum 8461V stepping E3 - stops at code 00
Q0MN Xeon Platinum 8468 stepping E3 - stops at code 00
QY36 Xeon Platinum 8480+ stepping C2 - stops at code 04
Looks like only D stepping processors working with this motherboard. Will have to return Asus - which is quite sad, the deal was good and the motherboard is in an new open box condition. And i really like the layout and features. Such a bummer
Not sure i want to spend money buying D0 version of processor - will probably just stick with the tested and tried Supermicro board for now.

i got some more POST codes with injected C-stepping microccode in the BIOS. the ref.codes may too actual to init.the old stepping thought.
normaly not the task of ME. and same cpuid and microcode.
i noticed the D-Stepping run with DMI4x8 on my W790 Ace. maybe E steppings SPR-SP can't.
btw: D0 cpuid806f3 is PRD stepping
