Seller offered it ($200) so figured I could test it out, worst case I'll swap it to one of the gigabyte servers. I assume there will be some trial and error to get any HP working. Thanks for helping me tho.

Does anyone have any experience with the Tyan S5652 and the Sapphire Rapids ES/QS parts? Would a D0 stepping part work in that board?

Thanks, good to know. It's a big thread, I did see that supermicro is no good for ES parts, but I guess I missed the comments on Tyan.

What about the ASRock Rack SPC741D8-2L2T or GIGABYTE MS03-CE0? I'm trying to find something relatively economical that has lots of usable PCIe x16 slots, and I don't really need more than one CPU. MS33-AR0 is not very interesting because half the slots are blocked by the RAM. MS73-HB1 I guess might be a decent option, but I don't really need two CPUs and with only one CPU installed presumably some of the PCIe slots will not be usable. I suppose ASRock Rack SPC741D16X-2T might also be an option worth considering, similar setup as the MS73-HB1.

ASRock C741 series supports ONLY E-Stepping ES/QS/PRD processors, same than supermicro/Tyan.
(maybe the BIOS of ASRockRack/Tyan can be modded,)
Currently ALL Gigabyte C741 boards support D0 stepping SPR-SP ES. if you update BIOS, don't update Intel ME.

Got it. Are there any options other than gigabyte that are worth considering? Or is that the only option at the moment that doesn't involve modding the BIOS?

Also, is there a summary/compilation of this sort of information somewhere?

8470 ES Q0KL stepping E0 2.1Ghz 52cores.
runs on gigabyte,supermicro and asus. asrock rack not tested.

Hello everyone, I just bought an ASRock EPC621D8A from ebay. I also bought a 8251 QS (QPLC). I put it in my motherboard and plug in my psu and the leds turn on but the computer will not start when I press the power button. Did I mess up and pick the wrong CPU? I also bought two more: QPKD and QMQ9. If it is my CPU that is faulty or incompatible, do you think those two QS CPUs would be fine? Thanks in advance

all of them should work. processor not properly installed or other things wrong (bad mobo/cpu/psu)
Hello, thank you for your response. I just tried a different cpu that came in today (the QS QPKD) and my computer is not booting when I short the power switch pins. Do you think it's possible that it will not start due to an outdated BIOS? Here is a pic of my setup. When the PSU is turned on, two green LEDS are on.

Where is the cpu cooler? I assume you are not trying to turn on your system with CPU just laying in the socket, right? Right?…

Right sorry, I took that off. The cooler is an AlphaCool Eisbaer Aurora Pro 240mm, but even without it installed I won't get anywhere... even the PSU fan will not start when trying to power on

the LEDs are power led and BMC ASPEED heartbeat led. should start blinking after some seconds.
If the FAN is not turn on the CPU gets no power and no x86 code is executed, so can not BIOS.
BIOS ver. is printed on the sticker of the socketed BIOS chip.
i see you use not the CPU carrier/frame, maybe bent some socket pins now ?
installation of CPU needs the screws 3&4 turned to the end to lift up the leaf-springs topmost.

BIOS ver. seems valid and cpu socket pins seem okay, pictures: I will buy the cpu frame since the mobo did not come with it when i bought it
EDIT: By the way do you have any recommendations for where to buy the cpu carrier?
EDIT2: I ended up buying this one: SuperMicro BKT-0126L CPU Processer Package Carrier 10122321 | eBay

The question RolloZ170 is asking - does it have a life (right led signal) in BMC if you power it without CPU?
Then next debugging step - can you connect to BMC? (still without CPU installed).
Only after all above are fine - we can start CPU install/debug stage
(including checking boot codes even if there are CPU, RAM or peripheral related issues)

So I also got one of kizune's E3 8461Vs off ebay, but try as I might, it doesnt seem to have AMX enabled.
HWINFO64 doesn't show AMX (See screenshot), /proc/cpuinfo doesnt show it under flags either:
Code:

Trying to compile Intel's AMX demo (GitHub - intel/AMX-TMUL-Code-Samples: Code samples related to Intel(R) AMX) with their default -march=native on gcc-12 doesnt work, claiming that the platform doesnt support it. Overriding it with -march=sapphirerapids does get it to compile, but it crashes upon trying to run the build program.

Any tips for getting AMX enabled? I have it in an X13SEM-F since its supposed to be for a portable system. I tried updating the bios from 1.1 (what it shipped with) to 1.4, which did fix a number of significant bugs with the platform including an inability to turn off, but did not fix the missing AMX instructions. I see that sam55todd previously got AMX working though, also on a supermicro board and using one of the same E3 8461Vs from Kizune, a few pages back.

Also here is the version of microcode running in bios 1.4 for that board:

Hmm. Just got the fresh CPU out of the box, the motherboard is Supermicro X13SEI-F, BIOS 1.4 (latest) factory default settings.
Windows 11 Pro, again - no special settings or drivers installed, fresh copy with the standard chipset drivers downloaded from Supermicro.
That all is very concerning. I would try to reset BIOS settings to the factory default and make sure you installed the chipset driver from Supermicro support page for the motherboard. If you think that the problem is with the CPU - ping me, i will replace it with the one that i just tested.
