Xeon Max HBM models do not have E steppings but A/B
stepping U0 is SPR-EE
Q22Q 806F5 platform 10 should be stepping B1.
Could you please send me the oldest BIOS for the Gigabyte MS03-CE0? I'd like to check what it contains. Also, I'm curious - Can I add microcode by myself to run these CPUs on Gig's motherboard?

This is cpu-z screenshot of qygg, run on early supermicro's motherboard.
Someone bought a OEM test board and tried to use this cpu. Without 806f1 microcode, system don't post. After inserting this microcode, system can display something but stuck at self check.
I have the backup files of the BIOS for these super early versions of the Supermicro motherboards. If you need their microcode, please message me and I will send the files to you.

Here are their screenshots. They even date back to 2021.

first is F01 but i don't have. i have F09 and there is the RelNotes from.

if it would that easy those cpu's will run on every motherboard except supermicro(RoT BIOS can't be modified)
you need old Intel RC/MRC coded BIOS.

i have it all and tried all. i have BIOS for supermicro x13sei but you can't flash it on RoT enabled boards.

Yes, because their CPLDs are different. I have tested it on the Supermicro X13SEW. However, placing the new version of the CPLD, BMC, and BIOS on the version 1.0 motherboard does not work properly. I suspect that Supermicro has made some changes to the hardware.

and debug motherboard have Debug cert enabled and accept only BIOS with that signature.
STDsp.bin = sp = Standard BIOS, signed production
STDsd.bin = Standard BIOS, signed debug
TESsd.bin = TEST BIOS, signed debug
CPLD FW needs to changed often, e.g. to run SPR HBM only (no RAM)

Merry Christmas, everyone. I've been feeling quite frustrated lately because I mistakenly bought a CPU that won't boot. I had faith in my motherboard, which has the 806f1 microcode (the C741 southbridge is also an es(qykv) from China, with a es early BIOS), as it can directly boot D0 stepping CPUs. But despite trying every method, I still can't get this Xeon Max A0 ES to boot. Perhaps I need some technical support. If I could get it to work, it would make a fantastic toy—112 cores and 128GB of HBM2 are quite impressive (even though it likely has many bugs).I am machine-translated, so please ignore my awkward language.

does this motherboard support SPR HBM at all ? HBM needs an additional voltage to the socket some mobo not have,
and the CPLD FW needs to be prepared for HBM models.

The motherboard capable of using the Xeon Max ES with a0 stepping (PCH QX30) remains the only one available even after three years. Upon examining the microcode between them, no differences were found. As for the RC version, it's challenging to locate earlier ones (attempting to use a BIOS from 2021 provided by others also proved unsuccessful). Is there still hope to continue tinkering to get this 9480max up and running? my motherboard pch is qykv(c741 es)

You might be right. Though my socket does support HBM, the CPLD might be preventing it from working. Since the BMC on this motherboard is broken, extracting the firmware is very difficult. It might be time to consider returning it.

What is the letter on the top of cpu?

Thanks for your reply. It's not only problem from microcode. If other parts of bios like SPS doesn't support correspond CPU it still won't work. May I ask what model of motherboard you saved these bios from? Same model (maybe test version only) with your bios
should work.

no, QYGG runs on normal X13/C741 but need early Test/Debug BIOS.
If I get this d bios is it possible to flash into normal version of ms03-ce0??

unknown, possibly it is rejected by BMC flash function. then you need SPI programmer.


we have flashed BIOS T01 on a MS73-HB1, so this should work.
it is possible to enable the hidden options in the BIOS of the ms03-ce0 motherboard, such as enabling the base frequency options
