Any information on the following sample: Intel Xeon 1.30 GHz Sapphire Rapids QWY2 LGA4677 Server ES CPU Processor
CPU image
Picked up a board for $200 and hoping to make use of it:
ASRock Rack SPC741D8-2L2T CEB Server Motherboard Single Socket 4th Gen Intel® Xeon® Scalable Processors (LGA 4677) C741 4 PCIe gen5 Dual 10G & 1G LAN
It seems this board has the least amount of compatibility, saw one comment recommend return this board for gigabyte but for the price is it worth the hassle? This cpu doesn’t have much information but this is in the US so a return will be much easier and cheaper compared to China imports.

stepping B0. return or put in trash bin.
go with QYFS, $115 usd
better compat. than supermicro.
i have QYFQ run on SPC741D8UD-2T_X550 so i should able make a BIOS for SPC741D8-2L2T to run QYFS (or EMR A0 ES)
Hello, I can acquire Asrock W790 WS 2.0 for a good price and wanted to ask about the best ES for this board, are there any significant diferrences between QYFS, QYFR models? I can't really find the QYK8 variant anywhere that ships to me. Is rdimm ecc ram required to run such setup?

HWinfo cannot distinguish them.
sure it is, UDIMM does not fit for good reason
UDIMM +5V supply
RDIMM +12V supply
Thank you for saving me a week or 3 of frustration. I’ll look into both processors.
Is there a reason to choose one or the other from what you listed? More feature complete or hidden features?
I found a listing that includes the QYFS and goes up to QYFR. I don’t mind paying a slightly higher price to guarantee a couple less headaches.
So wondering and checking which of these is “better” since core count and clock speed is close enough for me: QYFQ, QYFP, QYFU, QYFR, QYFS
I’ll do some more digging on the differences through the forum (over 200 pages now) and google around.
i think they write because HWinfo reports "QYFS/QYFR ES2"
QYFQ, QYFP = 270W low clocks
QYFU = single socket only
QYFS(QYFR) = best value
i realy don't know. i don't have a HWinfo report from QYFR to compare with QYFS.
one of them can be ES of processor who was not included in the final SKU list, or a ES of OEM custom.
All of these would require a modded bios right or a specific bios version?
Looked at the motherboard es spreadsheet and it didn’t list any d0 chips for asrock c741 but if you can help with the bios, I’ll order one of these.
It did have some e0 chips listed: Q0KL,Q0KG,Q0KH,Q0KS,Q0KJ
Since these share microcode with production e5 chips I should be able to use any official bios release? Same with QS samples? I could get away with lower core count too but the prices jump quickly.

Found an old reply that QYFR does NOT have accelerators and someone else saying QYFS does have accelerators.
SPR-SP D0 ES work with Gigabyte up to R12/R17 BIOS (varies with model)
CSI/MRC 114.D30 = work
CSI/MRC 115.D14 = not work
mod. BIOS required in any case for SPR D0 and EMR A0 ES, i have D0 and A0 working on ASRock Rack C741.
later SPR-SP E0 stepping work (but not early E0 like Q03J e.g.)
QS is Retail silicon just with ES bit enabled, work on all motherboards who support the Retail version.

Hello,
Need some help badly.
Gigabyte MS73-HB1 not posting with 2 CPU's - Boots fine with each CPU only in socket 0
Mobo is at the latest BIOS (R20) (and new)
Each ES Xeon will boot fine when only in CPU0 socket. Same RAM, GPU, everything. The other CPU swapped in socket 0, also fine, both each boot ok.
However, when both CPU are in it will not post at all. Socket pins are fine this is a new MoBo. Change order of CPU in sockets, swapped RAM, make sure thermal paste / heatsinks / fans are perfect, still nothing.
Reset BIOS, changed to new CMOS battery, still nothing. Any idea what is going on here?

UP processors like 8571N ES ? they don't work in pairs.
ES is not SPR-SP D0 because they don't work with R20 anymore...(stop at "chipset initialize")
some models are mobo for servers with auto bifurcation enabled.
there are many EPYC motherboard without bifurcation.
edit:
Z13PE
D16 or D32 ?
"0000" is normal for ES (non QS)
for EMR stepping A0 ES you need mod. BIOS to support dual processor.
Q2SG is ES of 8581C OEM model.
i am not sure if the MS73 (specs. max. TDP 2x 270W)supports dual 385W TDP.
PM you now with the BIOS.
