all listing at ebay say Q2JH but show Q2SR 1.7Ghz.
2.0 Ghz is not that improvement, in IDLE processors should park cores (EIST) and under load at all core turbo clock.
if you buy it over ebay there is no risk.

There are no longer listings on the UK eBay site for individual EMR ES CPUs, so I tried directly messaging the sellers who were offering them bundled with a motherboard in case they could do something. One said they didn't have any left and one said they had Q2JH available. I could use the US site I guess.
Surely the different base clock numbers must mean something, or they wouldn't quote a base clock. But I'm concerned with whether there are important differences other than that, if these are known about at all.
Q2JH is new to me but price wise not attractive.
Q2JH should be cheaper to compete with Q2SR/Q2SP.
but ebay prices are doubled comparted to goofish/taobao.
There were rumours that late chips were basically PVT stage - they might have different amount of accelerators (QAT, DLB and other stuff), different turbo config and so on. But difference shouldn't be that much.
all have fun to blaim intel for they're alleged 12 steppings to build sapphire rapids which is not true.
( you have to separate the physical chops(MCC,XCC) and SPR-HBM )
start 806F0(A0), final 806F3 (D0) here intel decided to rebuild silicon, shrink die sizes. E0,E2,E3,E5
now we have Emerald Rapids:
?? cpuid C06F0 << anyone seen ES with that stepping ???
A0 cpuid C06F1
A1 cpuid C06F2 final
Hi everyone. I have a Gigabyte MS73-HB1 motherboard and 2x Intel Xeon Platinum 8480 (ES QYFS) processors. Did I understand correctly that this combination works on all BIOS versions without modifications? I want to purchase Samsung rdmimm PC5 64GB RAM. Will it work with my motherboard? If I were to acquire 2x Intel Xeon Platinum 8592 (ES Q2SR), would they work with the motherboard and what potential issues might arise?
yes (so far)
yes.
EMR-SP A0 (Q2SR) need modified BIOS, PM me if you have EMR ES at home.
do not buy very very old Samsung DDR5 RDIMM, ask before because there is an issue with early DRAM chips.
Hi,
I have an AsRock Rack SPC621D8U-2T motherboard and a QWAT CPU, but the system won't boot (there is no video output, and the BMC cannot detect any CPU or memory). This is the Firmware Information shown in the BMC:
- BMC Firmware Version: 0.02.01
- BIOS Firmware Version: L1.01J
- SPS Firmware Version: 4.4.4.202
- Microcode Version: 0d00037b
Thank you!
knwon working motherboard and CPU ?
what should happen other than it works ? you can update if not work and do further throubleshooting.
this is done by BIOS POST, no POST = no data
Thank you for your reply! I purchased the motherboard and CPU from different sellers, and both of them are tested and confirmed they were working.
I downloaded BIOS version 1.00 for the SPC621D8U-2T motherboard, which is the initial release. I used the MCExtractor tool (GitHub - platomav/MCExtractor: Intel, AMD, VIA & Freescale Microcode Extraction Tool) to analyze the 1.00 BIOS, and it shows the SPS version is 4.4.4.53.
I then tried downgrading the BIOS to version 1.00 via the BMC, and the BMC reported that the BIOS was flashed successfully. After that, I unplugged the power and waited for 30 seconds before plugging it back in. Unfortunately, the SPS version still shows as 4.4.4.202, and the system won't boot. Does this mean there is some mechanism preventing SPS from being downgraded? Are there any other methods I could try? Thanks again!
ok. if you got a real QWAT (it is printed on it right?) it should work.
even if i say "if you want to run ES avoid Supermicro" QWAT runs on Supermicro.
1) does the FAN spins after you press the power btn ?
2) do you use standard Cooler and Torque-screwdriver ? (0.9Nm click) or turn the four T30 crosswise(only 360 degree each stroke) until they not turn ?
3) remove CPU and check socket pins. provide a Picture ?
I agree, I have actually tested and found that Qwat and qwas can run perfectly on the Supermicro X12 motherboard.
Yes, it's a real one with QWAT printed on it, and the fan spins after I press the power btn. But - I installed the CPU using a regular T30 screwdriver without torque control, which may have been a big mistake. I've now purchased the proper tool, and I hope reinstalling the CPU will solve the issue. I'll follow up later, thank you for your kind help!
you need a torque-screwdriver once, after that i guessyoue feel how much you can turn&where is the end.
some are not brave enough and the CPU is not properly pressed into the socket, same at LGA4677/4710/7529 socket.
I got my first torque-screwdriver only when I got SP5 system. It took me 3-4 attempts to get the feeling right for LGA4677, but it is basically, as I think you said to me once, just "finger tight" - basically tighten it until the force required starts to grow fast, and that is about the correct torque.
searched and found. i remember i had a SPC621D8-2L2T(sold)
QU9B (B0/L0 ES1) runs still with BIOS P1.20
but i have the QU9B and QVM7 at home.
I reinstalled the CPU using a torque screwdriver, and the system booted successfully! The issue was indeed caused by improper installation. In addition, I re-flashed the official BIOS for the SPC621D8U-2T motherboard (version P1.20), and the system still booted correctly, confirming that the QWAT CPU is still supported.
Thank you again for your help!
