check first if all 5 are ok. i bought 2 Hynix RDIMMs from ebay(used) and both are DOA(missing SMT components)

same here, 4/8 missing SMT resistors despite being packaged in their original trays.
Thanks all for your advice. Finally got all the parts to trickle in and did my build last night. QYFS, 256 GB memory and MS03-CE0. Was a bit bummed out at first as I couldn't get a POST (no beeps, no fans, just flashing green lights on the MB). But it turned out to be a really embarrassing problem. I was reading the MB header wrong for the power button and it was not connected properly lol (after trying another power supply, cycling all memory sticks one by one and re-seating CPU).
Memory perf is meh but I'm running at 4800. But I got a good deal on the memory. About $190 USD per 64 GB RDIMM. There is a setting in BIOS to increase the memory frequency but it has no effect.
On thing I'm noticing is that the pre-os POST time is quite long (a few minutes).

you have 4 sticks, one per tile. for optimized latency the mem. is running as single channel (1-way IMC)
you can get better bandwidth with all 8 channels populated.
Thanks. I realize that. Just didn't want to spend all that money before knowing the CPU was good. I may buy more now. They were actually $170 USD/64 GB RDIMM. I also didn't know if the memory would be ok. I bought them on Amazon from a new seller selling them used. But everything went smoothlty and the shipping was quick!
Would GIGABYTE MW83-RP0 work with QYFS? And/or Q0KL (E0) Stepping?
on the official specs they only say W-3400 cpu, there is no diagram for "W-2400" or other scalables. So that would mean no, but, since Gigabyte boards in general seem to have good support for ES i still have some hope

MW83-RP0 BIOS missing microcode for D0, maybe can be added.
stepping E0 no way.
chipset W790 is only for W-3400/W-2400
SPR-WS stepping E0 is supported, but Q0KL is SPR-SP(not xeon W)
ASUS Z13PE-D16 don't support stepping D0 cpuid 806F3
but EMR ES stepping A0 cpuid C06F1 ( means not: supported in any case, Tyan & supermicro report no support for EMR A0 )
EMR QS A1 cpuid C06F2 is same than prod.unit but ES bit set.

Q0KS with X13SEI-F, everything fine but idle power up to 150w? (default BIOS settings, windows high performance power)
LOL, thats not idle.
usual with "windows high performance power"
this keeps the cores at baseclock, mesh/cache/uncore in high clock state, no energy savings.
"windows high performance power" is not required.
then wait for all cores down to 800mhz and check again.
and try this
"out of bands" mode instead of "native" for the "hardware p-states" setting in the BIOS
( if your FAN control is by Core temp the EMIBs can overheating, do only with Water.)

P-State / Power Plan causes massive lagg on Windows (Sapphire Rapids)
Hi there, I just upgraded my system from a X299 platform to W790 and a Intel Xeon w5-3435X core and immediately noticed a massive UI lagg/stuttering when moving windows or trying to select something in the Windows explorer. This only happens when the CPU is idling and the frequency got lowered. A...

Solved the issue of system response slow, but the power returned to 150w
Got a BSOD (memory management) when opening hwinfo, this classic issue hasn't been fixed yet
its HWinfo issue not only on sapphire rapids.Got a BSOD (memory management) when opening hwinfo, this classic issue hasn't been fixed yet
settings: safety, check: "safe scan of potentialy problematic PCI devies"

have tried it and there has been no change
Mesh frequency is crucial
Emib has made the legacy c-state issues on icx more prominent
if you have prod.unit you can ask supermicro and intel for help.
and windows like to threadhopping doesn't help with this, every new core must be waked up and...crap.
btw: intel lower the EMIB count from 10 to 3 on EMR.
I also noticed such high idle power or lag issues with QYFS on Asus W790 ACE on windows depending on the profile MB. Since I mainly work under linux it was not very urgent, but i was planning to look in to this new windows 11 pro for Workstations version. There are keys for about 20 Euro online available. And maybe they fix some of the setting that are not favorable for these cpu's. Another idea which came to late to try for me is to use quick cpu software. I use it for my laptop. But i wanted to try it on the workstation there its possible to change settings about core parking, and many other settings not easily accessible from windows itself. I returned my MB so cant try anything now.

I downloaded it and trying, but I'm not sure how to use it yet
I guess windows software cannot solve this issue, and Intel has not fixed it from D0 to E0,but I saw lower idle power in E3 8461V
Tested,no improved in official Windows 11
150w is not unacceptable, E0 is good,CPU is use for running not sleeping
