Humm maybe I'll try to figure out how to purchase from goofish and look for a Q2SR and then resell the QYK8 since it's too late to go back on that purchase.

I kinda think that stability without the tweak is even more of a problem than POST time. I think I've mentioned before that in that case if it boots, system is basically barely stable.
In addition to all of that, if you get one with accelerators you have better chance using them without stability problems.
Sorry what do you mean with the first part?
Also I may have to do more research but with accelerators?
I've tried using my Q2SR with just stock BIOS on Gigabyte motherboard and found out by trying that unless you have a special BIOS made by RolloZ170 even after it boots, OS will be unstable. That is not an issue with Rollo's BIOS.
Up to you. TLDR - Xeon Sapphire Rapids and Emerald Rapids might have some extra accelerators built in in some quantity.
DSA - I think that one is always available in some extent. There is a part that always should work - if a PCIe device supports that, data can bypass RAM and be available directly in L3 cache (I personally use that for my experiments with Networking). In SPR/EMR that got improved and you now can theoretically do custom pre-post processing of that data on that accelerator directly.
QAT - that might not be available. HW Encryption/compression accelerator.
IAA - in-memory analytics accelerator. Some sort of pre-processing that databases can use, and there are some opensource ones that uses it.
DLB - Dynamic Load Balancer. Hardware queues that software can use to direct PCIe communcation to one or another. At least that is how I understand it, never used it.
See 5th Gen Intel® Xeon® Scalable Processors – Intel® on Demand...
And basically with all Engineering Sample CPUs - there is always a chance that something is broken and was fixed before QS or Production CPUs. For Sapphire Rapids final stepping is E5, and ES are D0 or E0, they have more chances on something being broken and probably terribly broken. Also as far as I remember, accelerators were not changed in EMR and therefore chances for them to work on EMR ES are higher. Same goes for AMX btw, as that was a new feature in SPR.
So if your workloads uses any of that (or you want to play with that) - there is a chance that EMR A0 would be more usable/stable. Just CPU cores though seems to be stable enough for me on both SPR E0 and EMR A0 (my network tests required quiet a lot of data processing that involved AVX2 and AVX512). Basically keep in mind that ES are not production units and there is always non-0 chance that something won't work. And there are more chances that something new, that was changed or introduced in that generation, would be broken.
Would anyone happen to have a link to a Q3W7 8592+ on Taobao or Goofish? I couldn't find one using the Taobao android app. I did find one on Goofish using the Android app, but the app has been updated to require an account to get the link. I'm in the US so anytime I create an account it's automatically flagged for verification before I can do anything with it. I was hoping to use Super Buy to get the processor shipped over to me.
Do you know where the instructions for patching or downloading that special bios are? I was looking through his post history and wasn't sure which BIOS you were referring to. I was thinking about trying this on a Gigabyte MS33-AR0 with a Q3W7
if you mean this, it is a defective CPU.

Q3W7 is QS stepping A1 not patch required.
stepping A0 was working until blocked by BIOS update.
Oh OK, I wasn't sure what the stepping cutoff for emerald rapids was on Gigabyte boards. I saw that it said it was defective, but I thought it might have meant in terms of it being an engineering sample vs a production processor. Do Q3w7 come up often on Taobao or Goofish? I saw another user saying they had bought one for 130 EUR so it sounded interesting.if you mean this, it is a defective CPU.

there is currently no consumer motherboard with EMR A0 support(means with uptodate/actual BIOS)
sure, as 8592+ "display" mostly means QS
(ES2 A0 shows "0000" = no display)
and he reported he got it and the CPU is working ?
yes. i have thousands, but can't take any advantage of it.
i also have many Debug BIOS for SM with C0 support. but without ES BMC Firmware you can't flash it.
When i make the Asrock w790 ws bios with this mayby working?That dont have BMC.
BMC is only problem at Supermicro with Root of Trust Firmware.
i doubt you get over POST code "cd" but good luck !
MCU C06F2 fits also C06F1 EMR A0 - same cores ( microcode ext.header)
this is just extraced that way by MCU Extractor.

Then like this also good?
I was referring to this post https://forums.servethehome.com/ind...-xeon-emerald-rapids-emr-sp.46162/post-452414 between you and arabus
I don't know if I misunderstood, but I never saw a reply by arabus saying he received it.
me not , exactly that is what i mean.
the one "defective" is still for sale.
