I've got it marked as enabled on HWInfo64 screen as shown previously on this thread (page 133):
QS might be a bit of a gamble, though, not as bad as ES but still...
But I had an incident with LGA4677 CPU0 socket (x13DEI), one of plastic nut holders broke off from cooler (which is not a problem by itself since nut can still be used to tighten the heatsink base on the same bolt), I've picked all the fragments (I thought) from the bottom underneath of it but as it turned out one tiny fragment was stuck inside the heatsink and fell off onto the socket during the installation, I didn't noticed that and started tightening, more than a half way through it felt wobbly so I've decided to remove it and check just to be safe (as at that moment I've assumed it's just strange spring reaction to tightening).
black plastic was on it preventing from right seating and folded 3 pins in one of those red-marked areas (can't remember exactly, and base pic is googled from different MB)
Good thing intuition was triggered and I didn't go for full tightening (would have to throw MB away).
So had to use microscope and wooden tooth stick (those sold in packs of hundreds in pharmacies) to gently fold pins back in right position without breaking.
Previous (unrelated to issue of potential socket damage) CPU was ES - 8468V with D0 stepping, didn't have any life at all (although has some challenges with tightening in the beginning, was overly cautious and wasn't tightening it to the end until sensing right resistance level, good thing RolloZ170 brought some more confidence), which even after right seating was always displaying FF boot code (no any boot).

first check the production unit, then we talk.
SMX/AMX/VMD can be default enabled or disabled in different BIOS.
AVX512 supported says not ALL instructions are supported, same at AMX,

According to intel's page, that code sample was written for sapphirerapids, so it should only require AMX-TMUL: Code Sample: Intel® Advanced Matrix Extensions (Intel® AMX) -... - AMX-COMPLEX is for graniterapids and should not be needed for a sapphirerapids-oriented demo
Kizune mentioned that the features disabled in bios should be listed as red (supported, but disabled), not grey (unsupported).
I can give it a go of enabling SMX and TME in bios in a little bit, but those are the only two that have explicit options in supermicro's bios. There is no option for enabling/disabling AMX.
I can also give it an attempt with newer OSes (at least win 11, which seems to be what everyone else is testing with), though it will take a bit of time to set that up, but I'll try to report back on that later today.
The version of win10 that I got the screenshots in is this build from a few weeks ago September 12, 2023—KB5030211 (OS Builds 19044.3448 and 19045.3448) - Microsoft Support

Hm, having trouble getting win 11 to install on this system. It errors out during the installation process and drops all the drives off their busses. The win 11 install environment doesn't actually exit or reboot at this point, but it fails to rescan any of the drives until I reboot. Didn't happen with the win10 installer though. Can't devote too much time to debugging it right now since I'm busy working, I'll investigate some more in the evening.
Continuing the discussion as per RolloZ170's suggestion here: https://forums.servethehome.com/ind...61v-e3-evqs-on-x13sem-x13dei-vs-x13sei.41734/
Tried to run statistics check on LGA4677 Xeon ES/QS Sapphire Rapids ebay sales and trends (mostly towards QS due to compatibility requirements)
@Kizune pretty much dominates the market without significant competition, practically holds monopoly (on actual sales)
All Chinese suppliers keep charging crazy prices measured in several $Ks for QS stones which can easily fail within a month and aren't covered by warranty not to mention exposure to stability problems.
Perhaps there's something wrong with me and I don't understand how used hardware market with fast technology depreciation works anymore.

Does anyone have info about what accelerators are available in Sapphire Rapids 8469C (QS / Q17M , manufactured in May-22) ?
Feels like ebay seller does best effort to communicate and with sending detailed images (of bare CPU + some HWINfo on listing) but without technical expertise and motivation on that side I can't get this info from them.
thanks.
p.s. this page mentions some flags but IMV there's nothing new

this ist 'C'onfidential SKU for select customers(OEM)
ask for a HWinfo Report
QAT looks like this
Code:
PCI Bus #232
Intel 4xxx Accelerator
[General Information]
Device Name: Intel 4xxx Accelerator
Original Device Name: Intel 4xxx Accelerator
Device Class: Co-Processor
Revision ID: 30
PCI Address (Bus:Device:Function) Number: 232:0:0
PCI Latency Timer: 0
Hardware ID: PCI\VEN_8086&DEV_4940&SUBSYS_00008086&REV_30I guess source of confusion is coming from what I read on ebay, some sellers advertise their QS having model numbers starting with Q1xx but some publish actual pictures of units having model number in SRxxx format
Like those two SRM7J and Q17G are both advertised as 8490H QS (even having closely similar production year/week: 2022-May/June but different factories), in both cases sellers say these are actual pictures (leaving out the question of trust of course).
