Intel / HP latest BIOS lacks this microcode.
WTF??!?!? eBay lied to me
Good thing I checked before pulling the trigger on them.I'm currently running two 8268 ES qq9e on a X11DPI-NT with bios 3.6 and get memory controller errors when I try to populate 4 Intel 256gb dcpmms. I have am using TSV ram. Anyone have insight into if what might be the issue before i send back the optane?
Does this mean that D0 ES SPR is like the stepping 6 Ice Lake xeons and we are likely to see long term support on the W790 Ace? I was thinking of building an Ice Lake system with the stepping 6 ES or QS but it looks like using a D0 ES2 SPR-SP is better? What do you think?
no. Ice Lake D0 is production stepping microcode and latest.
606A4 - Ice Lake-SP B0/L0 (LGA4189)
606A5 - Ice Lake-SP C0 (LGA4189)
606A6 - Ice Lake-SP M0/M1 D0/D1/D2 (LGA4189)
Sapphire Rapids D0 microcode is marked as production but has successors E0,E2,E3,E4,and E5.
806F0/97, "A"
806F1/10, "HBM A" Xeon Max
806F1/87, "B"
806F2/87, "C"
806F3/87, "D0/R0" (D0 is XCC, R0 if MCC)
806F4/87, "E0/S1"
806F5/87, "E2/B1"
806F5/10, "HBM?"
806F6/87, "E3/S2"
806F7/87, "E4/S2"
806F8/87, "E5/S3/B3" (actual latest)
806F8/10, "HBM B" Xeon Max (actual latest)
Physical Chope xample:
806F8/87, "E5/S3/B3"
E5 = XCC ( 4 tiles)
S3 = MCC (single die)
B3 = XCC ( 4 tiles) + HBM

Referencing post above - just saw SPR with strange E5/S3 stepping during one of today's communications with sellers over the ebay..
(for some reasons most of them are a bit lazy to publish details about ES/QS or correct CPU pictures with product code and production date lines to derive QS generation, and consequently expected stability and functionality)..
Although prices are still beyond reach for QS..

I've asked every China-based ebay supplier (about dozen already) for a picture of actual SPR QS CPU label (to derive production date from FPO and QS generation) - everyone either keeps pretending they don't understand or dodging with sending some other information).. IMV that is a bit of a red flag, I wouldn't want to get any QS produced in first half of 2022, prefer getting Q4-22 or Q1-23 (if those exist),, worst case Q3-22 but sellers really do make this very difficult.
Perhaps it's worth just keeping an existing 8461V kindly sold by kizune, and wait for proper discontinuation of SPR by DCs while they move to Emerald Rapids.

They know what is up very well, hence the "nix verstehen" tactic. Big red flag. Money is tight even at hyperscalers for the next 2-3 years I imagine, replacement could take awhile. Unless security landscape forces their hand should a -50% integer performance critical fix become necessary. Make sure to qualify all DIMM sockets and also PCIe slots that they work after CPU swap. 50% yields of Intel 7 tells me the other 50% also have higher fail rates when subjected to a few months of intensive workloads. I like the more solid stuff hence 14nm++ i.e. no later than Cascade Lake.
strange ? E5 is final "QS", not "EV-QS"
806F8 XCC = E5
806F8 MCC =S3
806F8 XCC-HBM =B3

ok, ok, let's put it this way: it was unusual for me after months of dodging D0 (and unpleasant experience with it, not like I'm big fan of causing self-harm) and seeing plenty of E2/E3 around.
Does anyone have any experience with the Tyan S5652 and the Sapphire Rapids ES/QS parts? Would a D0 stepping part work in that board?
NO
i wrote somewhere that Tyan supports ONLY E-Stepping ES/QS/PRD processors, same than supermicro.
Thanks, good to know. It's a big thread, I did see that supermicro is no good for ES parts, but I guess I missed the comments on Tyan.
What about the ASRock Rack SPC741D8-2L2T or GIGABYTE MS03-CE0? I'm trying to find something relatively economical that has lots of usable PCIe x16 slots, and I don't really need more than one CPU. MS33-AR0 is not very interesting because half the slots are blocked by the RAM. MS73-HB1 I guess might be a decent option, but I don't really need two CPUs and with only one CPU installed presumably some of the PCIe slots will not be usable. I suppose ASRock Rack SPC741D16X-2T might also be an option worth considering, similar setup as the MS73-HB1.

ASRock C741 series supports ONLY E-Stepping ES/QS/PRD processors, same than supermicro/Tyan.
(the BIOS of ASRockRack/Gigabyte/Tyan can be modded,)
Currently ALL Gigabyte C741 boards support D0 stepping SPR-SP ES. if you update BIOS, don't update Intel SPS/ME.
edit: Intel SPS/ME allows SPR D0 up to latest BIOS
