has anyone seen any w9-3400x series es/es2/qs cpus floating around?
no but forget ES C0, C1, C2). the microcode is not included even in oldest official BIOS.
stepping D0 will work (except Tyan)

D0 is good, mostly ES2. if you find a board with BIOS still included microcode for stepping D0.
Tyan BIOS only includes Ex stepping microcodes. Gigabyte still includes stepping D0.
i don't found any (official) BIOS with support of the B0,C0,C1,C2 steppings.
i expect many DDR5,PCIe 5 issues with early SPR ES.
QYFQ ( yes, i have currently only one working RDIMM Kingston KF556R36RB-16 @4800)

ice lakes ES2 become cheap, even from ebay us.
you need asrock or gigabyte motherboard, or supermicro but:
works only on supermicro single socket with BIOS 1.0(hardly to find) and X12DPi with BIOS up to 1.1c
on the first picture it looks like the QVM7(8360y ES2) can go x36 all cores, but it is only an illusion(greetings from windows task scheduler)
but if we disable 18 cores QVM7 can do x36 all cores.

only ? the max. turbo is reached with only 1-2 cores on most processors.
max. 1 MB
(dl & install irfanview and reduce file size, save as jpg, percentage quality down from 100% to x until it fits)
Hi, anyone knows the TDC of a Xeon 8273CL? I am just trying to see if I am lucky or I still have to mod VRM to get it work. I am with X11QPH+ so.... tbh I can't even seem to be able to locate the pins for modding VRM 
no VRM mod required. but some SM BIOS have issues. if your POST stops somewhere, report the code.

A couple of questions for you regarding the new Sapphire Rapids ES CPUs that are out in the wild. I will be asking about the SPR-SP ES CPUs specifically:
1.) You say to avoid the Supermicro X13 motherboards as they use RoT, but you have a QYFQ CPU running on a Supermicro X13 board? How is that possible? Did you replace the BIOS chip on the board manually or were you able to flash this board back to BIOS version 1.0?
2.) You say that Gigabyte C741 motherboards, like the MS03-CE0, are the best for these Sapphire Rapids ES CPUs. Do you know which BIOS revision for these boards still supports stepping D0? The only two BIOS revisions I see on Gigabytes website are F10 (February) and F13 (March). If it needs to be a BIOS prior to F10, do you have access to it?
3.) Do you have any information regarding Asrock C741 motherboards and stepping D0? I have had good luck with them in the past, but have only seen Supermicro, Tyan, and Gigabtye mentioned in regards to Sapphire Rapids ES CPUs.
I appreciate all the info you have given us so far on this topic seeing as the SPR CPUs are still so new.
i have a (unofficial)BIOS allows bring up(ME) of ES with stepping D0 microcode.
edit: flash back from BIOS 1.1 to BIOS 1.0 is rejected by IPMI/SUM, if you got a MBoard with BIOS 1.0a the downgrade should work.
i have replaced the BIOS chip with a SOIC8 SMT socket to be safe for the future.

BIOS F06 is OK, but F10 still uncludes D0.(cpuid 806F3)
newer BIOS without this MC can be modded thought.
BIOS F13 still includes microcode for stepping D0

ASRock Rack: no BIOS download available,but i think same.
edit: now checked ASROck C741 BIOSs - missing D0 stepping microcode.
Tyan first BIOS does NOT include microcodes other than E-steppings.

Appreciate the quick replies as always. Good to know that even the latest Gigabyte MS03-CE0 F13 BIOS still has support for microcode stepping D0. Also, since the Gigabyte BIOS files can be modified, does this mean someone could add support for earlier microcodes like B0, C0, C1, C2? Or not because there are no BIOS files in the wild that includes these early microcodes?
The reason I ask is because there is a particular "off roadmap" SPR ES CPU that I have had my eyes on. The specs are as follows:
SPR-SP ES? ?? (QXP4) 44C/88T 1.4 GHz 82.5 MB 270W
Regardless, seems like Gigabyte is the way to go on motherboards for SPR ES CPUs unless you want to take a soldering iron to an $800+ motherboard to add your own SOIC8 SMT socket.
