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.
i theory yes, but i don't if there is more required, proper(older) Intel RC code etc.
i have older Supermicro BIOS for B0,C0/C1/C2 but they used different cryptokey and are not accepted by RoT.
i know, there are many others, i have some of them too, but never saw them working. ( have SPR-WS C1, needs W790 board )
if you need to mod the BIOS, a chip replacement is required too, depends on the flashing tools, do they accept modified BIOS ? unknown.
my experience is they do not, butthere are other ways to flash: in circuit with a clamp i.e.
(a warning, do not try at supermicro, you can brick the board)
why not spend $60 more for a D0 ES2 which is known working ?

Yes, you are right. Spending the extra $60 to save all the headache is definitely worth it in this scenario. Unrelated question, but have any of the SPR-WS or Xeon W9, W7, W5 "X" series ES CPUs been unlocked for overclocking like their retail versions?
good question ! next please...
serious: i don't seen any of them working except a w9-3495 ( QS without 'X') which is not unlocked.
anything is possible, like at LAG3647 1st gen scalables ES, some ES are unlocked but the retail not.
Haha very funny. In all seriousness I appreciate all the info you have shared here. This is the only source of information on SPR ES CPUs that I have been able to find anywhere on the internet, so it is basically a gold mine for anyone looking to learn the best way to get one of these CPUs running. It is a big investment after all, $400 for a CPU, $800 for a motherboard, then cross your fingers that everything is stable. But when the retail price of these ES CPU SKUs are $7,200 or more, the savings makes it all worth it.
Here's a screenshot from HWINFO64. It says 3.6Ghz on up to 18 cores. Now, I haven't tested it to get it to load 18 cores at 3.6Ghz, but that's what HWINFO is saying. Maybe that's an error from HWINFO?

How did you configure the BIOS to run 3.6G when idle or on a single core?
My qvm7 + X12 Dpi N6 only run 3.0 on single core. Even when idling, no core is running higher than 3.0Ghz.
Maybe there is some performance setting I need to change in the BIOS for CPU pstate or cstate?
Thanks!
no changes other than this:
disable 18 cores.(bitmap FFFFF)
windows power plan balanced, run CPU-Z stress cpu to put load.
edit/update:
i use X12SPM with BIOS 1.0, you can not expect the same BIOS default settings.
if you run linux maybe you have to set to "BIOS Controls EPB" and "Maximum Performance"

I see, so it should work with any motherboard regardless of bios version, right?
