not Gigabyte: anything required is still there and stepping D0 listed as compatible stepping in the RelNotes.pdf
Intel stopped support D0 stepping in CSI/MRC code.
i have investigated this: R18 still start POSTin with QYFQ but stops at "Chipset Initialize... EE"
the fun last long but now it is over.

i have tested stepping D0(QYFQ) and R0(Q071) = stops at "Chipset Initialize..." code EE on screen
but BMCWebGUI shows ...0x00,0x04,0x06,0x0B,0x0C,0x0D,0x15,0x7F,0x00,0x7F,0x40,0x41,0x42,0x47
i have only Q08S as a E0 stepping and that ES still works fine:
ES cpu starting with Q0 should be usable. I have tested Q0KM. But, ES numbers starting with QY (such as QYFS, QY0E, QY36) cannot be used. I think this might depend on the step size...(in r17 bios)
the Q071 is same cpuid (806f3) than QYFS but non chiplet, called R0 then instead of D0.
QY36 is stepping C2, don't work with any official BIOS.
806F3: if the CPU is XCC(4 tiles) it is D0, and the single chip MCC is called R0 then.
but same cpuid/microcode.
I have some extremely cheap supermicro x13 4677 motherboards in my hand. I would like to ask if there are any recommended CPUs that can be used for the supermicro system.
I only have 6450c and some step 3 - 4 xeon 4 or xeon 5 es
QS and prod.unit/retail.
step 3 does not work, later step 4 work. 5th gen EMR ES does not work
( with actual BIOS, there may be a Test/Debug BIOS 1.0 full of bugs with ES support )
I installed the provided BIOS on my S5652 AGM3NRE-2T, it works and it added ES support - here's a screenshot of HWInfo64 with QYFS installed:try if this is accepted by BMCWebGUI firmware update

i replaced the Xeon Max microcode(806F8/10) with the D0(806F3/87) one and disabeld ACM execution, should make EMR A0 usable too.I do not have one yet
But with the standard BIOS the QYFS was a no go so i'm optimistic.
Do you know if there is an application like one i used to edit the BIOS menu items in the times of X99 chipset? I think it was called AMI Editor or something? I'm trying to find a way to enable Resizable Bar support in Tyan BIOS. Is there a version that works with the new BIOS format?
Hi guys. I am curious about, that is C741 chipset can be unlocked to supported higher(than 350 watt) or unlimited TDP value? Overclock is not necessary.
The reason why this mind comes up I because of a special CPU with QDF "Q08U". This CPU is a step 4 es, allows all 56core 112 threads runs on up to 3.9GHz. I believe that, if the power supply will fill this beast up, it will bring an incredible performance.
Instead of the MS73 "Best performance-Maximum level" official BIOS configuration, is there are further configuration and/or modifying BIOS(s) could achieve higher/unlimited power supply?
ps: The mos heatsink components (heating management) is been modified, the CPU, power supply is enough. Don't need to worried that : )

AMIBCP. but there is no version leaked compatible with modern BIOS.
AMIBCP is not a tool to add. feature support, you can only enable hidden options.
i check the BIOS now.
TDP is managed by BIOS not chipset. CPU with TDP=385W usual work.
check something:
go to Adv.power Management, RAPL config, set PL1 Time Window to max seconds and check clocks with load,
this will allow the CPU to go over TDP for the time.
This is awesome to see!
I'm still waiting on my board to arrive so I can test. Thank you so much @RolloZ170 !
I am going to attempt with QYFQ (8468 ES) as soon as mine arrives.
On the 3,4,5 Gen Xeon I have had, this only allows the CPU to reach PL2*90% instead of 100% PL2.
Usually, ThrottleStop is used for this, but TS cannot take effect if set a value higher than BIOS PL1/PL2(even a value less than TDP) because MMIO lock function are unavailable on this platform.
Before challenging TDP(Maybe fused), MMIO or something else needs to be dealt with. Things are not that easy, Or if you think you are an expert in UEFI/OS, you can keep going.

the fused clock limits can't be exceed, but the "Q08U" should have higher clock limits and just the TDP limit prevents it from reaching.
