ASRock BIOS is moddable, i guess Tyan too.
give me the link of the BIOS, I'll try my luck...

It’s looks like there’s three BIOSs that have been released for this board. I’m not sure which you’d prefer so I’m posting all three. Though my guess is that the initial release will be the easiest to mod? I’d love to see QYFS or QYFQ running, though that seems aspirational.

The second one gives support for EMR.
1st BIOS: https://www.mitaccomputing.com/en/downloads/details/MitacServer/S5652AGM3NRE-2T_BIOS_4529#

2nd BIOS: https://www.mitaccomputing.com/en/downloads/details/MitacServer/S5652AGM3NRE-2T_BIOS_4584#

3rd BIOS: https://www.mitaccomputing.com/en/downloads/details/MitacServer/S5652AGM3NRE-2T_BIOS_4618#

Thank you Rollo!

try if this is accepted by BMCWebGUI firmware update

It seems that Gigabyte removed support for the Xeon 4 4677 ES after the R17 release. Many of my friends have reported that after flashing the new BIOS, they were unable to use it.

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)

806F3: if the CPU is XCC(4 tiles) it is D0, and the single chip MCC is called R0 then.

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 )

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.

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.
