A0 microcode is unsupported since 2019, so YES.For the 8280 ES.. any known problems. Is the A0 stepping subject to MDS vulnerability?

Supermicro non OEM X11 LGA3647 boards support TDC up to 228A (default) need VRM modd for 8272CL.I know that the board is advertised to support CPU up-to 205W and that the 8272CL is at 195W. My thinking is that it should be working, but before buying, I also came across this thread and saw the TDC 255W etc.
Is this the same for 8259CL ? Looking for a cheap path to lots of cores and not slow single core. Any other alternative in the price range of 250-300$USD on ebay you think of? Or, for a total noob, is this easy to the the VRM mod or I would need to send the board to an expert like you?Supermicro non OEM X11 LGA3647 boards support TDC up to 228A (default) need VRM modd for 8272CL.
yes. 8259CL TDC=255AIs this the same for 8259CL ?
buy Adafruit MCP2221a or ElmorLabs EVC and check this.Or, for a total noob, is this easy to the the VRM mod or I would need to send the board to an expert like you?![]()
Just bought the ElmorLabs EVC linked in the VRM Mod thread. Hopefully, i'll be able to do the Mod :Oyes. 8259CL TDC=255A

only Gigabyte and ASUS W790 boards (yes realy)Just came across this thread at the perfect time, was about to buy an ES Xeon with D0 and was just expecting it to work with any motherboard.
step id 4 is cpuid 806F4 = stepping E0Anyways I was looking at a Intel Xeon Platinum 8470 ES (CPU Z below from seller) and wanted to use it with a ASRock Rack SPC741D8UD-2T/X550 motherboard, I don't see the stepping code so I'm hoping their won't be any compatibility issues b/c I need micro atx motherboard for a project I'm working on, am I missing something or will this work without any funky workarounds

thank you very much I appreciate itonly Gigabyte and ASUS W790 boards (yes realy)
Tyan, Supermicro and ASRock Rack support only E-Stepping processors.
step id 4 is cpuid 806F4 = stepping E0
should run on any C741 motherboard.
Thank you man! Saved my biscuit there from spending another 700$ on ES cpu. I was going to mod the bios for X13SEM-TF but it appears that I can hold off with just getting E0 stepping.only Gigabyte and ASUS W790 boards (yes realy)

you can not mod supermicro X13 C741 (RoT protected) BIOS. if you change just one Bit, the security validations fails and the BIOS is restored from Backup.I was going to mod the bios for X13SEM-TF but it appears that I can hold off with just getting E0 stepping.
I've modded dual bioses on HP but that might be different with SM.you can not mod supermicro X13 C741 (RoT protected) BIOS. if you change just one Bit, the security validations fails and the BIOS is restored from Backup.
the check is cryptographical nature with Private Key. if you have the supermicro Private Key you just have to re.sign the modded BIOS.I've modded dual bioses on HP but that might be different with SM.
Is RoT check against second bios chip? Have you tried to mod two at same time?
Oh thats rough. I am glad that I pinged you here before getting burned on any attempts.the check is cryptographical nature with Private Key. if you have the supermicro Private Key you just have to re.sign the modded BIOS.
but i doubt you will get the PK.
edit: after BIOS restore of the BIOS flash, the content is validated again. no chance.
i have MS33-AR0 and a QYFQ should be not that different from MS73, i create installatin media for W11 now and check whats happening, hold the line.it would be great if you could point me to another place.
USB media with Win11 booted but i got no picture with BMC VGA monitor.So far, I am running Windows 10 Pro. And now, I'm trying to upgrade it to Windows 11 Pro, but I can't proceed.
When I burn the *.iso file onto a UEFI USB and boot it, I see a BSOD before even seeing the installation screen. The main error contents are as follows.
Stop code: IRQL_NOT_LESS_OR_EQUAL / What failed: ntoskrnl.exe

no, you should only see "PC currently does not meet the minimum requirements to run Windows 11"Could it be due to the absence of the TPM module?

after installation of a PCIe GPU i got picture and tried to install..
"PC currently does not meet the minimum requirements to run Windows 11"
MS33 BIOS support TPM v1.2 only, so i think this is the first issue.
i know on the ASUS W790 Ace & SAGE SE and QYFQ windows 11 is possible, BIOS supports TPM 2.0( without module )
no, you should only see "PC currently does not meet the minimum requirements to run Windows 11"
create USB media with microsoft mediacreationtool
edit:
w. only TPM 1.2 you can update to w11 from w10 with a registry tweak
your media is corrupt. create USB directly media with mediacreationtool, NOT burn iso to usb diskHowever, the difference between RolloZ and me is that I could not even see the message. ( = "PC currently does not meet the minimum requirements to run Windows 11" ) When that message appears, we can force install it by modifying it a little with REGEDIT. It's true, but...
This is what happens when I try to install W11 on my MS73.
After completing the BIOS post -> Press the F10 key to select the OS USB device -> The loading part spins around and then a BSOD appears immediately.
your media is corrupt. create USB directly media with mediacreationtool, NOT burn iso to usb disk
Yes, I like the stock OS, so I tried it first using the program provided by MS. But there was the same error.your media is corrupt. create USB directly media with mediacreationtool, NOT burn iso to usb disk
tried the USB in other PC ? i used sandisk 128GB stick.Yes, I like the stock OS, so I tried it first using the program provided by MS. But there was the same error.
That didn't work, so I downloaded the ISO file from the program and uploaded it to USB using Refus, but the same problem occurred.
After that, I burned several tweak OS iso files for several days, and this shows the Windows installation process
but when I reboot after that, the IRQL_NOT_LESS_OR_EQUAL error message welcomes me again. Instead, the difference from before is that the What failed: ntoskrnl.exe message disappears.
W11_22H2 doesn't work, so I tried using W11_21H2, but the problem still persists. This is really sad.
