Hello guys
So my situation is this: I own a Supermicro X11DDW-NT motherboard and ES versions of Xeon platinum 8160 and 8180 (All working well on other computers, same as RAM)
Just in case: ram stick is Samsung M393A1G40EB1-CRC4Q 2400mhz ecc 8 gb. (tested with 2133 MHz 16gb, also no success)
Tried to run it only with 1 CPU and one RAM stick. But as expected - the system stops running on B7, B9, and 09 postcodes saying that no DRAMM, failure in memory learning, and else. So I can’t reach to bios.
I don’t know which bios version is currently on the mobo, but seems like it doesn’t support these ES cpu’s.
I found all the old bios versions for this mobo. Don’t know which one can support ES CPU but I would start from v2.0 or v2.2.
From my info versions lower from 2.0 can’t be downgraded due to security reasons.
Here is the link with all old bios versions and release notes for them in PDF, just in case. Supermicro X11DDW-NT Bios versions - Google Drive
I took these bios from this website. Maybe it will be handy for somebody too

Tried to flash bios through BMC but it doesn’t work, because my PC doesn’t see the motherboard IP, but maybe I did something wrong. Need some help and guidance here.
And the question is: The only way for me to update the bios - is to buy the cheapest retail CPU for this socket and update the bios?
PS. Btw: here is a great website to check if the CPU is retail and not ES, It may also be helpful for somebody
