There are two ATX 12V power connectors on the bottom right corner of the board, this same as the asrock w790 ws. on Asrock w790 ws, at least one of them needs to be connected otherwise it will no work. Have you connected them?

Good point, i forgot to mention it before, but yes , in most tests i connected them all of them. First time ever i connected 4 8-pin power cables in a motherboard from a single psu. I also tried several different possible combinations, just to see if it would make any difference. But in this case no, unfortunately still F.F.
It is empty right now. Buying stuff testing it and selling was just a hobby, I am not an entrepreneur. And after latest tax changes any sell of any item that costs over $600 will make me to pay a lot of taxes unless I literally start tracking what I bought for what price, did I get any profit for re-selling it after I don’t need it anymore, what is the exact profit was and what taxes should I pay from it. Before that change it was easy - just at the end of the year roughly calculate the amount of extra money I have on my hobby account, apply the tax bracket percentage, add it to the income tax and I’m done. Now it’s like a second job to do all the accounting. Not worth it anymore. So if I will ever sell anything it will be a cheap stuff. Like I’m about to move away from the ddr4 systems altogether and going to dump my collection of second generation Scalables and some Rome generation Epyc’s.
W790-ACE is Intel® Socket LGA4677 for Xeon® W-3400 and W-2400 Series Processors*, but you use xeon Scalable ProcessorsOk, i finally got myself an Asus Pro WS W790-ACE and tried all my available processors on it. Bottom line: the E3 stepping processors do not work with any of the available BIOS. Tested processors:
Q16Z Xeon Platinum 8461V stepping E3 - stops at code 00
Q0MN Xeon Platinum 8468 stepping E3 - stops at code 00
QY36 Xeon Platinum 8480+ stepping C2 - stops at code 04
Looks like only D stepping processors working with this motherboard. Will have to return Asus - which is quite sad, the deal was good and the motherboard is in an new open box condition. And i really like the layout and features. Such a bummerNot sure i want to spend money buying D0 version of processor - will probably just stick with the tested and tried Supermicro board for now.
maybe you have not recognized we run SPR-SP stepping D0 ES2 processors on ASUS W790 and ASRock W790 WS motherboards.
But why can run？ The spec just say support W-3400 and W-2400 Series Processors
for some reason they kept the D0 microcodes, and stepping D0s seem to be hermaphrodites.
It is a normal situation. You need to tune FAN mode. For example, as there I noticed:
LGA4189 socket P+ под Xeon Scalable Ice Lake-SP (4189-4) [2] - Конференция iXBT.com

supermicro LGA4677 motherboards doesn't support D0
its currently unclear if they can run E0 steppings.
I made an official request to SM technical support and they clearly answered that it does not support
I wrote to them in this style.
Does the motherboard's X13 support ES processors? they told me it doesn't support.
Maybe I wrote it wrong,I also didn’t understand their answer because many in this thread have ES cpu and they work great
i expected that answer:
if you run ES and have issues, supermicro does NOT support you.
intel provides no support for ES after lauch of processor series.
all who got ES official from intel can request QS for free.
if they would say yes you may ask for help on issues.
And no motherboard manufacturer will help you with problems with an eng.sample.
QYFQ on X13SEI-F (only BIOS 1.0)
supermicro removed microcode and actively block non E stepping ES)
( we see on gigabyte motherboards this is not required )
