Does anyone have any good recommendations for an epyc server grade motherboard that can use 3x3090? My current motherboard (strix trx40-xe) has memory issues now. 2 slots cause boot errors no matter what memory is inserted. I plan to sell the threadripper. Other option is to just swap out the current motherboard with a trx zenith extreme but I feel server grade would be better at this point after experiencing issues. Is supermicro worth it?

If you're just going to stick to 3 GPUs. Then a lot of consumer gaming motherboards would be more than sufficient. Checkout the z270, x99, x299. If you really want epyc go to ebay search for "gigabyte mz32-ar0 motherboard" Majority of them are going to come form China and they are all pretty much used. If you have plans to go even bigger then I say go for a new wrx80

I have this motherboard - a big downside is many of the PCIE slots will overhang into the RAM if used for a GPU. I can't use two channels in my current ML machine because of this, and I have single slot 4090s.

It might not be the answer you are looking for, I would take a look at components published by System76/Lambda labs such as this to pick the one that would suit me: https://github.com/system76/thelio/blob/master/Thelio%20Comm...

Heh I went the opposite direction from zenith to ASRock tnt

Are you on the latest bios? I have had good results flashing the "E" bios in the TNT folder based on the FTP site mentioned here
