Every vendor has their quirks. I have a pair of ASRock Rack ROMED8-2T/BCM boards, but my M.2 NVME boot drive is no longer detected if I update the BIOS past v3.50. Unfortunately, that means no support for resizable BAR in my configuration.

I have a pair of Supermicro H12SSL-NT boards to use for my next couple builds. I might be trading one set of issues for another, but I'm optimistic they'll work well for my purposes.
