Before I started this project I had a stable system running a threadripper 3970x, 256gb of 3600mhz RAM (8x32gb), and an Aorus Extreme motherboard. All was well, and I ran with the default “Profile 1” XMP profile, which ran at 3600mhz and 1.35v.
A bit of background, this system is a VFIO workstation / server / lab and lives at the office. I used to run ESXi, but am in the process of switching to Proxmox to match my lab at home.
Since the pandemic started I may go months at a time without going into the office. This prompted me to finally cave and go buy a TRX40D8-2N2T server motherboard. Really this whole project was to get true OOB access via an IPMI interface so that I could do offline maintenance on the box.
This board has been great so far. The one problem that I’m having is that the system won’t boot if I enable the XMP profile. The system won’t post and I get a diagnostic code of “Ad”.
Have any of you tried enabling XMP on an Asrock Rack board? I reached out to Asrock a few minutes ago to see what they say. Their business product support is pretty good, I expect to hear back from them tomorrow. I’m curious though what other’s experience has been with XMP on these server / workstation boards that use consumer CPUs.
