Stumbled upon this SuperMicro board while researching parts for my new home server and wondered if anybody has tried it especially for virtualization and passthrough of GPU to Windows VM.
There are some limited threads on the board but only one person seem to have actually bought and used it but not for VFIO.
I’ve got this board. I plan to DDA passthrough an Nvidia GPU to a Windows VM but I haven’t actually set it up yet
here’s the IOMMU groups though:

Nice! Coming in clutch!
…and I had thought that this would end up in the graveyard of unanswered threads. 
Thank you very much! Pls do share your experience with passthrough on this board when you get around to it.
The groupings look good but it would probably be weeks before I can get one shipped
lol, to be honest I wasn’t having high hopes too!
