I previously had my machine running, with my AMD Vega 64 passed through.  As I was having issues with one stick of my 16GB RAM I removed it, leaving me with now only 1 x 8GB.

 

I have tried to set up a new VM (after deleting the old one) but cannot pass through my Vega 64 GPU - it doesn't even show up in the list for available GPU's.  When I check System Information on Unraid I see the below, however in my machines BIOS VT-x is enabled.

 

Any idea how to fix this?  Do I need duel RAM?

You need VT-d / IOMMU enabled.  Usually its buried in a submenu of the BIOS.  It's different than VT-x

Any idea where to find it?  I followed these instructions on Asus.com to enable virtualisation.  Didn't mention any other options https://www.asus.com/support/FAQ/1043786/

Normally in the system agent section.

Thanks, that worked!
