HP?

Latest version of unraid?

Can you attach full diagnostics?

Try to enable unsafe interrupts:

Settings -> VM -> VFIO allow unsafe interrupts -> Yes

Reboot server.

Sorry it has been a while since i was able to sit down and look at it. It no longer errors out but the gpu is not outputting anything, and i know that the gpu works.

if it's not outputting any error you probably changed something?If this is the case new diagnostics is needed.

Here you go.
