Thanks, that's good to know and I will try to specify the rom.<br>
<br>
In the mean time, do you know which bios revision your card has? The other revision is <a href="https://www.techpowerup.com/vgabios/185395/msi-rx480-8192-160719" rel="noreferrer" target="_blank">https://www.techpowerup.com/vg<wbr>abios/185395/msi-rx480-8192-16<wbr>0719</a><br>
<br>
So is it 113-MSITV341MH.151 or 113-MSITV341MH.152 ?<br>

I have that msi rx480 card working with pass through.<br>
<br>
Note I had a much easier time using the uefi bios. I am currently<br>
specifying a rom file in my XML for my video card but I don't think<br>
that's entirely necessary.<br>

Who is the manufacturer of both your AMD cards? So far as I<br>
understand<br>
things, its up to the manufacturer of the card to provide the<br>
appropriate ROM<br>
to suit the configuration of the card. Its likely that a ROM/BIOS<br>
update may<br>
fix your RX 480 card. Do both cards work under a pure Windows<br>
environment?<br>

That's a simple question but a difficult answer to get a pure<br>
Windows environment working again ;)<br>
<br>
Anyway, I got the following results after using GPU-Z under Windows:<br>
The RX480 is a MSI Gaming X 8G:<br>
