Device Manager > Display Adapter > (right click) on your Graphics Card > Properties > Tab: "Resources"

If you only see "Memory Range" there, then your reBAR is not working.
You need to see "Large Memory Range" x1 there.


GPU-Z seems to be working fine here - I think this is BIOS related.
I turned it on, and AMD Radeon Software shows that it's enabled, but there is no "Large Memory Range".

If Radeon Software lets you enable this feature, then it is indeed working just fine for you.

You can double check with the latest GPU-Z (2.43.x) and looking at the "Advanced"-Tab,
and then select "PCIe Resizeable BAR" from the dropdown list.

That's the thing. GPU-Z shows it's disabled.

Post screenshots of GPU-Z (1st Tab and Advanced PCIe) and maybe @W1zzard can see what is going on.
Show what device manager resource view is showing as well. Maybe we can figure out what is happening.


edit: this may be related to XFX or RX 5600 XT - continue in your thread, rather than this one here.
