Hi,

Here's my system:

Asrock Formula/AC

Intel Celeron 1850

Kingston DDR3

XFX R9 390 Graphics

When using the XFX R9 390, the screen won't display anything. I've plugged an older AMD workstation GPU - it works fine.

When I plug both GPUs, I can still boot windows, the driver manager can find the XFX, but I can't use it.

I've already updated to the latest bios version (2.10).

Any idea / advice what's going wrong here?

Thanks!
