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!
