i have the following problem:
Now, to clarify: YES, i did plug in the Vega card in the primary (top) slot, it is running with pci 3.0x16, while the r9 290 is running with pci 3.0 x8. No, i can't just remove the r9 290 card, i require its output to power my monitors.
So i would really like to know what i have to do so my vega is treated as the primary graphics device. I didn't find any corrosponding bios option for that.
Thanks for your time.
