Two things I am looking to understand with AMD cards :
A) If your motherboard has no BIOS setting /option for it, can you force the system to use the GPU in your second (or third) PIC E slot, as the primary display adapter? I have been unable to find such a feature in CCC, Radeon PRO or Afterburner.
I can confirm that my system will display from a card in the second PCI E slot. It's when I install a second GPU back into the primary slot(near CPU) that it switches the display adapters.
B) Is Powerplay (dynamic clocks/clock speed) meant to work in Crossfire mode? It works fine in single GPU configuration but seems to get disabled in Crossfire and all frequencies are at maximum speed.
Thanks
