mak1e sure the mb reading both cards at 8x speed using gpu-z to read them. the other card should be in the white pci slot. also try switch the pci video bus speed from 3.0 mode to 2.0 mode and see if it the multiplex chip on the mb that having an issue.
I set PCI Bus speed from 3.0 to 2.0, and all issues have seem to be resolved. Seeing as my motherboard is supposed to support PCI Express 3.0, I should bring this up with Asus, correct?
