When I install my GPU in the top-most PCI slot (closest to the processor - PCIE2), the computer will not boot, not even to BIOS. The fans turn on and that's it. If I move the GPU down to the next slot (PCIE5), the computer boots up and runs beautifully.
This is my RMA replacement board. My first board did the exact same thing, which is why I RMA'd it. Am I missing a setting in the BIOS or something? I would really like to be able to run my GPU in the top slot for better airflow.
GPU = PowerColor AMD Radeon R9 280X OC 3GB
MOBO = Fatal1ty Z87 Killer
