Been looking around for a few days and I can't seem to figure out how to get this issue resolved. If I have my video card in one of the top two pci-e slots I get the Dr. Debug "d6" error which basically means its not detecting my video card. If I put my video card into my bottom pic-e slot I can start up fine. I have read several places with people having this issue but never a resolution. Is it just a bad board that I need to get RMA'ed? I just think its funny I've seen this issue a lot of other places online and didn't think we all had two bad pci-e slots. Any ideas?
The PCI-e lanes from the top two PCI-e slots are connected to the CPU. The PCI-e lanes from the bottom PCI-e slot are connected to the PCH (chipset).
The CPU might be faulty. You could have bent or broken socket pins. Or a faulty motherboard.
Or something less probable: The first slot is connected via 16 PCI-e lanes, the second via 8, and the third via 4 lanes. If the graphics card has some problem in line 5 to 8, it might still work in the last slot but not in the others.
