Hi just got a new mobo, m5a99x, and gpuz, cpuz, aida all show pci express to be at x1 with a capabilty of x16.

Works fine in my old board and I tested at gtx 260 in the new board and it was at x16.

Tried reseating, cleaning etc, what is going on?

Btw i tried this in both pci express slots and again both at x1, specs in the sig and there seems to be no options in the bios for pci express link, bios also updated.
 
So you have gone through the UEFI? I'm pretty sure there is something in there about deciding how the lanes are handled. Are all the power connections securely made?
 
I think it is actually the gpu, just tried it back in my old mobo and it wont even boot no matter what you, stuck in the gtx 260 perfect every time, again with the new mobo amd card stuck at x1, gtx 260 is at x16.

Ive had a few other problems with this card which include having to manually set the 2d clocks to avoid artifacts, common problem apparently, and the driver crashes numerous times which was only fixed by setting the cards proper clocks to constant( or just not very low like the powerplay settings do)

I cant find anything in the bios for the pci express lanes, on for the frequency, pce express spread and few other bits and bobs but not for the lanes.

Anyone have experience of xfx rmas?
