pci stuck at 8x with GTX 680, and stutting in games and vids..( SOLVED) - Page 2

Set to Gen 3, F10 to Save then reenter the Bios and see if it still shows 8X for the Link Speed,

if still does

- reset the bios ( rinse and repeat )
- or even check to see if there is a bios update.
its either something with the Mobo or the card itself since the 8X is being reported at the Bios level.

The top slot is definitely x16 compatible, and the card obviously is. I wonder if the motherboard is defective, or possibly the CPU isn't seated properly. All it takes is one faulty pin connection for the board and card not to negotiate a x16 link.

If you could get a hold of another GPU and try it out, it would at least rule out the GPU as the problem.

gen 3 8x is the same as gen 2 16x so you shouldn't seen any performance issues with your gpu anyways unless its running at gen 2 8x check and see what gpu-z say its running at

GTX 480 is running GEN 2 16x which equals 8x GEN 3 that the other cards are running. Seems you're stuck at the max bandwidth of 8x PCI-E 3.0
