Just out of interest after getting the pci-e back to x16 by going to 115 if you go back into bios & drop back to 100 or 101, does it retain the pci-e at x16. ??

reason i ask is here Gfx only running at x1 I don't hav the issue but wonder if clunk's suggestion works :-
Yeah, you dont want it to stay that high. Just put it back to 100 and it should stay at 16x. If not, try 101
cheers
