The title explains my problem really: gpu-z shows my pci slot is running at x1 when it should be x16.
I found this site (http://www.techarp.com/showarticle.aspx?artno=522
) which describes my problem exactly but 'peg force x1' is off on my motherboard and i'm not overclocking so the nb vcore is set to auto (I tried setting it manually to lower than 1.45 but no luck).
I've changed drivers also with no success.
I can't use the other slot because the bloody massive card wont fit.
I have no idea what else to do. Please help
