Ok, so yesterday i decide to back up my purchase of a 760 with a stick of 1x8gb pny ram. This would not run windows, but to my dismay, upon putting back my dominator 6gb in, it only read 1 of these sticks meaning i only had 2gb of ram. Upon trading these in for a Corsair Vengance 2x4GB i only had 4gb of ram. I can rule out faulty sticks due to both having the same problem, and it worked in every memory slot, so I can rule out a faulty slot. I've also tried resetting the CMOS jumper, and updating bios. I hope you guys can help, thanks 😀
