I was having trouble with a UD3P, would get bsod with any OC, ran fine before. Switched out all hardware, tried different case thinking it was a wire grounduing out. Today i get a new UD3P (not an RMA, ordered a new one), put everything together and same thing, boots fine at stock only. tried 2 cpu's 3 sets of ram, different gfx card, 2 different HDD's one with a fresh install, flashed bios. Left the back off of the case to have axcess to all case wires, I tried unplugging fan wires 1 at a time, restart try different wires, and still will not oc. I am stumped. Anyone have any ideas what may be causing this?
