Weirdest computer issue I've encountered

[wagex]

i never thought to mention is it possible one of the traces got scratched on the back of the board when it was being moved?... or on the front?

So it was a bad board.

The new one is installed, and SLI is working.

Something of note though, with the swap to 2133 memory, I'm having to run my CPU on 1.29 vcore to get the same overclock as before. I was 1.19 earlier, but even at the higher vcore, temps are way better.

There is someone over on the ROG forums who had same problem,but i think it was fixable with a bios flash done twice or something,Ill see if I can find it..Glad you got it going tho
