Hello. Sorry to bother you, but I have been trying to overclock my i7 920 DO to 4 GHz and I can't get my system let me get past the login screen in Windows. I have read your thread about the question about the 970 SLI.
I am rocking the same Hardware as you but I have a GTX 1080.
Oh I just saw you have the extreme and I just have the gene motherboard. Is it because of that?
