Problems from SLI and OC?

Hey guys,

I recently added another GTX 570 to my system and am now running in SLI. I was getting some poor performance and read that my cpu may have been bottlenecking ( even though i have a 2500k oc'd slightly). I overclocked my cpu a bit more and saw an increase in fps.

About a day later the problems started happening:
- when playing some games there is a slight bar of distortion in the middle of my screen (sometimes moves up and down).
- fps drop drastically at times
- computer goes into a loop of rebooting and won't display anything. :cry:
- a few random crashes.

Ive tested both cards separately and they work fine. Temps are fine on both graphics cards and cpu. Anyone have any ideas whats causing these issues?

Thanks

  1. Uhhh.... yeah...

    An unstable overclock. :P
    Either too much vcore or not enough. (Or else you were messing with something that really shouldn't be messed with.)
