Hey guys, I've been trying to squeeze a little bit extra out of my 770s. I've been told that the Core clock isn't going to budge too much since it's about as high as it can get, but I can get a decent performance boost if I bump the memory speeds up a bit. I'm currently running dual EVGA Superclocked cards with ACX coolers

 

What sort of numbers should I be aiming for in terms of voltage, memory offset and core clock offset? I had something the other day which I thought was decent, I think it was +400MHz memory offset, +100 core clock offset, and it looked fine running a benchmark in Unigine Valley. Temps at around 70 degrees, then the whole thing locked up on the last scene
