Single 780 Ti KPE on stock air cooling. This is a second 4930k....it stinks too...couldn't even get to 5.5g. And cold bugs at -120C. Had to go around about way with Blk clock to get close to 5.5G. I have bad CPU luck :(
Oh, and the gpu core shown on GPUz I learned is inaccurate. If you open the sensor tab of GPUz you will see the real clock. In this example I was at 1222, but it was really 1339
