What are you guys using to overclock your Nvidia kepler cards?

I did the 1.3v unlock via Afterburner and cmd and applied the load line calibration fix. The problem Im having now is that whenever I apply too high of a core voltage, the GPU clocks throttle Sad

Im using Kepler BIOS Tweaker 1.27 to tweak my own BIOS to raise the power limit. But no matter what power settings I put, the clocks seem to throttle. This is what my power table looks like:





I managed to get the card stable at 1320Mhz with 1.25v. If I raise the voltage, the clock throttles and dips to 1280Mhz. If I lower the voltage, my overclock becomes unstable.

Any tips?

You need to unlock the power limit also, your card needs more juice after official 1.212V max voltage. There is Skynet OC bios for 780s in OCN that has everything you need. I would not go over 1.3v with reference 780, not even with watercooling.
