Galaxy GTX 770 GC 2gb - Need more voltage!

[y0bailey]

Alright team. Loving my new Galaxy GTX 770 that I grabbed off the hot-deals new.

I am bored and sitting down to overclock, and need some more voltage.

I slapped my Arctic Cooling Xcellero III on there and it never gets above 55-60degreesC when hammering it with Kombustor or the like, therefor I feel like I am voltage limited on my overclock (right around 1300mhz core). Not gotten around to memory overclocking much yet.

I have used both Precision X and MSI Afterburner and neither let me get above 1.212v.

I dabbled around in Kepler BIOS editor and kinda chickened out after a few flashes and no improvements in reported voltage.

Anyone have any ideas?

Custom firmware is pretty much the only way past the NV guideline voltages. I couldn't make any recommendations myself, but I will say that Skyn3t over at the Overclock.net forums has done some great work creating and supporting his own methods of circumventing such limits.
