NVIDIA GeForce GTX 780 Review @ OCC

Firing up the latest beta version of EVGA's PrecisionX overclocking and tuning utility, I increased the fan speed to the maximum level; this is to provide the best possible cooling scenario as well as looking at the worst noise levels the fan would ever deliver. I then maxed out the voltage and started increasing clock speeds. The first adjustment netted a dynamic boost clock of 1100MHz on the core for a hefty 200MHz boost over the reference boost clock. Further tuning got the boost clock up to 1202MHz, which proved stable through all of the gaming tests. I could run higher clock speeds through some of the games but not all with 3DMark being the primary failure point. Even so that's about a 34% boost in clock speed on the Kepler core. The memory was a lot less forgiving when it came to overclocking, only reaching 1612MHz or about 7%. Every bit helps when you chase benchmark scores.
