Gigabyte GeForce GTX 780 GHz Edition 3GB - Overclocking

Using EVGA Precision X, we began our overclocking by increasing the power and temperature targets to the maximum permitted (106 percent and 95°C) as well as increasing the core voltage by 63mV.

We reached a core clock speed of 1,065MHz, a 4 percent increase. This gave us a boost clock of 1,117MHz but in reality the card was hitting 1,215MHz under load. This isn't a big overclock but that's to be expected when the card already ships with such high frequencies.

Our experience with the memory was excellent. We raised it from 1.5GHz (6GHz effective) to 1.825GHz (7.3GHz effective), a massive 22 percent jump which saw total memory bandwidth increase to 350.4GB/sec.
