The EVGA GTX 780 Ti SC ACX works at a 1006MHz base clock, while the reference GPU base clock is set at 876MHz. Nvidia's GPU Boost 2.0 takes the average GPU clock to 900MHz for the reference GPU and to 1106MHz for the SC ACX card. The overclocking potential is very good considering that this is a factory overclocked card. Using standard voltage and AUTO fan settings we managed to push the GPU 130MHz over the factory clocks. Memory overclocking is vital in any attempt to squeeze out more performance from a graphics card. The memory produced average results with a total 150MHz (effective 600MHz) overclock.
