The EVGA GTX 1070 FTW works at a 1607MHz base clock, while the reference GPU base clock is set at 1506MHz. The overclocking potential is good considering that this is a factory overclocked card. Using standard voltage and AUTO fan settings we managed to push the GPU 120MHz over the factory clocks. Note we have increased memory clock for 270MHz (effectively 1080MHz). This resulted in a additional 6-9 per cent performance gain in our games. The card fairly silent even after our additional overclocking.
