The GTX 760 Phantom  is factory overclocked and the GPU clock is 1072MHz, while the memory is clocked at 1550MHz. The reference clocks are 980MHz and 1502MHz respectively. We didn’t have much luck when we tried to overclock the GPU,  as we managed to boost the base clock by 20MHz, which was still enough for a top clock 112MHz higher than the reference clock.

Our memory overclocking test was a lot more eventful. We managed to push it up to 1800MHz and this resulted in a 4-percent performance gain.
