Using standard voltage and AUTO fan settings we managed to push the GPU 110MHz over the factory clocks. Note that the KFA2 GTX 780 Ti HOF works at a 1020MHz base clock, while the reference GPU base clock is set at 876MHz. Adding a couple of mV we pushed the base GPU to 1150MHz. The overclocking potential is very good for a factory overclocked card. You can use XtremeTuner+ for overclocking and monitoring. Memory overclocking is vital in any attempt to squeeze out more performance from a graphics card, so we are happy to report that memory also produced good results with a total 200MHz (effective 800MHz) overclock. Hyper Boost button actually only boosts fan speed and it can help you to achieve higher boost clocks, once you pushed the base GPU clock, what is again equivalent to overclocking.
