For overclocking our NVIDIA cards we will be using EVGA's Precision too (ver 4.0) as this gives us all of the options we require.

Above is a screenshot of the actual overclock we achieved via Precision. With both power and temperature target sliders maxxed we hit a wall at around +140MHz on the core so we reduced this by 5MHz to ensure rock solid stability. We have more success with the memory speed, adding 549MHz which is a tremendous result.

It is possible to add a single increment of voltage (12mv) however this made no difference to the overclock of our sample.



After settling on our stable clockspeed which was verified by multiple runs of Unigine Heaven and 3DMark we benchmarked the overclock and compared it to stock results with Unigine Heaven 4.0 to evaluate the benefits of overclocking the GPU.
