Overclocking (GPU BOOST 2.0)
For overclocking our NVIDIA cards we will be using EVGA's Precision too (ver 4.2) as this gives us all of the options we require.

Above is a screenshot of the actual overclock we achieved via Precision. With both the power and temp targets maxxed out and an additional 12mv added to the core, we managed a 100% stable 1280MHz boost speed based upon an initial 130MHz to the reference speed. Despite the GDDR% memory being highly clocked already, we still managed an audacious extra 169MHz giving us an effective memory speed of 7344MHz!



This is a fantastic result by any standards and goes some way to proving GPU BOOST 2.0 is an excellent method for overclocking, especially if you forgo the pop-up warning (above) that displays when unlocking the voltage adjustment which only allows a 12mv increase over stock.



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. As you can see, this overclock gave our Heaven 4.0 score a respectable boost by almost 200 points.
