For overclocking our NVIDIA cards we will be using EVGA's Precision too (ver. 4.1) as this gives us all of the options we require. Should you desire, ASUS' own GPU Tweak is equally good.



Above is a screenshot of GPU-Z showing the reference (factory overclocked) speeds and reference boost clocks. We have also included the ASIC rating of our sample. The ASIC rating basicly tells us how good the overclock will be. The higher the ASIC rating, the better the overclock is likely to be, particularly on air cooling at a given voltage. Average ASIC readings for our GTX 770s range from 70% to 80%. As you can see from the screenshot above, today's sample is very much within that average.

In truth, we are still dubious as to the real value of this reading but time will tell. As we have been asked on numerous occasions to include it in our reviews we felt it only right to show it although please take any of these values with a pinch of salt until we can confirm whether it does actually mean a higher or lower overclock will be achieved.



The overclock for the ASUS GTX 760 Mini was average. It wasn't quite as good as the competing custom cooled cards yet easily outclassed the reference designs. Despite our very best efforts the best we could manage was an extra 101MHz on the core. This could be down to a number of factors, not least because the GPU arrives pre-overclocked. This overclock however resulted in a none too shabby 1241MHz BOOST speed. Couple this with the extra 521MHz memory overclock and the overall overclock performance of the GPU was very good.



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.
