Gainward GeForce GTX 770 Phantom OC 2GB Review

Taking a look to see how far we can push the overclock, we find ourselves firing up our trusty friend; MSI AfterBurner and immediately seeing how far we can push the GPU core clock speed from its already pre-overclocked state. With new technologies from Nvidia, overclocking is even easier and we are hoping to see some good results from this card, based on the temperatures and power delivery that we saw in the charts on the previous pages.

From the initial 1150MHz speed that the card shipped with, we were able to push it even further to 1225MHz giving us a 6.5% increase and without stopping there, we also focussed heavily on the memory speed, taking it from its stock speed of 1753MHz up to an amazing 1990MHz resulting in a 13.5% increase and an effective speed of 7.96Gbps. To say that these figures are nothing short of amazing is an understatement to say the least. The cooler has certainly helped us to get these figures today.

With these overclocks in place, it was time to fire 3DMark 11 back up to see how the score was affected, if at all. With an initial score of 3906, the overclock that we applied allowed us to get a 3DMark Extreme score of 4185, showing a 7.14% increase thanks to a small amount of tweaking within our chosen overclocking software.
