Gigabyte GTX 680 Super Over Clock 2GB Graphics Card Review

We’ve seen so far that the card has a lot of performance on tap, but as with all things hardware, there is always the scope for pushing things that little bit further. With this in mind we now endeavour to see how well each piece of hardware that we get in and we think is worthy of, gets our overclock treatment to take things right up to the next level.

To test our overclocks, we decide to stick to what we know best for overclocking, MSI’s Afterburner software, along with GPU-z, Furmark and 3DMark 11.

As we can see, we’ve managed to get the GPU core clock speed right past the 1200MHz mark to 1210MHz with a boost speed of 1275MHz. Similarly we have been able to raise the memory speed right upto 1720MHz (6880MHz effective). We were able to get both the core clock and memory clocks higher in their own rights when overclocked separately, however as always, when raised together, we found the card to be unstable and would crash during testing.

Following our burn in test to ensure that the overclock was stable we then moved onto re-running all of our normal benchmark tests to see how much of an improvement was to be had from the card. What we found however was whilst 3DMark 11 showed a performance gain under both the Performance and Extreme presets, in the remainder of the benchmark tests, the card performed almost the same as it did when at the factory overclock. This leads us to believe that even though the card has got more give in its clock speeds, Gigabyte have not set them as high as they are not required to give the same performance levels.
