Gigabyte GeForce GTX 670 2GB X Turbo - Overclocking

As Gigabyte's overclock is a fairly modest one, we were hoping to be able to squeeze some extra juice and higher frame rates from its card, especially as it houses an extra power phase. We fired up EVGA's Precision tool for the job, and once we'd settled on the highest stable overclock, repeated the Unigine benchmark and the Battlefield 3 2,560 x 1,600 test to see the impact.

We ramped up the voltage the maximum available, which was 1175mV, and also increased the available power to the maximum of 112 per cent. With these settings, we were able to add an extra 100MHz to the core clock, taking it to 1,080MHz. This represents roughly a 10 per cent overclock, or an 18 per cent one over stock frequencies, which is not too shabby. It's also 40MHz higher than we were able to overclock the stock GTX 670 2GB to. The claimed boost clock at this setting is 1,159MHz, but we saw it boost to 1,254MHz in use.

As for the memory, we were able to clock it up by a whopping 350MHz (1.4GHz effective) before the card begun to become unstable. This gave us a memory frequency of 1.85GHz (7.4GHz effective), a 23 per cent increase, far higher than the 1.7Ghz (6.8GHz effective) we managed with our stock sample. At these frequencies, our power draw test took our peak system power consumption up to 284W.
