Value & Conclusion »


To find the maximum overclock of our card we used a combination of GPUTool and our benchmarking suite.
The overclocks listed here were achieved with the default fan and voltage settings as defined in the VGA BIOS. Please note that every single sample overclocks differently, that's why our results here can only serve as a guideline for what you can expect from your card.

The overclocks of our card are 925 MHz core (9% overclock) and 1500 MHz Memory (25% overclock). The core overclock is ok, but the memory overclock is simply amazing. Remember, on GDDR5, for every MHz real clock you increase effective clock by 4 MHz.

Overclocked Performance

Using these clock frequencies we ran a quick test of Call of Duty 4 to evaluate the gains from overclocking.

The actual 3D performance gained from overclocking is 11.4%.


Temperatures are comfortably low. Given the fan noise, it would have made more sense to trade temperature for fan noise.
