Overclocking

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 855 MHz core (22% overclock) and 1410 MHz Memory (23% overclock). Really nice overclocking, especially considering this is brand new 40 nm GPU technology. Essentially you can buy a HD 5750, overclock it to HD 5770 performance levels and still have some money left for other hardware.

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 18.3%.

Temperatures

Temperatures are very low. Even with our overclocking, the temperatures are so low that it would have been no problem to quieten down the fan a bit more.
