Overclocking

Overclocking results listed in this section are achieved with the default fan and voltage settings as defined in the VGA BIOS. We choose this approach as it is the most realistic scenario for the majority of users.

Every sample overclocks differently, which is why our results here can only serve as a guideline for what you can expect from your card.



The maximum overclock of our sample is 1135 MHz (10% overclock) and 1638 MHz on the memory (15% overclock). Memory overclocking seems to be limited by the Elpida memory chips or their settings in AMD's VBIOS. While everything runs completely stable at 1638 MHz, the card immediately crashes with just an additional 1 MHz, no matter whether running a game or not.

Overclocked Performance

Using these clock frequencies, we ran a quick test of Battlefield 3 to evaluate the gains from overclocking.


Actual 3D performance gained from overclocking is 9.1%.
