Overclocking

The overclocking results listed in this section were achieved with the default fan and voltage settings as defined in the VGA BIOS. Please note that every single 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 stable clocks of our card are 1245 MHz core (8% overclock) and 1505 MHz memory (20% overclock).

Overclocking works very well, but ends up a bit below the best results we've seen from other cards.

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 10.8%.
