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 1125 MHz core (9% overclock) and 1680 MHz memory (12% overclock).

GPU overclocking potential is decent and about in the middle of our test group. Memory OCs a bit less, which could be because the memory chips are not cooled as much as on other cards.

Maximum Overclock Comparison

ASUS GTX 660 DC II TOP1155 MHz1700 MHz58.5 FPS

Important: Each GPU (including each GPU of the same make and model) will
overclock slightly differently based on random production variances. This table
just serves to provide a list of typical overclocks for similar cards, determined
during TPU review.


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 10.5%.
