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.

On NVIDIA cards with boost, the values discussed here are base clock. Boost will further increase clocks.



Maximum overclock on our card is 1120 MHz GPU base clock (11% overclocking) and 1675 MHz memory (12% overclock).

GPU overclocking yielded the typical average overclock for a GTX 660. Memory overclocking ended up a bit lower than with other cards because the card uses Elpida memory, which doesn't OC as well as Samsung or Hynix.

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 8.1%.
