Overclocking

The overclocks 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, that's why our results here can only serve as a guideline for what you can expect from your card.



Maximum stable clocks of our card are 1100 MHz core (20% overclock) and 1760 MHz Memory (17% overclock).

We see great overclocking potential from the GTX 670, despite the cheap PCB design. GPU overclocking works well, yet can not reach the clock levels we have seen from the GTX 680.
Memory overclocking seems limited, about 100 MHz lower than what we have seen from other GTX 670s tested today. One factor here seems to be the lack of any cooling for the memory chips, the PCB design might also play a role here.

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,
reached 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 13.8%.
