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 1060 MHz core (8% overclock) and 1925 MHz Memory (28% overclock).
GPU overclocking is a bit dissapointing, reaching the lowest clock we've seen on a GTX 670. Memory overclocking on the other hand works fantastically, ending up higher than any other graphics card we tested so far.

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.
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 13.7%.
