OverclockingThe 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 1160 MHz core (15% overclock) and 1830 MHz memory (18% overclock).
GPU overclocking potential is outstanding and exceeds what we have seen on other GTX 670s we have reviewed previously. Memory overclocking, on the other hand, does not work so well, which is probably due to the lack of any cooling for the memory chips.
Important: Each GPU (including each GPU of the same make and model)

Overclocked PerformanceUsing these clock frequencies, we ran a quick test of Battlefield 3 to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 12.4%.
