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.
Clocks listed here are base clocks; NVIDIA Boost will further increase clocks.
Maximum overclock of our sample is 1185 MHz GPU base clock (18% overclocking) and 2000 MHz memory (33% overclock).
Wow! These are pretty impressive overclocking results. It's been a while since I've seen a dual-GPU card overclock that well. With such a big memory overclock, the card should be able to overtake everything else on the market. Having massive memory overclocking headroom also helps a lot here. The great memory OC is only possible because ASUS chose to use chips from skHynix; Elpida chips, which we've recently seen on many cards, won't go anywhere near those clocks.
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 18.7%.
