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 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 1210 MHz GPU base clock (12% overclocking) and 1675 MHz memory (24% overclock).
GPU overclocking works well, but is restricted by NVIDIA's power limiter. Once you exceed a certain clock frequency, the card will drop down to base clock to avoid drawing too much power. This happens at different clocks for each card, so you have to change your typical overclocking routine. Normally you'd just increase clocks until the card becomes unstable; now, you have to carefully go up in steps, measuring performance every time to find out where the drop occurs. What makes it even more complicated is that not all games load the card the same, so one game might still boost while another drops the card down to its base clock.
Memory overclocks nicely because the card uses Samsung memory chips.

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.
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 13.1%.
