OverclockingOverclocking results listed in this section are achieved with the default fan and voltage settings as defined in the VGA BIOS. We choose this approach as it is the most realistic scenario for most users.
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 are the highest observed boost clock after overclocking. For this review I've applied the same clock increase to all clock levels.
Maximum overclock of our sample is +453 MHz to the GPU's base clock, which increases max Boost from 1898 MHz to 2114 MHz (11% overclock), and 1450 MHz on the memory (16% overclock).
These are very good results, but the GTX 1080 seems to be limited by the board's power limit and temperatures going above 83°C, which will both result in lower clocks due to NVIDIA Boost. Still, the real-life performance gains are there and are significant - take a look below.
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 12.8%.
