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.
Maximum overclock on our card is 1020 MHz GPU clock (13% overclocking) and 1800 MHz memory (9% overclock).
Overclocking works well and ends up being slightly higher than the GTX Titans we reviewed earlier. This supports my theory that ZOTAC is cherry-picking "good" Titans with high OC potential and low heat output.
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 11.8%.
