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 1115 MHz core (8% overclock) and 1750 MHz memory (17% overclock).
While the MSI card reaches lower clocks than other GTX 660s tested today, the resulting performance is better. We have seen the same behavior in our GTX 660 Ti reviews and suspect that MSI found a way to get more performance than other board partners out of their cards.

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 15.5%.
