OverclockingThe overclocks 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, that's why our results here can only serve as a guideline for what you can expect from your card.
Maximum stable clocks of our card are 1225 MHz core (10% overclock) and 1780 MHz Memory (19% overclock).
GPU overclocking works great! The maximum clock of 1225 MHz is higher than on any other GTX 680 we reviewed so far. Memory on the other hand does not overclock so much, other cards easily reach higher clocks, and ZOTAC's AMP edition even gets over 100 MHz more than the MSI GTX 680 Lightning.
|Maximum Overclock Comparison|
|Max. GPU Clock||Max. Memory Clock|
|MSI GTX 680 Lightning||1225 MHz||1780 MHz|
|MSI GTX 680 TwinFrozr III||1147 MHz||1825 MHz|
|ZOTAC GTX 680 AMP!||1130 MHz||1895 MHz|
|Palit GTX 680 JetStream||1165 MHz||1833 MHz|
|ASUS GTX 680 DirectCU II||1207 MHz||1766 MHz|
|NVIDIA GTX 680||1147 MHz||1833 MHz|
|AMD HD 7970||1075 MHz||1715 MHz|
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,

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 13.4%.
