Overclocking

The 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 1185 MHz core (13% overclock) and 1635 MHz Memory (9% overclock).

GPU overclocking potential is good and seems to be higher than other "standard" HD 7970 cards. Only the MSI HD 7970 Lighting gets similar clocks, which might be because MSI is picking from the best GPUs, too.
Memory overclocking does not work so well, which is surprising as other cards using the same board design and memory chips get higher clocks here.

Important: Each GPU (including each GPU of the same make and model)
will overclock slightly differently based on random production variances.

Overclocked Performance

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 13.7%.
