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.



The maximum stable clocks of our card are 1075 MHz core (5% overclock) and 1800 MHz memory (20% overclock).

MSI's card reaches the lowest maximum GPU clock, but ends up delivering the highest performance. Memory OC works better than on any other card which is probably due to the cooled memory chips. I am not 100% sure what causes this performance advantage that we also see in our non-overclocked benchmarks. My best guess is that MSI added some secret sauce to their BIOS, by, for example, increasing the power limit of the card, which means that the card will boost higher for longer, while other cards run into the power limiter.

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, determined
during TPU review.


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 12.9%.
