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.

On NVIDIA cards with boost, the values discussed here are base clock. Boost will further increase clocks.



Maximum overclock on our card is 1215 MHz GPU clock (10% overclocking) and 1620 MHz memory (8% overclock).

GPU clock reaches typical HD 7970 / Tahiti levels that are actually a bit on the high side. Memory, on the other hand, overclocks very poorly due to the Elpida memory chips used. Chips from Samsung or Hynix overclock much better and cap out at around 1800 MHz.

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 8.6%.
