Overclocking
Overclocking results listed in this section are achieved with the default fan, power, and voltage settings as defined in the VGA BIOS. We choose this approach as it is the most realistic scenario for most users.
Every sample overclocks differently, which is why our results here can only serve as a guideline for what you can expect from your card.
As mentioned on the previous page, the card is TDP limited, even at stock, so we increased the power limit in order to actually reach the dialed in clocks.
Maximum overclock of our sample is 2230 MHz on the memory (12% overclock) and 1430 MHz on the GPU (4% overclock).

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.
Using these clock frequencies, we ran a quick test of Unigine Heaven to evaluate the gains from overclocking.
Actual 3D performance gained from overclocking is 6.2% (some of that is due to the increased power limit to avoid hitting the TDP limit).
