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 1100 MHz core (5% overclock) and 1890 MHz Memory (26% overclock).

Relative overclocking potential of the ASUS DC II is not as big as other cards due to the high out of the box overclock. Overall GPU overclocking works well, yet can not reach the clock levels we have seen from the GTX 680.
Memory overclocking is great though. The card reaches 1890 MHz, which is only 5 MHz below the highest memory clock every recorded at TPU. Compared to the GTX 670 reference design, we see over 100 MHz more memory OC potential.

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,
reached 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 10.6%.
