OverclockingThe 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)
|Maximum Overclock Comparison|
|Max. GPU Clock||Max. Memory Clock|
|ASUS GTX 670 DirectCU II||1110 MHz||1890 MHz|
|NVIDIA GTX 670||1100 MHz||1760 MHz|
|Palit GTX 670 JetStream||1120 MHz||1750 MHz|
|ZOTAC GTX 670 AMP!||1150 MHz||1890 MHz|
|NVIDIA GTX 680||1147 MHz||1833 MHz|
|ASUS GTX 680 DirectCU II||1207 MHz||1766 MHz|
|AMD HD 7970||1075 MHz||1715 MHz|
will overclock slightly differently based on random production variances.

Overclocked PerformanceUsing 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%.
