OverclockingThe 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 1160 MHz core (15% overclock) and 1830 MHz memory (18% overclock).
GPU overclocking potential is outstanding and exceeds what we have seen on other GTX 670s we have reviewed previously. Memory overclocking, on the other hand, does not work so well, which is probably due to the lack of any cooling for the memory chips.
|Maximum Overclock Comparison|
|Max. GPU Clock||Max. Memory Clock|
|EVGA GTX 670 Sig 2||1160 MHz||1830 MHz|
|MSI GTX 670 Power Edition||1055 MHz||1820 MHz|
|GIGABYTE GTX 670 OC||1060 MHz||1925 MHz|
|ZOTAC GTX 670 AMP!||1150 MHz||1890 MHz|
|NVIDIA GTX 670||1100 MHz||1760 MHz|
|ASUS GTX 670 DirectCU II||1110 MHz||1890 MHz|
|Palit GTX 670 JetStream||1120 MHz||1750 MHz|
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 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 12.4%.
