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 1095 MHz core (10% overclock) and 1670 MHz Memory (48% overclock).

GPU overclocking potential is on the lower end of the clock ranges we have seen from other HD 7770 card, but close enough to not make any significant difference as long as reference designs are considered. Custom designs like the ASUS HD 7770 DC II offer a bit more here, but at higher cost.

Memory overclocking is outstanding and better than any HD 7770 we tested so far.

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 Call of Duty 4 to evaluate the gains from overclocking.


Actual 3D performance gained from overclocking is 11.1%.
