Overclocking
Overclocking is complicated by the fact that the GPU will sit in its power limit all the time, which causes Boost to limit the maximum frequencies. For overclocking this means that Boost can interfere at any time if it senses a high power draw by reducing clocks beyond the targets you dialed in manually.
With manual overclocking, maximum overclock of our sample is 2045 MHz on the memory (17% overclock) and +150 MHz to the GPU's base clock, which increases average GPU clock from 1879 MHz to 1964 MHz (5% overclock).
Testing notes & interpretation- 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.
- Each GPU (including each GPU of the same make and model) will overclock slightly differently based on random production variances.
- The data in this table shows comparable overclocks, using identical conditions, from previous TechPowerUp Reviews.
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 8.4%.
