Overclocking

Manual overclocking has gotten a little bit more stable than on AMD's first drivers. We still had to raise the power limit to maximum to see any meaningful overclocking.

With manual overclocking, maximum overclock of our sample is 1900 MHz on the memory (9% overclock) and 2100 MHz on the GPU, which increases average GPU clock from 1961 MHz to 2050 MHz (5% overclock). Memory overclocking is limited by the length of the slider in Wattman, which goes no higher than 950 MHz.

Overclocked Performance

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 3.9%.
