Overclocking

Manual overclocking has gotten slightly stabler than on AMD's first drivers. We still had to raise the power limit to its maximum to see any meaningful overclocking.

With manual overclocking, maximum overclock of our sample is 1860 MHz on the memory (6% overclock) and 1850 MHz on the GPU, which increases average GPU clock from 1738 MHz to 1762 MHz (1% overclock). Both GPU and Memory overclocking are limited by the length of the slider in Wattman—not sure why AMD keeps picking such low overclocking limits.

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 1.0%.
