Overclocking

AMD has once again changed the UI for overclocking in Radeon Settings. I feel it has slightly improved. There are a few very minor bugs that will be fixed in no time, I'm sure.

Just like on previous cards, slider lengths limit your overclocking potential. While this is no problem for the GPU clock, memory overclocking basically means "drag the slider to its maximum and be done."

At first I was surprised that I saw no performance gains from overclocking, it seems the power limit is to blame here. Even when overclocked, the power limit will cap the maximum frequencies, so I've set it to the maximum for a second round of OC results.

While there is a voltage adjustment slider in Radeon Settings, it only lets you undervolt the card, which can still be useful.

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 9.1%.
