Different runtimes on 6970 after reboot - because of Power Tune Technology?

I noticed that my application, running on a 6970, has different runtimes each time I reboot my host.


First I thought I might get the numbers wrongs - but I double checked.


The difference in runtime is about +/-7 percent.


Question: Might this be because of 6970s Power Tune Technology? And can I disable this feature?


Background: It is impossible to profile & tune an application when the hardware operates (randomly?) at different speeds.
