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.

I am not aware of power tune technology.Although i suggest you to ask this question in a more relevent category.

Regarding your differnet runtimes its better to post some code or send a optimal test case to streamdeveloper@amd.com
