AMD CPU slowing down clocks when starting emulation

[FIPOLINIO]

So I have decent FPS when playing The Legend of Zelda: Wind Waker, in some areas stable and normal 30 FPS and some others decreasing to 26 or so...but just for curiosity I opened up AMD Overdrive to see my CPU clock speeds when using the emulator and I noted that they were going down a lot from the moment I start to emulate a game.

This are my normal CPU speeds.

And this are when I start emulation.
