i5 keeps changing clock speeds every 5secs

When watching a video in VLC media player I notice that CPU-Z reports the clock speed alternating between 1.2Ghz to 2.6ghz every 5 seconds, I've got CPU stepping enabled in the BIOS of my Asus P7P55DD mobo but surly this should only kick in when playing games and doing intensive things, not for a video right? (it is 720p though).

Why is it constantly flipping between 1.2 and 2.6ghz though? Surly this isnt healthy for the CPU, is there a way I can make it so the stepping only works for when Im playing games?
 
It's not unhealthy for the CPU :) To be fair I was a bit suprised when I first saw my core 2 doing this a few years ago too.
 
Hopefully in the future we'll see an even greater range of processor throttling to save power and noise. It'd be good if the processor could decide it would be most efficient, for instance when watching a movie, to power cores 1 and 2 to exactly 1500mhz and power cores 3 and 4 down. And so on and so forth.

But I don't think it takes the processor much "effort" to downclock. Doesn't it have dedicated hardware to do this for it?
 
Wouldn't worry about it.

CPU-Z likes to report, validate and even make up the clock speed to go along with the rumour that my i5 750 is using a 24x multiplier.

Strange things happen when power saving is enabled.
