[SOLVED] Why is my CPU clock flickering from 3600 to 4350Mhz

[ChalkyBones]

I'm sitting idle on a word document and my CPU core clock is jumping up and down from 3600 to 4350. If I use easytune to cap the CPU clock to any other figure it will be consistent, but as soon as I set the figure to 3600 it goes back and forth from 4350. Any reason why? some SS of the cores. thanks.

It's probably just turbo boosting for some reason

Modern CPUs use a dynamic clock speed system to get as much performance as possible, with as little energy use as possible on a per core basis. We like to think that our computers are idle, but there are always quite a few processes running in the background (and foreground) on any computer. Clock frequency moving around is normal. By you capping it you are reducing the performance of the cpu by restricting its ability to turn itself back up when it detects the need to do so.
