Heyy guys, please help.
The scenario is:

I was rendering a 3d model yesterday, I have core i7 870 stock speeds 2.93ghz.

The thing is, when I start rendering, the CPU goes upto 3.2ghz, and when the rendering is about to finish, it comes to 2.3ghz.

Today when I started my pc, the default was 1.36ghz.

Is it a weird thing that my CPU overclocks and underclocks by itself, without even asking me?

Even the temperatures are normal when it drops down to 1.36ghz. (49degC for each core).

Is it supposed to happen naturally, or is there something to worry about?

Thanks for your help..!!

It's supposed to happen, though I don't think that it will overclock when all cores are being used. Look for a setting in whatever software you are using to enable use across all cores.

yeah the turbo boost automatically overclock your cpu. but you can disable that through BIOS. i think if you disable the SpeedStep that will disable the TurboBoost function too. or if not, in BIOS it should look like Intel TurboBoost Tech then disable that.
