CPU MHZ output jumping/bouncing

I am watching the CPU MHZ output in the hardware monitor software from gigabyte bios. Is CPU behavior normal to constantly bounce up and down from say 4400 mhz down to 1000 mhz? The temperature is stable at 50C and am not running anything heavy like a game. Might be a noob question but I just thought that it should keep at a certain range of MHz. I feel its a very large jumping constantly.

That's very normal. Like gilbadon said, it's intel's speedstep. A way to make the cpu more energy efficient and keep temps down, it lowers the multiplier when the cpu isn't under load. There's no point in ramping it up to 100% power when it's barely doing anything or idling. I believe amd uses something similar.
CPU's automatically underclock themselves. Intel uses a speed step technology which inteligently changes it for the load on the system. You can bring the CPU to full frequency by doing very simple tasks. This is normal.
