Hi, I have just recently built my first gaming pc and I'm a complete noob at this and I really need some help S:

I just downloaded CPU-Z, something my friend suggested for me to use to check my processor and my core speed for my i3-2100 should be 3.10GHZ.

But CPU-Z shows:

Core speed: 1596.4 MHz
Multiplier: x 16.0
Bus Speed: 99.78 MHz

Is there something wrong with my processor? (and I never touched my bios). Please help (:

Intel's SpeedStep automatically downclocks the CPU when there is no load to save power and reduce heat.

You can download a program called Prime95 to stress the CPU. That should increase the clockspeed to 3.1GHz.
