I'm sorry. I couldn't help it.
Hey, everybody. Look
at the link. Mfusik has an E8500 running at 2 GHz (333 MHz X 6
Mfusik, you have something called SpeedStep enabled in the BIOS. That is the default condition. SS reduces CPU speed when it is under light loads. It will automatically jump to full speed when the CPU workload increases enough.
Most of us use a program called Prime95 to load the CPU cores to 100% of capacity. Do that. Then you will see your CPU speed jump to what you thought you were buying.
You do not need to touch anything.
Later when you get more comfortable with your system and learn a little more, you may want to try your hand at overclocking.

That's when you may need to increase voltage. You will learn how and why there.
