I've been watching my CPU in CPU-Z go from around 800mhz up to what its clocked at (3.08Ghz), is there a way I can stop it from doing this? or is this something normal? I have an Asus M5A78L-M LX board with an AMD Athlon II X2 240 Processor

If you don't mind the extra power usage then reboot and hit delete to enter the bios, then look for an option called cool n quiet and disable it.

For normal usage coon n quiet will not impact your performance but if you are gaming then it can sometimes cause stuttering (depending on the game)

Just curious, but why would you want to do this? It would shorten the life span of your internals and cause extra heat and power consumption when not needed.

Anyways, As Razor said, you can choose that option in the BIOS.

This is normal.

It is to save power and prolong the life of your processor. It is like sleeping a little when you are not doing anything. But open up a program it will awake and increase the clock to make it run fast.

I advise you do NOT go into the BIOS if you don't know what you are doing.

I was just trying to figure why this happens. I'm trying to figure out how to get the best performance out of my system since i do alot of gaming,

When you game Your CPU "awakes" so that it goes to the max Speed and Performance it is put at. If you want you can Overclock your CPU so that when you game it goes to that higher speed which usually has a performance boost if you increase it enough. Though I do not recommend doing this if you do not know what you are doing.

The New BIOS versions are easier to OverClock but still be careful. What game are you trying to get an increase on? Sometimes you are best off overclocking your GPU.

Well, a few games, Boarderlands, L4D 1 & 2, and Black Ops

What GPU are you running?

For those games you don't need a boost in your CPU (depending on your CPU) just a GPU boost or a better card. What CPU and what GPU do you have?

This is normal. It happens to save power and reduce heat.

The best approach is to leave it as it is, the processor will manage itself, they all do these days
