I was just having a look at CPUCool and noticed my AMD Sempron rarely ever reaches 1.8GHz which its supposed to be clocked at. The speed normally varies between 1GHz and 1.4GHz which is quite annoying. I also remember that some AMD chips have some energy saving feature which reduces cpu speed if that helps. If this is normal can someone point this out to me.

EDIT: Fixed by setting power setting to "performance" mode, please keep for future reference unless post already exists

What's the point? It doesn't change the overall performance of the CPU. The CPU will clock as high as it has to by itself. Especially not a good idea if one has a laptop.

Most CPUs and motherboards these days have Power saving features especially laptops but desktops as well. what these do is when your computer is not using the full power of the CPU the computer lowers the clock speed and the power to conserve energy, when the computer needs it it speeds it up again. You can change the minimum/maximum power usage in the power options in the control panel, even set it to run at 100% if you wish.
