FSB frequency can be changed using “+” and “-“ keys, and in most other cases you can simply select a value from the drop-down list.

In the Advanced section there is a very useful CPU Configuration page where you can check the information about your CPU, reduce the frequency multiplier, adjust some processor technologies.

Power is the next useful section for overclocking fans. You should pay special attention to the Hardware Monitor page over there.

It leads to the list of settings for optional fans and thermal sensors.

It is great to also have detailed information about voltages. The Extreme Tweaker section offers very rich options for voltages adjustment, but far not every one can remember what the default voltages for the chipset bridges are.
