Rovclock is a utility to control frequency rates of your Radeon card.

For laptop use, this is very helpfull to underclock the Radeon card for powersaving when running on batteries. By underclocking it is possible to prevent the fan from running.

This can also be used to gain performance by overclocking.

Get it from: http://www.hasw.net/linux/
