CPUfreqUI is a graphical userspace application for Nokia N900 with which we can adjust the CPU frequency of our N900. You can use both if we have done overcloking as if you do not.

If we have not done overcloking, only we can adjust the frequencies available: 600MHz, 550MHz, 500MHz and 250MHz. If we have done overcloking, then we will have more frequencies to adjust.
Interesting application, with which we can save a lot battery, in addition to use our overcloking to the maximum when interest us. Its use is very simple, in the Governor tab we have two options: “ondemand”, for which the processor use the frequency you need in each time, and “userspace”, to operate in the frequency that we have chosen. If mark smart reflex force to saving the battery.
In the tab status can view the current temperature of our processor.
