How To Enable Control Power Saving Mode for AMD Processors

Is your desktop being powered by Fedora? Does AMD Athlon/Duron processors powers your system?

Here's a quick tip on how to have management and control over your AMD Athlon/Duron powered processors using Fedora 9.

Athcool is a small utility, enabling/disabling Powersaving mode for AMD Athlon/Duron processors.  By installing Athcool into you desktop, you can benefit more of the following issues

• save power consumption


• lower CPU temprature when CPU is idle.

Powersaving works if your kernel support ACPI (APM not work), because athcool only set/unset "Disconnect enable when STPGNT detected" bits in the Northbridge of Chipset. To really save power, someone has to send the STPGNT signal when idle. This is done by the ACPI subsystem under C2 state.

!!!WARNING!!! Depending on your motherboard and/or hardware components, enabling powersaving mode may cause

• noisy or distorted sound playback


• slowdown in harddisk performance


• system locks or instability


• massive filesystem corruption (rare, but observed at least once)

If you met those problems, you should not use athcool. Please use athcool AT YOUR OWN RISK. You've been warned.
