coolrun 1.1

coolrun is a small shell script which enables or disables the power saving features on AMD Duron/Athlon/Athlon XP processors.
coolrun is a small shell script which enables or disables the power saving features on AMD Duron/Athlon/Athlon XP and some Sempron processors using direct hardware access to the Northbridge chipset. The project requires the 'setpci' utility from the pciutils package.

At the moment, a lot of chipset models are supported with the exception of the ATi and ALi chipsets because of missing public info.

Main project site of the script is at SourceForge - http://sourceforge.net/projects/coolrun

NOTE: if you experience some strange behaviors after enabling the power saving features on your chipset like system lock-ups, instability, decreased disk or USB performances, then this is not the script's fault! This is a chipset issue and cannot be "fixed" by this script. The settings this script uses work perfect on some systems but on others they lead to strange behaviors, most notably on systems that use early versions of the VIA KT133/KT266 chipsets. However, if you do notice strange behaviors, then just deactivate the setting using the '-d' option or in rare cases just reboot your system. Some BIOSes provide settings that can further improve the stability/responsness of your system while the powersaving settings are enabled.

I'm not responsible for any damages to your system when using this script. Different motherboard manufacturers use the same chipsets but with different voltage lines and/or capacitors, thus one system can behave very normal while others experience random lock-ups or performance issues. However, I've tested the script on a wide range of chipsets and so far I'm pretty pleased with its operation, though I'm always looking to improve it :)


How to test if the settings work?

After enabling the powersaving features on your chipset, you can use a monitoring program like GKrellM to check out the temperature on your processor. Also you can check out the CPU fan speed to see if the fan's rotation slows down which means that the system is decreasing its speed because the CPU is running cooler and there's no need for the fan to operate at a high speed.
