Via Epia unterstützt Powersave: kann Frequenz runterregeln. Bei Linux macht das das Longhaul-Modul (Kernelmodul zum CPU-Reglen EPIA). | Via Epia unterstützt Powersave: kann Frequenz runterregeln. Bei Linux macht das das Longhaul-Modul (Kernelmodul zum CPU-Reglen EPIA). | ||

The Epia SP8000E uses a 800MHz Nemiah core CPU. By loading the longhaul module - you can throttle the CPU (Tested with 2.6.11.6). Please note that there are many patches to the cpufrequency control - and many are unstable. If your System locks-Hard - you have a bad implementation :) | The Epia SP8000E uses a 800MHz Nemiah core CPU. By loading the longhaul module - you can throttle the CPU (Tested with 2.6.11.6).
