Hi! > Suggest you try the speedstep_ich module. Although mine is not the same > processor, maybe this [1] thread gives you some more info. I have tried all modules, speedstep_ich, acpi cpufreq, speedstep_centrino and any other I can get my hands on. The only module that loads succesfully is the p4-clockmod, wich works fine switching 8 frequencies 160-1300 MHz. I can send any additional info if needed. Thanks for the reply, Rado
