为什么我的cpu不能全速运行?

suse 9.2 pro on IBM laptop R40 AC1 Pentium M 1.3Ghz.
最近用kde infor center 察看cpu,发现只工作在598Mhz下,问各位达人如何让cpu全速运行? 谢谢了先!

那你就编译一次内核就行,make的时候保证他全速运转!! :twisted::twisted:

是不是电池供电模式?接回AC电源试试,有些型号笔记本在电池供电时自动调整CPU频率以进行最大省电

又学到新东西!! :mrgreen::mrgreen:

我已经重新编译过了,选cpu型号的时候选的是pentium M, acpi里面的默认模式也是high performance阿

thanks all of you, i have solved this problem. since in default high performace scheme in SuSE ACPI, the cpu frequency scaling is still active, it means the freq. actallly is dynamic when system ruuning in performance scheme.i have already turned off freq. scalingand cpu is running in its maximum frequency now.

BIOS里边有设置省电模式
把供电设成AC,还有个什么选项就是以最大频率运行的
呵呵,我是这么设的
