［求助］关于CUP（AMD Sempron 3000+）在linux下有控频的工具吗？

[YelYueer]

我的是笔记本，电池不太经用的，呵呵，所以希望能有降频的工具，省省电吧。。。

有的话能具体说说是什么，怎么用吗？谢谢

从新立德里头搜关键字cpu frequency，估计能找到，我的本子是p4的，在5.10版本的时候我就是这么找的。

[种草得草]

powersaved
powernowd

[YelYueer]

怎么用？

[asias.hj]

powernowd这个守护进程会自动根据cpu的使用率动态的进行频率调节
ps aux|grep powernowd 看看它是否启动了的
vi /etc/init.d/powernowd
把
OPTIONS="-q"
改成
OPTIONS="-q -p 500 "
提高它采样cpu频率的时钟周期

更多的man powernowd

enjoy it!

请问它支持celeron m的cup吗 ？

This is a simple client to the cpufreq driver, and uses the sysfs interface in Linux kernel version
2.6. You need a supported cpu, and a kernel that supports sysfs to run this daemon.

The name is somewhat misleading, as any processor supported by the kernel cpufreq driver will work,
not just processors supporting AMD’s PowerNow! technology. This daemon works best with processors
that support more then 2 frequency steps, like those with AMD’s PowerNow!, and Intel’s Pentium M
family.
