Gnome下查看
1) 在Gnome菜单栏的底部面板上点右键 —> 添加到面板 –> CPU频率范围监视器 , 然后gnome面板上就会出现此小工具,并显示当前的频率, 点左键可出现可调节的频率
命令行下查看
1) 安装cpufrequtils
此软件是查看cpu当前频率以及修改频率、选择cpu、选择cpu运行方式的。注意,只支持某些可调节频率的cpu,如intel的笔记本cpu
sudo apt-get install cpufrequtils 或yum install cpufrequtils
2)使用方法
cpufreq-info, cpufreq-selector, cpufreq-set。
a) 查看cpu类型、当前频率、支持频率、运行模式等
[root@codeLife codeLife]# cpufreq-info -m
