1.首先修改启动项

vi /etc/default/grub

找到quiet那个位置,后面加空格,再加intel_pstate=disable

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable"

2.加上参数后保存,并更新grub

update-grub

3.保存完后重启生效

root

4.安装cpufrequtils

apt-get install cpufrequtils

5.配置

vi /etc/init.d/cpufrequtils

找到如下:

ENABLE="true"
GOVERNOR="ondemand"
MAX_SPEED="0"
MIN_SPEED="0"

改成:

ENABLE="true"
GOVERNOR="powersave"
MAX_SPEED="400000"  
MIN_SPEED="400000"
#400000 = 400MHz
#performance ondemand 需要改为powersave

6.保存后,重启服务:

systemctl daemon-reload
/etc/init.d/cpufrequtils restart
