安卓手机cpu超频详细设置教程 安卓怎么设置cpu降频

不用软件超频降频CPU?GPU?

官方正式版没试过,因为我已经刷了心灵的集优版了,心灵的内核已经支持频率调节CPU,但是GPU还没有实现。?

CPU?

CPU频率,go【【微信】】都在这个文件夹下面,/sys/devices/system/cpu/,里面分别包含CPU0CPU1。由于高通双核是异步运行的,因此CPU1暂时不好调节(除非你强行打开),因为如果负荷不高,CPU1是关闭的。/sys/devices/system/cpu/cpu0/cpufreq/【【微信】】?这个文件就是我们通常说的go【【微信】】了,可以选用ondemand,?performance,?powersave等模式。降频的话只要改这个文件/sys/devices/system/cpu/cpu0/cpufreq/【【微信】】,比如1026M(你要输入的数值应该是1026000)。?

好了,比方说你想要ondemand模式,最高频率是1026,就用RE分别打开?/sys/devices/system/cpu/cpu0/cpufreq/【【微信】】,然后输入ondemand退出,RE会提示你保存并自动备份。同样打开/sys/devices/system/cpu/cpu0/cpufreq/【【微信】】,输入1026000退出。?

注意调节频率的时候要看你输入的频率是否支持,查看同文件夹下面的scaling_a【【微信】】pan>?

超频我没试过,因为速度已经够快了。?

GPU?

GPUgo【【微信】】自动是ondemand,因此调频的话只需要改max_gpuclk就行了,也就是最高频率。?

分别修改/sys/class/kgsl/kgsl-2d0/max_gpuclk?(默认200000000,代表200m的频率),/sys/class/kgsl/kgsl-2d1/max_gpuclk(默认200000000),/sys/class/kgsl/kgsl-3d0/max_gpuclk(默认300000000)三个文件,输入你想要的频率。同理先参看scaling_a【【微信】】pan>是否支持你的频率。?

改好后用kernel?tunner查看,就会发现频率已经变了。?

注意重启后就失效了。我自己用了个脚本启动的时候自动修改。?
