#How to set a lower CPU frequency when idle?

I want my lowest frequency to try to be 1.2GHz instead of 1.7Ghz so I can save energy. My CPU can be stable at 3.6Ghz but sometimes can go up to 4.7Ghz depending on the task

I honestly don't remember how I did it, cd into /sys/devices/system/cpu/cpu0/cpufreq and try to cat and then echo some values into files like scaling_max_freq, scaling_min_freq

just experiment. It's only one core so you really can't break it

#

maybe use like cpu2 just in case

you might wanna take a look at the wiki for this

#

you can manage CPU power profiles manually or through tools that interface with the governor

#

if you're worried about power consumption, temps, etc. you might also wanna undervolt it

It's like that period of time right before the pc sleeps
