CPU: Reset Speed

Cek Speed

sudo -i
# paste <(cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_min_freq) <(cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq) <(cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_max_freq) | column -s $'\t' -t

Reset

To change the maximum frequency lower (you can't change it higher) use this command to change it from 2200 Mhz to 1700 Mhz:

for x in /sys/devices/system/cpu/*/cpufreq/; do echo 1700000 | sudo tee $x/scaling_max_freq; done

NAME

cpupower frequency-set - A small tool which allows to modify cpufreq settings.

SYNTAX

cpupower [ -c cpu ] frequency-set [options]

DESCRIPTION

cpupower  frequency-set  allows you to modify cpufreq settings without having to type e.g.
"/sys/devices/system/cpu/cpu0/cpufreq/scaling_set_speed" all the time.

OPTIONS

-d --min <FREQ>
     new minimum CPU frequency the governor may select.

-u --max <FREQ>
     new maximum CPU frequency the governor may select.

-g --governor <GOV>
     new cpufreq governor.

-f --freq <FREQ>
     specific frequency to be set. Requires  userspace  governor  to  be  available  and
     loaded.

-r --related
     modify all hardware-related CPUs at the same time
