Scripts for controlling Intel CPU frequency
My laptop is a Lenovo T440p with a i7-4900MQ. I run Folding@Home on two of my CPU cores. The CPU constantly overheats, and my fan is always spinning at 4440 RPM. I find the noise annoying. Here is what I have done to alleviate the problem.
Enable or disable Intel Turbo Boost(TM)
#!/bin/bash echo "Intel Turbo Boost(TM) Status:" if [[ $1 == "off" ]]; then echo 1 > /sys/devices/system/cpu/intel_pstate/no_turbo fi if [[ $1 == "on" ]]; then echo 0 > /sys/devices/system/cpu/intel_pstate/no_turbo fi state=$( cat /sys/devices/system/cpu/intel_pstate/no_turbo ) if [[ $state -eq 1 ]]; then echo "Off" else echo "On" fi
Setting maximum CPU frequency
#!/bin/bash if ! [[ -z $@ ]]; then for i in {0..7} ; do echo $@00000 > /sys/devices/system/cpu/cpufreq/policy${i}/scaling_max_freq done fi cpufreq-info | grep "current policy" | head -1 | cut -d ' ' -f 3-
Setting CPU frequency governor
#!/bin/bash if ! [[ -z $@ ]]; then for i in {0..7} ; do cpufreq-set -c $i -g $@ done fi cpufreq-info | grep "The governor" | head -1 | cut -d ' ' -f 19-
