Prerequisites


Intel processor

Installing

sudo apt-get install msr-tools linux-cpupower lm-sensors
OU
sudo apt-get install msr-tools linux-tools-common lm-sensors linux-tools-generic linux-cloud-tools-generic
Configuration

Follow the steps below:

Create directory
Create service file
Create service unit file
Set service

Create directory

sudo mkdir /opt/power-mode && cd $_
Create service file


Create the file and save it in /opt/power-mode/powersave-no-turbo-boost.sh

#!/bin/bash

cpupower frequency-set -g powersave
cpupower frequency-set -r -u 800MHz
wrmsr -a 0x1a0 0x4000850089

Set file permissions

sudo chmod +x /opt/power-mode/powersave-no-turbo-boost.sh
Create service unit file


Create the file and save it in "/opt/power-mode/powersave-no-turbo-boost.service"
