Changing CPU Scaling Governor on Linux

Modern processors are capable of operating at a variety of frequencies (or "clock speeds") to balance being able to perform work quickly when required with being energy efficient while the system is idle. Performance issues may arise if the CPU remains at a low clock speed while demanding applications such as games are running.


Favoring Performance

Use the following terminal command to load the performance governor;

cpupower frequency-set -g performance

Note: We recommend monitoring your CPU temperatures while the performance governor is in use. This is designed to cause your CPU to do more work, which places a greater strain on your cooling solution. This can potentially result in overheating.


Returning to Defaults

For AMD CPUs, use the following terminal command to switch back;

cpupower frequency-set -g ondemand


For most Intel CPUs, use the following terminal command to switch back;

cpupower frequency-set -g powersave


Note: Intel CPUs released before 2011 should use the same command as those with AMD CPUs.
