Force your CPU to run at specific frequency without logout or rebooting the system. Fast and accurate!
Disclaimer: Not all CPU are supported, it's only works with Sandy Bridge or newer.
All you have to do is edit the available modes. Here is some available modes:
- auto: This is technically working without any limitation (default).
- idle: Save the most power and cooling the system, this might slow down your activty or task.
- performance: Use maximum available frequency, choose this one for important purpose only! Nothing bad would happend tho.
- save: This is recommended for Browsing or Streaming online, have a limitation at some point.
scaling_max_freq
For idle mode, you have to set scaling_max_freq as lowest as your CPU can handle, mine was 800MHz.
Add some buffer to make it works fine, for example 800 + 50 = 850Mhz => 850000.
scaling_governor
Choose the right governor scaling method.
See available governors for your CPU:
cat /sys/devices/system/cpu/cpufreq/policy0/scaling_available_governors
The output would be like this (less or more):
