It seems that scaling_min_freq is only used for printing information and does not really change performance governor. The governor "performance" may decide which speed to useĬhanging scaling_min_freq does not help either: MAX_CPU=$((`nproc -all` - 1))Įcho 4500000 | sudo tee /sys/devices/system/cpu/cpu$i/cpufreq/scaling_min_freqĮxample output of cpufreq-info analyzing CPU 11:Ĭurrent policy: frequency should be within 4.50 GHz and 4.60 GHz.Įven though frequency should be within 4.50 GHz and 4.60 GHz, current CPU frequency stays 4.23 GHz.

I want to set higher CPU frequency on Ubuntu 20.04 based system (KDE neon) with 5.4.0-58-generic kernel.
