![]() Note also that adjusting various minimums would not have any effect on performance mode. In performance mode, with HWP enabled, you should not be able to detect any performance degradation. ![]() The processor can back off the CPU frequencies by itself, even in performance mode. I also tried pstate-frequency: sudo pstate-frequency -S -p maxīut this again only changes scaling_min_freq and the output of cpufreq-info remains ambiguous analyzing CPU 11:Ĭurrent policy: frequency should be within 4.55 GHz and 4.60 GHz.Īpart from using legacy cpufreq_userspace driver instead of intel_pstate, is there any way to set higher minimum (or better constant) CPU frequency? 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. ![]() Frequency still ranges within 800 MHz and 4.60 GHz.Įxample output of cpufreq-info is: analyzing CPU 11:ĬPUs which run at the same hardware frequency: 11ĬPUs which need to have their frequency coordinated by software: 11Īvailable cpufreq governors: performance, powersaveĬurrent policy: frequency should be within 800 MHz and 4.60 GHz. Setting sudo cpupower frequency-set -min 4500HzĪs suggested here does not work. The CPU is Intel(R) Core(TM) i7-8700, with the hardware limits 800 MHz - 4.60 GHz. I want to set higher CPU frequency on Ubuntu 20.04 based system (KDE neon) with 5.4.0-58-generic kernel.
