My goal is to force all CPU cores to run at maximum turbo frequency (4 x 3.9 GHz) using CentOS 7. Here is the output of
analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us hardware limits: 1.60 GHz - 3.50 GHz available frequency steps: 3.50 GHz, 3.50 GHz, 3.30 GHz, 3.10 GHz, 2.90 GHz, 2.70 GHz, 2.50 GHz, 2.30 GHz, 2.10 GHz, 1.90 GHz, 1.70 GHz, 1.60 GHz available cpufreq governors: conservative userspace powersave ondemand performance current policy: frequency should be within 1.60 GHz and 3.50 GHz. The governor "performance" may decide which speed to use within this range. current CPU frequency: 3.50 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 3600 MHz max turbo 4 active cores 3700 MHz max turbo 3 active cores 3800 MHz max turbo 2 active cores 3900 MHz max turbo 1 active cores
Turbo boost is working as expected - all 4 cores fully loaded are reaching 3.6 GHz. But it would be nice to have
3900 MHz max turbo 4 active cores or less (at least 4 x 3.7 GHz). How to control it?
Is it possible?
