пихнул его в автозагрузку системы, после зарузки сразу смотрю cpufreq-info вижу

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 800 MHz - 1.73 GHz
available frequency steps: 1.73 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
available cpufreq governors: ondemand, performance
current policy: frequency should be within 800 MHz and 1.33 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 1
hardware limits: 800 MHz - 1.73 GHz
available frequency steps: 1.73 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
available cpufreq governors: ondemand, performance
current policy: frequency should be within 800 MHz and 1.33 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
