Por padrão, sua CPU deve ser executada no regulador "ondemand", o que significa que, quando precisar, será ampliada.
Se você quiser que suas CPUs sejam executadas a 1.86Ghz o tempo todo, execute cpufreq-selector -c 0 -g performance
e cpufreq-selector -c 1 -g performance
.
Se você usar cpufreq-info
, poderá verificar se o administrador está funcionando corretamente:
$ cpufreq-info

[…snip…]
hardware limits: 800 MHz - 2.10 GHz
available frequency steps: 2.10 GHz, 2.10 GHz, 1.60 GHz, 1.20 GHz, 800 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 800 MHz and 2.10 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 2.10 GHz.
