Как включить Турбо Ядро AMD для AMD A6 6310 на Linux?

Я использую Lubuntu 15.04, я заметил, что мой процессор (AMD A6 6310) работает на частоте на 1 800 МГц и не больше, в то время как AMD обещал 2,4 ГГц с опцией Turbo Core.

Как включить опцию Turbo Core?

CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 4.0 us.
hardware limits: 1000 MHz - 1.80 GHz
available frequency steps: 1.80 GHz, 1.60 GHz, 1.40 GHz, 1.20 GHz, 1000 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1000 MHz and 1.80 GHz.
              The governor "ondemand" may decide which speed to use
              within this range.
current CPU frequency is 1000 MHz.
