Я всегда замечал, что после разгона на компе выдавалась неверная частота, но тут что то совсем странное. Некоторое время назад вывод был такой (все что ниже относится к ноутбуку Samsung NP355V4C)

maximum transition latency: 4.0 us.
hardware limits: 1.40 GHz - 2.30 GHz
available frequency steps: 2.30 GHz, 2.00 GHz, 1.80 GHz, 1.60 GHz, 1.40 GHz
available cpufreq governors: userspace, ondemand, performance
current policy: frequency should be within 1.40 GHz and 2.30 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.40 GHz (asserted by call to hardware).

P.S. Нашел в логе ядра 3.8 x86,AMD: Power driver support for AMD's family 16h processors т.е. мне выходит наверное остается только ждать. Судя по википедии 16h это вроде как тринити, которая вышла после бульдозера.
