Есть процессор Xeon 2.4.GHz. Включаю управление cpufreq (пробовал в двух режимах ondemand и performance), после загрузки modprobe p4_clockmod максимальная частота процессора 1.6 GHz. Как мне получить заявленные 2.4 GHz?

Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
driver: p4-clockmod
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 0.00 ms.
hardware limits: 200 MHz - 1.60 GHz
available frequency steps: 200 MHz, 400 MHz, 600 MHz, 800 MHz, 1.00 GHz, 1.20 GHz, 1.40 GHz, 1.60 GHz
available cpufreq governors: ondemand, performance, userspace
current policy: frequency should be within 200 MHz and 1.60 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz (asserted by call to hardware).
