Что я пытался сделать:
[console]
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
2401000 2400000 2300000 2200000 2000000 1900000 1700000 1600000 1500000 1400000 1300000 1200000 1100000 900000 800000 768000

$ cpufreq-set --max 2401000
$ echo 2401000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
[/console]
Но все равно в выводе cpufreq-info такие строчки
[console]
current policy: frequency should be within 768 MHz and 1.70 GHz.
[/console]
и в файле /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq значение 1700000.

Как поставить максимальную частоту?

Конечно не получится, у вас выбран governor ondemand для управления частотой процессора.

                  The governor "ondemand" may decide which speed to use
                  within this range.

Либо выберите governor userspace, что бы управлять частотой процессора посредством cpufreq, либо выберите сразу performance, который выставит частоту процессора на максимум.

Вот доступные governor в ядре вашего дистрибутива.

available cpufreq governors: conservative, ondemand, userspace, powersave, performance

Ну и строго говоря governor ondemand оптималный выбор для ноутбука, на котором хочется большей отзывчивости, частота процессора в случае необходимости, в зависимости от загрузки, будет быстрее повышаться до максимального значения, а когда ресурсоёмкая задача будет завершена более быстрее будет понижаться до меньшего значения в целях экономии батареи и снижения уровня шума.

Так что вы уж определитесь так ли вам нужна постоянно максимальная частота процессора.

Попробовал, не помогает
[console]
# cpufreq-set -c 0 -g performance
# cpufreq-set -c 1 -g performance
# cpufreq-set -c 2 -g performance
# cpufreq-set -c 3 -g performance

Текущая частота у всех процессоров сменилась на 1.7GHz, но максимальная 2.4GHz.

Может я что-то не так делаю? Или может драйвера надо поставить какие

Ниже 1.7GHz ставится, выше - нет

Нашел ответ в этом топике - http://askubuntu.com/questions/37618/is-turbo-boost-working/. Вся информация о частоте в /proc/cpuinfo и в /sys/device/system/cpu/ ограничена размером обычной частоты процессора. Для просмотра текущей частоты в режиме Turbo Boost надо использовать утилиту turbostat.

Можете посказать в чем заключается решение? У меня такая же проблема. Работат только на заниженной частоте. Вручную нужную частоту никак не удается задать.

23.09.2014 09:34 #393505

Ну я так ничего и не сделал.
У меня процессор с технологией Turbo Boost, в этом случае cpufreq-info не показывает реальную частоту, на которой работает в текущий момент процессор. Также и с информацией из файла /proc/cpuinfo. Я думал почему у меня частота не повышается больше 1.7, на самом деле повышается, просто это не отображается. Для просмотра текущей частоты использовал утилиту turbostat.

Жаль. Это не мой случай.

24.09.2014 06:44 #393620

Кстати, cpufreq-info берет данные из /proc/cpuinfo, потому и частоты в этой утилите и в псевдофайле совпадают.

надпись "asserted by call to hardware" по русски означает: выше головы не прыгнешь. У вас и так установлена максимальная частота, большего данное железо обеспечить программно не может. Можно попробовать покрутить настройки BIOS'а(UEFI), но не более того. У меня вот тоже прыгает туда-сюда, хотя хочется, что-бы встало на максимум(при питании от сети), но увы.

Врет что это максимальная частота.
Возможно драйвер кривой.
