Мать MSI 970A-G46
Камень FX-8350
Разгона нет. Перегрева нет.
Сразу после згарузки cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq возрващает 3600000. Это штатная частота прошлого камня. В итоге частота регулируется но не выходит на 4000 - ограничена ступенькой 3400.

0.69% в стате на 4000 - это видно в самом начале камеь немного работает на такой частоте.
Если сделать sudo service cpufreqd restart частота выставляется на 4000 и уже больше не меняется вниз.
Это частоты реальные. Проверял сравнивая производительность в 7z b.
Удаление cpufreqd не помогло, как я расчитывал. Все ровно тоже самое. Если сделать echo 4000000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq говернеры вроде начинаю переключать частоту вверх:
> sudo turbostat

6 3179 93.41 3403 4003
7 3321 97.68 3400 4000
Но только два ядра и не надолго. Если в меню indicator-cpufreq выбрать 4,00 - это не оказывает желаемого действия. Вывод турбостат выше именно для такого случая. Но если установить в меню частоту отличную от 4000 -
она держится достаточно стабильно:

Откуда такая нелюбовь к макс. частоте и как заставить проц работать на полную катушку, когда надо?

Вроде бы система видит 4000. Почему не обновляет значение в /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq и почему так странно ведет себя после обновлния вручную?
