Fedora не использует реальную частоту процессора.

Форум — Desktop

Разгонял процессор с 3 ГГц до 3.5, но сегодня выяснил, что fedora похоже не использует максимальную частоту процессора.

Как заставить систему использовать процессор на полную мощность?

AMD Turbo Core

Форум — General

Доброго времени суток. Подскажите пожалуйста как включить Turbo Core в процессоре AMD A8-5557M. Данный процессор спокойно может в 2800 MHz и иногда даже в 3100, но под линуксом его потолок 2100 MHz.

analyzing CPU 0:
driver: acpi-cpufreq
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: 1.40 GHz - 2.10 GHz
available frequency steps: 2.10 GHz, 1.90 GHz, 1.70 GHz, 1.40 GHz
available cpufreq governors: ondemand, performance
current policy: frequency should be within 1.40 GHz and 2.10 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).
boost state support:
Supported: yes
Active: no
Boost States: 3
Total States: 8
Pstate-Pb0: 3100MHz (boost state)
Pstate-Pb1: 2800MHz (boost state)
Pstate-Pb2: 2400MHz (boost state)
Pstate-P0: 2100MHz
Pstate-P1: 1900MHz
Pstate-P2: 1700MHz
Pstate-P3: 1400MHz
Pstate-P4: 900MHz

Частота CPU заблокировалась на 1.8Ghz из 2.3Ghz(+Boots) возможных

Форум — Linux-hardware

В общем имею AMD A10.

    Pstate-P4:  1400MHz
    Pstate-P5:  900MHz
Ни смена governor, ни смена максимальной частоты не помогает. Выше 1.8 не выходит. При этом 
[root@bupyc-notebook bupyc]# cat /sys/module/processor/parameters/ignore_ppc
1
[root@bupyc-notebook bupyc]# cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit
2300000
Все это на арче. Никто не встречался с таким? laptop-mode выключен. Да вот что еще странно: 
[root@bupyc-notebook bupyc]# grep -i 'cpu Mhz' /proc/cpuinfo 
cpu MHz		: 1800.000
cpu MHz		: 1800.000
cpu MHz		: 1800.000
cpu MHz		: 1800.000

Странно работает CPU Throttling

Форум — Linux-hardware

Дорой ночи.

Процессор на ноутбуке при нагрузке сбавляет частоту ниже номинальной, хотя температура 48 и в windows такого не наблюдается. 

$ sudo cpupower frequency-info
analyzing CPU 0:
  driver: acpi-cpufreq

    Active: yes
    Boost States: 3

    Pstate-Pb2: 2500MHz (boost state)
    Pstate-P0:  2100MHz
    Pstate-P1:  1900MHz
    Pstate-P2:  1600MHz
    Pstate-P3:  1300MHz
    Pstate-P4:  1100MHz

В простое: 

cpufreq-aperf 
CPU	Average freq(KHz)	Time in C0	Time in Cx	C0 percentage
000	2394000			00 sec 010 ms	00 sec 989 ms	01
001	2520000			00 sec 012 ms	00 sec 987 ms	01
002	2856000			00 sec 025 ms	00 sec 974 ms	02
003	2499000			00 sec 035 ms	00 sec 964 ms	03

При выполнении stress --cpu 4 сразу же прыгает на: 

CPU	Average freq(KHz)	Time in C0	Time in Cx	C0 percentage
000	1743000			00 sec 987 ms	00 sec 012 ms	98
001	1743000			00 sec 988 ms	00 sec 011 ms	98
002	1743000			00 sec 991 ms	00 sec 008 ms	99
003	1743000			00 sec 995 ms	00 sec 004 ms	99

Температура процессора 48 градусов. В windows такого уменьшения не наблюдается, все ядра при полной загрузке работают на 2100MHz. В целом windows работает шустрее.

В чем может быть проблема?
