CentOS 6에서 CPU 주파수 스케일링을 비활성화하는 방법은 무엇입니까?

동일한 OS/커널 구성을 가진 두 개의 동일한 베어메탈 서버가 있지만 두 개의 서로 다른 CPU 주파수에서 실행됩니다. 하나는안정적인하나는 2300MHz이고 다른 하나는 1200MHz에서 2300MHz 사이입니다. 에 있는 정보 sudo cpupower frequency-info는 다음과 같습니다.

첫 번째 서버:

analyzing CPU 0:
  driver: intel_pstate
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 1.20 GHz - 2.50 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 1.20 GHz and 2.50 GHz.
                  The governor "powersave" may decide which speed to use within this range.
  current CPU frequency: 2.30 GHz (asserted by call to hardware)
  boost state support:
    Supported: yes
    Active: yes

power management:

,,, 등 기사에 설명된 여러 가지 방법을 시도했지만 sudo service cpuspeed stop소용이 없었습니다. CPU 주파수 스케일링이 전혀 제어되지 않는 것 같습니다.sudo cpupower frequency-set -g performancesudo cpupower frequency-set -d 2000000최대 부스트 주파수powersave드라이버/주지사가 말하는 동안 또 다른 하나는 1200MHz에서 점프합니다 ( performance이것은 주파수를 2000MHz에서 2500MHz 사이로 제한해야 합니다).

그런데 두 서버 모두 온도 제한이 없습니다.

내 OS는 CentOS release 6.6 (Final), 커널은 입니다 3.10.73. CPU 주파수 스케일링을 어떻게 제어할 수 있나요?
