# cpupower frequency-info

 

analyzing CPU 2:
  driver: amd-pstate-epp
  CPUs which run at the same hardware frequency: 2
  CPUs which need to have their frequency coordinated by software: 2
  maximum transition latency:  Cannot determine or is not supported.
  hardware limits: 405 MHz - 5.17 GHz
  available cpufreq governors: performance powersave
  current policy: frequency should be within 2.99 GHz and 5.17 GHz.
                  The governor "powersave" may decide which speed to use
                  within this range.
  current CPU frequency: Unable to call hardware
  current CPU frequency: 3.89 GHz (asserted by call to kernel)
  boost state support:
    Supported: yes
    Active: yes
    AMD PSTATE Highest Performance: 166. Maximum Frequency: 5.17 GHz.
    AMD PSTATE Nominal Performance: 122. Nominal Frequency: 3.80 GHz.
    AMD PSTATE Lowest Non-linear Performance: 96. Lowest Non-linear Frequency: 2.99 GHz.
    AMD PSTATE Lowest Performance: 13. Lowest Frequency: 545 MHz.

 

以下でモードを変更
