노트북에서 CPU 주파수를 설정할 수 있습니까(BIOS에서 CPU 설정을 사용할 수 없음)? 이렇게 '부스트 주파수'를 설정하려고 하면 성공하지만 비부스트 상태에서 주파수는 최대 주파수로 설정됩니다. 내가 뭔가 잘못한 게 아닐까?

CPUs which run at the same hardware frequency: Not Available
CPUs which need to have their frequency coordinated by software: Not Available
maximum transition latency: 4.0 us
hardware limits: 1.40 GHz - 2.40 GHz
available frequency steps: 2.40 GHz, 2.00 GHz, 1.70 GHz, 1.40 GHz
available cpufreq governors: userspace ondemand performance
current policy: frequency should be within 1.40 GHz and 2.40 GHz.
The governor "userspace" may decide which speed to use
within this range.
