The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.80 GHz (asserted by call to hardware) boost state support: Supported: yes Active: yes 2200 MHz max turbo 4 active cores 2200 MHz max turbo 3 active cores 2500 MHz max turbo 2 active cores 2500 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 5 Available idle states: POLL C1-NHM C1E-NHM C3-NHM C6-NHM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 25335 Duration: 44256698 C1-NHM: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 849453 Duration: 224161655 C1E-NHM: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 896433 Duration: 312921850 C3-NHM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 5626050 Duration: 6051341443 C6-NHM: Flags/Description: MWAIT 0x20 Latency: 200 Usage: 20342598 Duration: 171461740095
