The governor "ondemand" may decide which speed to use within this range. current CPU frequency: 2.13 GHz (asserted by call to hardware) boost state support: Supported: no Active: no 1600 MHz max turbo 2 active cores 1600 MHz max turbo 1 active cores idle-info --------- CPUidle driver: intel_idle CPUidle governor: menu analyzing CPU 0: Number of idle states: 4 Available idle states: POLL C1-NHM C1E-NHM C3-NHM POLL: Flags/Description: CPUIDLE CORE POLL IDLE Latency: 0 Usage: 882 Duration: 844537 C1-NHM: Flags/Description: MWAIT 0x00 Latency: 3 Usage: 31239 Duration: 8691021 C1E-NHM: Flags/Description: MWAIT 0x01 Latency: 10 Usage: 25948 Duration: 13105496 C3-NHM: Flags/Description: MWAIT 0x10 Latency: 20 Usage: 770230 Duration: 2830699457
