Model name: Intel(R) Xeon(R) CPU E5-2620 v4 @ 2.10GHz
Stepping: 1
CPU MHz: 1200.860
CPU max MHz: 3000.0000
CPU min MHz: 1200.0000
And cpupower info as below
# cpupower frequency-info
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 - 3.00 GHz
available cpufreq governors: performance powersave
current policy: frequency should be within 1.20 GHz and 3.00 GHz.
The governor "powersave" may decide which speed to use
within this range.
current CPU frequency: 1.20 GHz (asserted by call to hardware)
boost state support:
Supported: yes
Active: yes
But curious why cpu MHz always reach to 2.299 as max , never reach to 3.00GHz , even if I do stress like "stress --cpu 32 --timeout 600", My kernel is 3.10.0-862.14.4.el7.x86_64
watch -n.1 'cat /proc/cpuinfo | grep -i mhz'
Thanks
