I'm trying to enable Turbo Boost on my server. I'm using an Intel Xeon E5 2630 v3 which should support Turbo Boost up to 3.2Ghz, according to Intel's product page.
The problem is that the processor isn't overclocking, and uses 2.4 GHz as a max frequency. To test if the OS is the problem (I have tested Linux Mint and Debian), I've put the SSD in my computer with an i7 3770 where the Turbo Boost works perfectly fine.
This is the output of the "cpupower" command:
mint@mint ~ $ cpupower frequency-info analyzing CPU 0: driver: pcc-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 hardware limits: 1.20 GHz - 2.40 GHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: frequency should be within 1.20 GHz and 2.40 GHz. The governor "ondemand" may decide which speed to use within this range. current CPU frequency is 1.20 GHz. boost state support: Supported: yes Active: yes
It seems that Turbo Boost is enabled (of course, it is enabled in the BIOS), but it won't overclock even though underclocking is working to save energy. Normally it should display the Turbo Boost clock rate of 3.2 GHz as the max frequency, but it won't do it.
So what is the next step to try to enable Turbo Boost on an Intel Xeon server? Do I've to enable some kernel modules or use another govenor?
