    Increase bios limit of cpufreq


      Hi all,


      I have a Xeon E5-2697 v4 CPU, which is posted to have a max cpu freqency of 3.6GHz, which I cant seem to reach. I've fiddled with the bios options, plugged in the backup power supply, and done everything I can, but I cant get it to step over the 2.3Ghz mark.


      my OS says that the:

      cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

      2301000 2300000 2200000 2100000 2000000 1900000 1800000 1700000 1600000 1500000 1400000 1300000 1200000


      And the bios_limit is:

      cat /sys/devices/system/cpu/cpu0/cpufreq/bios_limit



      Which Bios options do I need to set to enable 3.6Ghz?
