    How to enable A6-1450 turbo mode in linux

    digipoem

      In Ubuntu Server 16.04  A6-1450 can run at 1.0GHz.

      How to enable Turbo mode to run in 1.4GHz?

          Turbo is automatic, controlled by the CPU and BIOS, based on load level and temperatures.

              By command 'cat /proc/cpuinfo', I never saw the cpu working at 1.4GHz.

              Is there any way to force the cpu to work at 1.4GHz?

                By commmand cpufreq-info there is no 1.4GHz.
