How to enable A6-1450 turbo mode in linux

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

How to enable Turbo mode to run in 1.4GHz?

Re: How to enable A6-1450 turbo mode in linux

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

Re: How to enable A6-1450 turbo mode in linux

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.
