5.open up a terminal window - Control, Alt,T

6.sudo nano /boot/config.txt

7. scroll down to the very end and insert

over_voltage=4
arm_freq=2000

----- or

over_voltage=6

arm_freq=2147

gpu_freq=750 (or 600)

           -------

You can also overclock the GPU if needed - gpu_freq=600

prees Ctrl - X and save by pressing Y

8. sudo reboot

9. open up a terminal window - Control, Alt,T

10. Type- watch -n1 vcgencmd measure_clock arm 
this will display the current CPU speed in real time.

$ sysbench --num- threads=8 --test=cpu --cpu-max-prime=2000 run

 

if you falese overclocking then press "shift" and reboot.
