For the benefit of anyone else reading, Overclocking a RPi is a very easy procedure.
You either need to edit the config.txt file which is stored on one of the partitions on the SD card or use a built in Overclocking app like the excellent one in the new OSMC OS. There is also a Kodi add-on I believe available.
Config.txt file, example on standard Turbo settings:
(and for those being extreme cheapskates and thinking of trying my Licence codes on their RPi2. They actually wont work as they are tied to individual RPi's)
