Featuring a 1.2 GHz dual core processor, the Motorola Droid RAZR and its younger brother, the power-packed Droid RAZR Maxx can now be overclocked at higher speeds or can be underclocked to save battery life.  All of this is possible, thanks to an overclock/underclock script developed by developer coryjohn87.

Users will never have to worry with regards to setting the clock speed of the processors as the overlock/underclock script already features several overclocking and underclocking profiles already set at different maximum and minimum frequencies.

Take note that overclocking your device is a dangerous thing to do and can cause serious damage to your phone. Proceed only if you are sure of what you are doing and already experienced modifying Android phones in the past.
