Dell XPS 15 (L521x)

  I recently noticed that the build on my Dell XPS has a 3rd Generation Intel® Core™ i7-3632QM CPU @ 2.20GHz (7200RPM), but Dell is offering 3rd Generation Intel® Core™ i7-3632QM processor (6M Cache, up to3.2 GH)

Is there anyway now that I can get my intel core to run at 3.2 GHz?   I really do desire the extra speed.  Anyone have any suggestion on how I  can accomplish this.

Thanks
