Even though Samsung’s Galaxy S II packs in an impressive 1.2GHz dual-core processor, for some folks that simply isn’t enough oomph. No problem, the most popular Android phone can be easily overclocked to a whooping 1.5 GHz, as shown in the above video by coolbho3000 over at the XDA Developers Forum. Just how fast is 1.5GHz compared to 1.2GHz, you ask.

Well, the Quadrant benchmark shows up to sixty frames per second, which is a rather notable performance jump over the factory 1.2GHz clock frequency setting. The posted notes you will need appropriate Windows USB drivers and the latest version of the odin3 tool to deband the handset. REad on…

From there, in just a few simple steps you can bump up the clock frequency to 1.5GHz. Proceed by downloading the overclocked kernel (a tar file) and reboot the phone into download mode using adb reboot download. Flash the kernel using odin3 by placing the tar file in the PDA section and pressing Start, after which the phone will reboot automatically. Finally, use SuperOneClick to root your phone if you haven’t already, fire up SetCPU and enjoy the 1.504GHz heaven.
