With a 1.2GHz dual-core ARM processor there are not many people out there who can question the Samsung Galaxy S II’s processing power, however now we are hearing that you can flash the kernel to get roughly 1.5GHz from each core. At the end of this post you can see how snappy the overclock make’s the handset.
You can find out exactly how to overlclock your Galaxy S II over at XDA developers, to summarize you firstly need the latest version of odin3 and the USB drivers for Windows, then download the kernel, reboot your phone into download mode, Flash the kernel using odin3 and then use SuperOneClick to root your phone, once rooted grab SetCPU and set the core speed to 1.504GHz, if all goes to plan you should now be overclocked. All of the files you need can be found via the link posted earlier in this paragraph.
People are suggesting that anything over 1.504GHz becomes unstable and makes the smartphone run at high temperatures, there is some talk of 2GHz speeds (per core) being reached, however as you can imagine this is really pushing the Galaxy II’s hardware above and beyond its capabilities.
If you want to see the performance increase you should run the Quadrant benchmark test before and after carrying out the overclock, apparently the overclocked kernel will easily deliver over 4000 points in Quadrant.
Please be aware of the risks associated with benchmarking before following XDA’s guide, it could potentially result in your bricking your smartphone so don’t do it unless you really want to.
Did this guide help you overclock your Samsung Galaxy S II? If so, what stable clock speed did you manage to reach?
