How To Overclock Samsung Galaxy S 2 To 1.5Ghz


samsung-Galaxy-S-2-ocThe Galaxy S II, a powerhouse of an Android phone as it already was, has been pushed to 1.5Ghz! That’s one mean overclock considering the fact that the phone runs a dual-core processor. The overclock is apparently stable and the difference is even visible in everyday usage, not just in benchmarks. More on how to overclock your Galaxy S II after the jump!

The overclock has been made possible thanks to XDA-Developers forum member coolbho3000 who has basically put together an overclocked kernel, that once flashed to your phone, would allow you to overclock the device.

According to the developer, the voltage has been left at a steady 1375mV which is enough for a stable overclock at 1.5Ghz. Now let’s move onto how you can overclock the Galaxy S II.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.



  1. To begin, download the overclock kernel (galaxysii_oc_v1.tar) from the link above.
  2. Make sure your device is disconnected from the computer and then start ODIN.
  3. Click on the PDA button in ODIN and select the file named galaxysii_oc_v1.tar.
  4. Now put your phone in download mode and connect it to your computer.
  5. Make sure to see that Repartition is not checked.
  6. Once all the above steps are completed, simply hit the Start button in ODIN.
  7. Once the process completes – which should not take more then a few seconds – the device will reboot.

That’s it! Download Setcpu from the Android Market and set your desired frequency.
