Samsung Galaxy S II overclocked to 1.5GHz, video inside

It's one thing to see the Motorola Xoom overclocked from 1GHz to 1.504GHz and a completely different one to see the Samsung Galaxy S II overclocked from 1.2GHZ to 1.504GHz (a 25 percent improvement) at 1375mV. A user who goes by the name of coolbho3000 over at the XDA Developers forums has pulled it off. The overclock translates to a score of 4,062 points in Quadrant and 59.121MFLOPS in Linpack.

The overclocker, if we can call him that, has shared his source code on GitHub and has also outlined the following instructions for anyone else interested in giving it a shot:

1. You'll need the latest version of odin3 and the USB drivers for Windows.
2. Grab the kernel. It is a tar file for odin with the overclocked kernel and a initramfs with proper modules for the kernel.
3. Reboot the phone into download mode using ADB: adb reboot download
4. Flash the kernel using odin3 by placing the tar file in the PDA section and pressing "Start."
5. The phone will reboot automatically.
6. Use SuperOneClick to root your phone if you haven't already. ADB should have root access with this kernel so it'll just work.
7. Grab SetCPU and try 1.504GHz.

If that's not enough for you, he's also posted a video of the overclock in action:

The Galaxy S II runs Android 2.3 (codenamed Gingerbread) and is powered by a dual-core 1.2GHz processor. It is the first handset to offer Samsung's Super AMOLED Plus screen technology (4.27-inch display, 800x480 resolution), and is the company's thinnest phone at 8.49mm, with a weight of just 116g. The device also features an 8MP primary camera with 1080p video capture, and a 2MP camera in the front, as well as integrated NFC support on some versions. It also has BlueTooth 3.0+HS and HSPA+ connectivity.

The device's new Live Panel allows you to aggregate web, social networking, and app content to a single customizable home screen. You'll be able to switch between three adjacent home screens by simply pressing and holding on the screen. The phone will come with four new content and entertainment hubs: music, games, e-reading, and social networking.
