Samsung Galaxy S II dual-core overclock destroys benchmarks at 1.5 Ghz [video]

It looks like that shiny new and what I'd call extremely thin powerhouse of an android phone you just bought is ready to have some fun. Yes I'm talking about that dual-core Samsung Galaxy S II we have heard plenty about recently. Some of those fancy developers at XDA we are always talking about in the android community have done it again, and already overclocked the SGS II to 1.5 Ghz and that is just the start.

The Galaxy S II is one powerful phone, when we heard it would ship at 1.2 Ghz instead of 1.0 Ghz we knew that was a good sign, but things are looking like 1.5 Ghz and higher will soon be easy to come by, plus the source code has been released so things should start moving along great for dev's and hackers. Thanks to coolbho3000 at xda he's already overclocked it to 1.5 Ghz as a starting point, completely stable and is getting over 4000 in quadrant all day long. Stock SGS II gets around 3500.

What would news about an exciting overclock and speeds like this be without a proper guide to do this yourself, well we have you covered here and with the source if you have any questions. Obviously this is one of those "at your own risk" type deals, whenever I flash something like a kernel I make sure to have a nandroid backup first just to be safe and recommend you do the following, but you probably knew that. Check out the video and details below:

Instructions:
1. You'll need the latest version of odin3 and the USB drivers for Windows. jutley's post on debranding the phone has links to both: Click Here
2. Grab the kernel. It is a tar file for odin with the overclocked kernel and a initramfs with proper modules for the kernel: Click Here
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.

Enjoy it!

coolbho3000 has mentioned he's booted at a blaaazing 2.0 Ghz but unstable and that is a work in progress, and his 1.8 Ghz Linpack score is in the top 10. So be patient, and give him time to iron out all the kinks and soon you can be speeding along much faster also. I did want to mention that it is a shame to see that Samsung chose not to use the EXT4 filesystem like they did here on the SGSII on the new Galaxy Tab 10.1. Obviously they are different CPU's but the I/O scores on the Tab were consistently around 1000 vs 4200. That's a 4x improvement on the Galaxy S 2!

    That’s crazy fast for a smartphone. Can’t wait till we see quad cores in phones. Then we can power a “computer setup” and just have one device for all needs.

      @3eb5fe36f413a26be99cccec41fac0fa:disqus yea quad cores are coming soon, and the Atrix will look like a toy, but for now things are still looking pretty powerful especially if they get the SGSII running at 2.0 Ghz. That is more powerful than most older laptops. lol

    BUT QUADRANTS MEAN NOTHING WAHHHHWWHWHHWHWHWWWHWHW.

    But seriously….that’s pretty damn impressive. +1

    I’ve done this and want more!!! Seeing it SMASH everything including the Xoom is pretty damn impressive. The SGS2 is the best consumer device ever made and has greatly exceeded its much deserved hype. *hats off to Samsung!!*

    Just imagine the SGS3… No doubt quadcore craziness that will put the SGS2 to as much shame as it does the SGS (which is only a year old)!!
