Overclock a Samsung Galaxy Tab 2 (7.0) to 1.3 GHz

The Samsung Galaxy Tab 2 (7.0) is an inexpensive 7 inch tablet with a decent screen, a relatively zippy 1 GHz dual core processor, and Android 4.0 operating system.

But if you want to get even more performance out of this $249 tablet and don’t mind voiding your warranty (and possibly breaking something in the process), there’s a way to do that.

Samsung Galaxy Tab 2 (7.0)

Now that it’s possible to root the 7 inch tablet, install ClockworkMod Recovery, and even load custom ROMs, hackers have also started playing with custom kernels.

Android developer Metallice has released a kernel for the Samsung Galaxy Tab 2 (7.0) which allows users to overclock and underclock the tablet’s processor and even the graphics processor.

Normally the TI OMAP 4430 chip has a top speed of 1 GHz, and the graphics core runs at 307 MHz. The Metallice kernel lets the CPU run at speeds up to 1350 MHz and the GPU can be overclocked to 448 MHz.

The chip can also run as low as 150 MHz to save energy when you don’t need all that extra performance.

You can install the custom kernel by first installing ClockworkMod Recovery and then using the “install zip from sdcard” option to load the kernel. Download links for the latest versions of the kernel are available at RootzWiki.

Keep in mind, this is not officially supported by Samsung and you will almost certainly void your warranty. So if you damage your device don’t expect anyone to fix or replace it for you.

    1st – Does this have Gorilla Glass?   Is it easy to replace battery so can have second batter on hand due to Overclock using more power?

    2nd – The ultimate mod of the Galaxy Tab II 7 inch… is spelled out below, this would be my dream.  Is this possible to do?

    How do you root this and put Lubuntu on it, not just a VM operating version using remote access to do it.  (Dual booting between Android and Lubuntu, with both operating system file storage separated and fully encrypted using TrueCrypt).
    How would you add a 7 inch Pixel Qi Screen to this… at this price and with the processor Overclocked, if you could have the processor shut off (like Mary Lou states you can with LINUX), so that it only turns on when needed, you save battery, and the Pixel Qi Screen would be longer batter life too (with out doors direct sunlight use)I would love to have better than 1024×600 screen!  With Linux, you can scale the resolution to 1280×768 (or so).  If this were done, then can you use Xrandr command to scale and use – see:

    https://bbs.archlinux.org/viewtopic.php?id=118999

    Command like this (but read whole link above).
    xrandr –output LVDS1 –scale 1.25×1.25

    (note I have done this with netbooks that have 1024×600 screen, and it works, looks great… only have the problem described in the above url.
    So, if this were done, then would all the “touch screen then work with this” ? My bet is that it would.  The patch does work.  But, why don’t the LINUX folks fix it so the scaling works out of the box, then you could use Arandr with some scripting to change resolution on the fly!

    Conclusion – you would have fully encrypted dual boot Lubuntu/Android device, with daytime direct sunlight screen, long battery life, and 1280×750 resolution.  

    So,  how is this done, is anyone doing it?  If so, where is the how-to?

       Gorilla Glass, yes… Pretty much standard these days.  Though mind that Gorilla Glass is still Glass and it ranges from scratch resistant to shatter resistance.  So just having it doesn’t mean it’s necessarily all that durable.

      Batteries though are sealed in the Samsung design and they’re not really intended for consumers to take apart.  Maybe a iFixit tear down will show how later but generally assume you’ll be stuck with the default.

      For Root…

      However, getting Lubuntu running on it may be harder until developers have had time to play with the device and release a compatible version.

      It’ll be easier getting custom ROMs of Android till then…
