How to overclock the Nokia N900?

Posted: 25 Mar 2011 08:22 PM PDT

Hi guys, today I’m gonna show you how to overclock your N900 to make it faster to run more applications at once without much lag. Overclocking is the process where you run your processor at a higher clock speed than the default set by the manufacturers.

Before getting started, you should have these two packages installed onto your phone

Kernel-power-flasher and Enhanced Linux kernel for power users (settings)

To install the above packages, go to X-Terminal and type the following

  • sudo gainroot
  • apt-get install –reinstall -y kernel-power kernel-power-flasher

After installing these 2 packages, restart your phone and go to X-Terminal and type this in sequence

  1. sudo gainroot
  2. uname -r

You should be prompted with a message such as this ” 2.6.28.10power46″

This means that you’re on the right track to overclocking your phone

Next type ” kernel-config show” and you will be prompted with something like this

So for example if you want to try the lv profile  (lower voltage than default) and also min and max frequency of 250 and 850, you type the following
  • kernel-config load lv
  • kernel-config limits 250 850

This configuration is reset to default factory settings if not saved upon reboot

If you do want to set an overclock profile to auto-load upon boot up, use the following command:

  • kernel-config load lv
  • kernel-config limits 250 850
  • kernel-config save myprofile
  • kernel-config defaults myprofile

Then you have just successfully overclocked your N900.

Important things to take note:

There are several profile name you can’t save as, so that you don’t replace any of the provided set of configurations given by kernel-config

These profiles are lv, ulv , xlv and ideal

And for the available frequencies available for use is listed down under “supported frequencies” when you type kernel-config show. Frequency above 1000Mhz is considered unstable.

For voltage comparison DEFAULT > LV > ULV >XLV >IDEAL

After all this I’m sure you guys can play around with different clock speed after overclocking your N900 using kernel-config. This also releases the full potential of the ARM A8 in your device

Installing Preenv on N900 to play webOS games on the device

Posted: 25 Mar 2011 02:28 AM PDT
Dear nokia N900 website readers, My name is Pang Zi Yang and I am the co-writter here with Maciej. I hope you like my articles. I’d like to start showing you how to install Preenv on N900 so that you can be able to play webOS games easily.
Those of you might get this error when trying to install preenv using the .deb file
“Incompatible application package”
Some may not find Preenv in the App Manager
—It isn’t there—
So to install Preenv is actually very simple.
You will need to activate extras , extras-testing and extras-devel repository in Application Manager
Go to Xterminal and type this in sequence
  • root
  • apt-get install libgles1-sgx-img
  • apt-get install preenv
  • apt-get install libsdl-net1.2

    • This would get your Preenv up and running.

    Next is to install your webOS game onto your N900.

    METHOD 1

    • First download the *.ipk file
    • unpack the *.ipk file using e.g. 7zip and extract the /applications/ folder from it
    • put the extracted /applications/ folder to /home/user/ on the N900 using SSH
    • Go to X-Terminal and type the following in sequence
    1. sudo gainroot
    2. cd /home/user/applications/ folder
    3. chmod +rwx filename
    4. To run the game, simply type ./filename in X-Terminal (where filename is the name of the executable file. eg. nfsuc in the case of Need For Speed Undercover)

    Need For Speed Nokia N900

    METHOD 2

    Download the .deb file and install it through Hildon Application Manager.

    You can find on the web where people have repacked the .ipk files into .deb files.

    This method is much easier and faster for beginners
