How To Easily Overclock Your Nokia N900 In Under Two Minutes

The ability to overclock the N900 has existed for a long time now and we have covered it before. But overclocking the N900 has never been so easy, two simple installs from the Application Manager and a short command via the terminal is all it takes. If you have been wanting to try it out but were holding out because it seemed too complicated, this guide is for you.

How To Easily Overclock Your N900 In Under Two Minutes

However, please note that overclocking the N900 will void your warranty, although it is possible to the flash to the stock kernel/state if you no longer want to overclock your device. Apart from that you also risk damaging your device and losing data. Please continue at your own peril.

That said, lets get started.

  • The first thing you need to do is install ‘rootsh’ from the Application Manager, make sure you have the relevant repositories enabled.
  • Next install the ‘Enhanced linux kernel for power users‘ from the ‘System’ section in the Application Manager. It supports overclocking upto 1.15 Ghz.
  • Restart the device.
  • Now install ‘Enhanced kernel for power users (settings)‘.
  • Open the X-Terminal and enter the following command.
sudo gainroot
kernel-config load ideal

This will load the ideal profile which overclocks your phone to 850 MHz. At this point if you experience reboots or the phone seems to act funny, try using the ‘lv’ settings that uses slightly higher voltages than the ‘ideal’ profile. If it is still unstable try ‘ulv’. The various presets are ‘default’ – ‘lv’ – ‘ulv’ – ‘xlv’ – ‘ideal’ – ‘starving’.

sudo gainroot
kernel-config load lv
kernel-config limits 250 850

If the N900 seems stable, you can have these settings as a preset of your own.

sudo gainroot
kernel-config load lv
kernel-config limits 250 850
kernel-config save myideal

With the current configuration, the N900 will resort to the default 600 MHz state everytime it is rebooted. This is done to avoid letting the N900 get caught in a reboot loop. If you are happy with the N900’s performance and stability, you can then also set the N900 to overclock by default on startup. Use the following command:

sudo gainroot
kernel-config default ideal (whichever preset you want to set as default e.g. myideal)
kernel-config show (this will show you your current settings)

If you want to revert to the original settings, here is the procedure to follow. Jakiman over at talk.maemo.org has a very comprehensive guide as well, if you are looking for more information I suggest you give it a read.

Overclock N900 With QCPUFreq

One last thing, if you want to configure the N900’s overclocking setting with a visual UI and not the terminal, install QCPUFreq from the Application Manager. Then once you have installed the packages mentioned above all you will need to do is move the slider to overclock to the desired level. My suggestion is don’t go past the 850 MHz mark.

Before you do this, please keep in mind one thing ‘because it can be doesn’t mean, you have to do it!’

The N900 Overclocked To 1GHz

The N900, labeled as a hacker’s phone, comes with a Cortex A8 clocked at 600 MHz. So how long was it going to be before users pushed the limits?  We now have N900’s running at an impressive 1GHz or 900 MHz or 800 MHz, you can basically pick the speed you want.

Before you entertain thoughts of doing this to your N900, do keep in mind that overclocking is generally known to reduce the life of your processor and cause stability issues, not to mention the battery drain. Manufacturers generally clock the processors to a slightly lower level than what can be safely reached, but 1 GHz sure seems to be pushing it.

That being said, reports suggest that the N900 is even more snappy at 800 MHz, up from the 600 MHz that it originally comes with. Such a hack would be useful in high duty tasks like video playback or capture.
