Bakuur's Over-clocking Guide for new comers

Disclaimer - You are fully responsible for any damage / problems caused by overclocking. Not anyone else.
WARNING: just because your friend did it that doesnt mean you can! your processor is very different than his as you use it in a diffrent way than him!
please if you dont know anything about this read all about overclocking before actully try doing it!!!

This is a very simple way to overclock your N900, for more detailed guide refer to Jakiman's guide
and for an easier guide refer to Extremely easy OCing script

1. install "Enhanced Linux kernel for power users (settings)" it can be found in the app managerhttp://i38.piczo.com/view/4/2/h/q/9/...99_59760_2.png

2. install "rootsh" also can be found in the app managerhttp://i38.piczo.com/view/4/2/h/q/9/...00_40667_2.png

3. after finishing the steps 1 and 2 then simply reboot *shutdown the mobile then booting it"

4.open the terminal from the menuhttp://i38.piczo.com/view/4/2/h/q/9/...01_18223_2.png

5.type in the following:
DO NOT TYPE IN THE ASTERISKS AND THE MEANING OF THEM IS SHOWED BELOW

Code:

sudo gainroot

kernel-config load lv*

kernel-config limits 250** 850***

* lv is one type of a profile you can use LV,ULV,XLV and ideal depending on what works best with your N900
** this is the lowest frequency and you can change it to what suits your phone best
*** this is the highest frequency and you also can change it to what suits your phone best

Which will be like this:

Code:

FREQUENCY   Nokia   LV    ULV   XLV   ideal

0 MHz       30      30    25    30    30

125 MHz     30      30    25    20    30

250 MHz     38      38    25    30    30

500 MHz     48      48    33    33    30

550 MHz    *54*     48    38    38    33

600 MHz     60     *54*   38    38    38

700 MHz             54    45    45    45

750 MHz             54    45    45    45

810 MHz             54    48    48    48

850 MHz             54    48    48    48

900 MHz             54   *54*  *54*  *54*

950 MHz             54    54    54    54

1000 MHz            60    60    60    60

1100 MHz            72    72    72    72

1150 MHz            72    72    72    72

Notes:
-Asterisks indicate the first frequency in the kernel which needs overvoltage.
-the minimum frequency while using ideal configuration is 500Mhz(no need to tamper with that if you want less frequencies you can use the ulv or lv or xlv)
if you really want to tamper with the minimum ideal frequency then follow the jakiman's guide i mentioned above

-Nokia is the default profile and the numbers below are the voltages it uses under the frequencies nearby (eg. at 600Mhz it uses 60)

6.okay so now you successfully overclocked your phone but the next time you reboot the phone will go back to the default frequencies

Note:use the phone for a few days and make sure its working fine before you do the following step

in order to save your frequency you will open the terminal again as shown in step "4"

Code:

 

sudo gainroot

kernel-config load lv

kernel-config limits 250 850

kernel-config save myprofile1

kernel-config default myprofile1

and now you are done =D

to make a desktop widget in order to easily change the frequencies then follow this Link
and to show your frequencies then install Healthcheck
it has many other features and i think every N900 must have it
