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

Good work, I would suggest you add a note to have the user play with the phone at least for a day before he saves the profile(you never know if it can fall into endless power cycles). Also for a total noob the more important instruction would be how to uninstall it once he freaks out :)

Re: Bakuur's Over-clocking Guide for new comers
 
well ofcourse and your opinion is very appreciated
am still am going to write anathor guide with pictures on how to uninstall
the guide by titan is awfully hard for noob

Re: Bakuur's Over-clocking Guide for new comers
 
Isn't it required to install the enhanced kernel itself before installing the "Settings" to be able to overclock?

Re: Bakuur's Over-clocking Guide for new comers
 
No,
Quote:

Install "Enhanced Linux kernel for power users (settings)" (section 'system' in application manager).
(This will also install "Enhanced Linux kernel for power users" which is the custom kernel aka titan's kernel)
from jakiman's guide

Re: Bakuur's Over-clocking Guide for new comers
 
you need to note that loading ideal limits your freq to a minimum of 500MHz so you need to use the avoid freq command.
if you need to check that its working run
kernel-config show
after setting your limits

Re: Bakuur's Over-clocking Guide for new comers
 
well its for new comers and it will only get them mixed up
so as you shall see i added a note that if they wish to do such a thing they can follow the other guide
as for the "kernel-config show"
again it will make things complicated
so ill add a picture tutorial on what everything means in it :)
thanks alot your suggestion is well appreciated

Re: Bakuur's Over-clocking Guide for new comers
 
since it is for newcomers, you should make the disclaimers about how this can severely **** things up much bigger and prominent, including the stuff about how even if in one device it works the same numbers can permanently brick other devices

ah, i didn't look at the link :D

but to all newcomers its pretty easy to learn, i'd never used linux or done any programming of any kind and i've learn't loads since march with this device :)

Re: Bakuur's Over-clocking Guide for new comers
 
yes but remmber they wont care about all that
all they want is to reach high speeds and thats it

and im glad you like linux as linux is my passion
