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 ** 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: http://i38.piczo.com/view/4/2/h/q/9/...02_63990_2.png http://i38.piczo.com/view/4/2/h/q/9/...03_16532_2.png http://i38.piczo.com/view/4/2/h/q/9/...10_49217_2.png http://i38.piczo.com/view/4/2/h/q/9/...11_88874_2.png http://i38.piczo.com/view/4/2/h/q/9/...12_99803_2.png http://i38.piczo.com/view/4/2/h/q/9/...13_13571_2.png Code:
FREQUENCY Nokia LV ULV XLV ideal -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:
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 |
Re: Bakuur's Over-clocking Guide for new comers
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,

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

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 |

don't want to nitpick, but could you remove the stars *** from the command lines one has to type in? If i'd be a real noob, i'd type the stars in mercilessly, too.
|
Re: Bakuur's Over-clocking Guide for new comers
thats why i added the pictures
if you see they show you exactly what to type and the exact outcome its just that i was looking for a way to show that its an example if you have a better idea to show so please mention it |
Re: Bakuur's Over-clocking Guide for new comers
I would not encourage anyone to set a default kernel-config. It is far safer IMHO to allow the n900 to boot with the default frequency and use a startup script to OC it. I use a Queen Beecon command that runs on the startup of the desktop.
If you set the default to an unstable frequency, you can end up in an endless reboot loop and have to reflash. |
Re: Bakuur's Over-clocking Guide for new comers
Totally agree with cfh11. I know there's a recommendation to test a profile for a while before saving it as default, but IHMO it's bad practice for anyone to ever set a non-stock OC and/or LV profile to load at boot.
|
Re: Bakuur's Over-clocking Guide for new comers
i use the ulv 850mhz profile at boot up
remmber that the only reason you would set an overclocked profile as default is to get a faster boot up and i need that as i reboot alot |

Re: Bakuur's Over-clocking Guide for new comers
One thing you should keep in mind that the overclock settings also influence the DSP. I found out this can have great impact on using the camera/video applications.
I used used o overclock at 850 MHz using the ulv settings. But after a while i noticed strange things happening when taking pictures or video. I went back to only 700 Mhz with higher voltages. The camera/video problems are gone now. I can probably optimize some more, but did not have time to do so yet. So take care. Camear applications seems to be a good test case (e.g. take pictures, switch to video mode or other non-default camera modes) |
Re: Bakuur's Over-clocking Guide for new comers
what kind of strange things??
can you please describe what exactly happens? i dont really use video recording but this might be a useful tip for others update : i tried taking a few pictures and making some videos other than the low quality images taken by the camera due to the night everything else is perfect |

Since you are now talking about devices being "permanently bricked," perhaps you will link to the messages where that is claimed, and perhaps you will let us know whether your N900 is in fact permanently damaged as you thought it might be. |
Re: Bakuur's Over-clocking Guide for new comers
@TiagoTiago please if your phone is bricked due to overclocking give us a link to that post and i will add it in the disclaimer but to be honest the only reason i overclocked mine is because i havent seen any bricked phones due to overclocking
|
Re: Bakuur's Over-clocking Guide for new comers
i don't think you can brick your device this way, if it doesn't like the kernel it won't use it. simple

according to jakiman. but i do reboot on stock or a custom setting in some reasons. i also have QBW widgets to tap if i wanna boot on stock or a custom setting |

1. Do you ever see the message saying that the overclock settings have not been made because the reboot wasn't natural, or words to that effect? 2. You are saying that you ignore Jakiman's recommendation and you get into a permanent reboot loop "in some reasons"? I'm not talking about one reboot. I'm saying that there is protection against a "permanent reboot loop". In my experience, there is. |
Re: Bakuur's Over-clocking Guide for new comers
@geneven
i truly apologize, i was trying to give a hand to support on your post that i Quoted :) in short, i agree with you |
Re: Bakuur's Over-clocking Guide for new comers
It would seem that the newer versions of Titan's kernel has a mechanism to override the default profile, but this was not the case with older versions. In any case, I will continue to use Queen Beecon to be on the safe side.

Re: Bakuur's Over-clocking Guide for new comers
Quote:
and yes try to use different profiles on your phone to find the most suitable for you and your phone isnt that what OCing is all about ? :P |
Re: Bakuur's Over-clocking Guide for new comers
the only reason someone would suggest setting a different default profile is to have a faster booting from your N900
so if you dont reboot that much then i suggest doing this Quote:
and i would recommend this to all |
Re: Bakuur's Over-clocking Guide for new comers
the problem with an automatic script is it will keep loading the profile even if it made the N900 crash
|
Re: Bakuur's Over-clocking Guide for new comers
Quote:
its really simple instead of choosing auto update just click on the profile you like it will allow you to have more than just one profile actually i have three profiles which i change between them constantly |
Re: Bakuur's Over-clocking Guide for new comers
It is not necessary to install rootsh. "sudo kernel-config ..." is sufficient.
your first call of kernel-config is "Kernel-config" but should be lowercase. |
Re: Bakuur's Over-clocking Guide for new comers
Hi Guys
My lower frequency always seem to be setting itself to 125 irrespective of whatever frequency I set. Any ideas on why this is happening and what I should do to avoid this. Cheers |

Re: Bakuur's Over-clocking Guide for new comers
haha so use the lv profile :p it will pump up the processor and consume less frequency :p

The voltage is calculated by [V = x * 0.0125 + 0.6] So when X=60, the voltage will be 60 * 0.0125 + 0.6 = 1.35V, not 60V. Source: http://wiki.maemo.org/Overclocking#Calculating_voltages 60V is an absurd voltage to go through any CPU. My post was meant to point you at that error ;) -iDont |
