Re: Overclock the N900?
 

Incidentally, a day after I asked the above question, my N900 is now dead as dead can be.

I'm guessing eMMC/rootFS corruption as the N900 simply gets stuck in the loading screen after the Nokia logo at boot, although I COULD flash the rootFS.

So, this related to rootFS / eMMC data write corruption due to undervolting? Because I can say that this is the first time I've seen an N900 die DUE TO USE rather than being dropped or anything.

Re: Overclock the N900?
 

...I think - and Titan may think finally - new challenges are up; the "fCamera" does not seem to run with Titans v37 kernel; and who is willing to miss the extra power Titan gave us taking DNG RAW pictures; Titan - your turn ;-)

Re: Overclock the N900?
 

Possibly related. Hard to say. Technically, you can't say it died as you can revive it fairly easily. :p
But yeah, I don't recommend too much undervolting. It's the same as too high frequency.
If the cpu can't handle the frequency at its given voltage / heat, it will start generating too much errors.

Re: Overclock the N900?
 

I cannot install Enhanced kernel (nor the settings)

It gives me a message "conflic of the aplication packets" (or something like that - Im translating from polish ;) )
Under the specifications menu (still - or something like that ;) )it is listed that the problems are with kernel-modules-maemo and kernel-maemo.
I have pretty much clean system, some apps and games (also rootsh)..

Any ideas?

Re: Overclock the N900?
 

I am new to this forum as i just got my N900 today. I have been reading the progress of this thread when it started but have not kept myself updated with the progress recently.

So sorry if my question seems dumb. Please bear with me.

I am aware that the N900 stock frequency is 600MHz and the minimum frequency is set at 250MHz.

I would like to know if it is possible to keep the same stock frequency but drop the minimum frequency to 125MHz. Which kernel should i use to get the desired results?

Also will doing this help increase the battery life?

Re: Overclock the N900?
 

N900 has a "stock" configuration, with a minimum of 250 and a maximum of 600.

If you want to configure 125-600, it's possible, but:

a) 125 was disabled by Nokia due to instability
b) phone sleeps at 0, not at 250. Lowering to 125 will only make it drag its feet
c) these and more answers in the wiki.
d) battery gain is minimal, if not negative.

Re: Overclock the N900?
 

If I overclock using this tutorial "http://talk.maemo.org/showpost.php?p=595582&postcount=774"

Will I still be able to use the AM and updater?

Re: Overclock the N900?
 

Didn't I just answer this identical question in another thread? Please don't post the same inquiry in more than one place. We read this stuff and we don't need to read the same stuff over and over. We already see the same questions over and over anyway, because newbies post the same questions again and again even without your help :)

Re: Overclock the N900?
 

The conflicting packages message is probably because you also installed Fcam. This problem, caused by Fcam, has already been fixed by our hero Titan. I'm not sure where the fix is other than in the thread about Fcam and Titan's kernel, but I'm sure it will be available soon in the normal App Man place, if it isn't already.

Re: Overclock the N900?
 

Sorry I didn't notice. I didn't receive the email telling me that you had replied to my post.

... and I wanted to post in this one since this is the main overclocking thread but mistakenly posted on the other since the thread titles were so similar.

Re: Overclock the N900?
 

I have uninstalled Fcam and still cannot install.
There must have been some other changes..
Also Titan made a fix to make Fcam work while having Advanced kernel installed, so theres still no fix of which I know for a situation like I have.

Re: Overclock the N900?
 

hello decided to try overclocking today and i can't get the titan's kernel to flash properly. ive tried reinstalling using apt-get install --reinstall kernel-power kernel-power-flasher but when i shut down and boot it stays on the nokia screen then shuts off. If i boot again it boots with the regular kernel. Am i doing something wrong?

Re: Overclock the N900?
 

Is this your first time trying to Overclock the Nokia N900?

if so make sure you install rootsh and then Enhanced Linux Kernal for power users.

Restart then install enhanced linux kernal for power users settings

restART again then go to xterminal and type

"Sudo gainroot" then click enter and then type "kernel-config load ideal"

now to make sure all has worked type "kernel-config show" in the same window

if it says 5oo 800 then it has worked. if you restart now then you will have to do it again

if your phone shutdown or hangs then do this again and type "sudo gainroot
kernel-config load lv
kernel-config limits 250 850" (pressing enter after every line)

dont include the """"" when typing in xterminal :)

if it works for you then thank me :)

Re: Overclock the N900?
 

No problem. Note that if you want to delete a post -- for example if you find a better place to post it -- you can choose to edit the post, then delete it. I have gotten rid of many of my dumb posts that way.

Re: Overclock the N900?
 

Is there any news on the maemo38 update?

Re: Overclock the N900?
 

Last news is this one http://talk.maemo.org/showpost.php?p...postcount=448; the "critical" issue regarding v37 and the big news "fCamera" has been somewhat solved with titans package of the "fcam" kernel modules...

Re: Overclock the N900?
 

Thanks but i knew that. I also saw that the update would come during this weekend to the repo. So i was wondering if something had happend. ;) I guess it will come in due time.

Re: Overclock the N900?
 

OC'd my N900 to 500 and 1000Mhz and I'm wondering when it switches to 500Mhz? In standby mode?

Anyways, many thanks to Titan:D

Re: Overclock the N900?
 

it will switch to 500 whenever the processor isnt processing anything heavy like opening a program, it will switch to 500 when you lock the device or leave it for sometime.

if your doing something in a program or playing music it will stay at 1000 or 850, whatever you have it OC'd at.

or when the cpu reachs a percentage of use

Re: Overclock the N900?
 

so I'm assuming since you thanked me, that it worked, and your N900 is now overclocked? :)

btw thanks for the thanks :)

Re: Overclock the N900?
 

yeah its my first time :) i started over and did what you said and got it working haha thanks! (i also thanked you too)

Re: Overclock the N900?
 

good good, remember if your phone is switched off it wil revert back to its normal settings, i suggest you save the code in a note on the phone for future use.

you can have it auto run the code at start but I suggest keeping it that way to save against having a infinite reboot loop.

Re: Overclock the N900?
 

Using titans kernel, if an unexpected reboot occurs, the default kernel is loaded. This is done as a precaution to stop reboot loops.

If you'd like ideal/lv, whatever to be loaded on startup all you have to do is open x-term, and type

so as an example I use LV oc'd to 250 - 1000, this is what I type to obtain this.
This loads the profile 'myconfig' at startup.

Re: Overclock the N900?
 

Followed this and everything worked!

One question, the "ideal" set the minimum frequency to 500. Does the lower voltage and higher frequency is better then the default voltage and 250 frequency?

Re: Overclock the N900?
 

Yes. This should be in a FAQ somewhere, it gets asked all the time. In general, read and trust the basic docs and settings.

Re: Overclock the N900?
 

Yes, it is better. Trust Titan. 10's 0f 1000's do with their N900's :)

BTW thanks for thanking me for my help :)

Tried to find the FAQ but failed :(

Re: Overclock the N900?
 

It is explained in the battery section if i remember it correct.

Re: Overclock the N900?
 

Looked again and did not find.
My question was about battery life...

Re: Overclock the N900?
 

If your a heavy user and your constantly 90% of your time playing games the batt will go down quicker than sual, but if you have your phone idle 90% of the time it tends to last longer than before the overclock I find.

Re: Overclock the N900?
 

The lower voltage is what you are interested in here. The frequency is the amount of clock cycles the processor goes through in a second, in this case 500Mhz. This is simply the speed at which it processes information.

The voltage is the draw from the battery and if you are running on a lower vCore (the core voltage running through the proc) then you are pulling less power from the battery - therefore you will see a slight increase in the overall battery life. As Pyro says though, if you run high end applications and games constantly then you will still see the battery dying rapidly - even though the vCore is no greater than the standard pull, therefore the battery will die at the same rate more or less.

Lower the vCore, increase battery life (albeit slightly), increase the vCore to gain stability, decrease battery life (albeit slightly as well).

Read up on overclocking and what it is, titan wrote a configurable kernel to allow for overclocking but bear in mind, you *can* fry your processor if you don't know what it is, how it works and what it is doing to the internal workings.....

Re: Overclock the N900?
 

Is there a permanent solution for this. I mean you need to type the code everytime you restart. So it is possible to make this the default settings so you dont have to enter the code everytime.

If you want to go back to normal settings then just select that option & if you want to use kernel settings that select that button. Life will be much simpler.

Re: Overclock the N900?
 

I made a direct link to the section in the FAQ. http://wiki.maemo.org/Overclocking#U...voltage_tables

Re: Overclock the N900?
 

Yes, there is but it is rekommenden to use a Queen Beecon windget instead as HugoSon pointed out. Incase you made a bad setup not risk the reboot loop and reflash.

To make a setup default you could:
1. sudo gainroot
2. kernel-config default <profile>

Where <profile> is your chosen setting like the ideal.

Follow my steps here: :D

Re: Overclock the N900?
 

sorry didn't know you asked me a question.

Hugoman has answered your question anyways :)

Re: Overclock the N900?
 

Thanks I do know but prefer to type it in every time at startup.

Re: Overclock the N900?
 

A clearer answer is in the Jakiman doc:

================================================== ===

Some extra notes:
ideal profile avoids 125 and 250Mhz. So loading ideal profile will only go down to 500Mhz as its lowest frequency. This is intentional and is found to make you rn900 more responsive but not use more battery or harm your N900. (due to lower voltages)

The Jakiman doc makes further suggestions in the same section if you want to try setting the frequency lower anyway.

Re: Overclock the N900?
 

Does overclocking void warrenty

Re: Overclock the N900?
 

Yes. Might be worth reading up a bit before you ask questions like this.....
