Re: Overclock the N900?
 

ah thx for the info xD
Gonna wait for 31 and hope i won't get a error.

Re: Overclock the N900?
 

from maemo30, reverted back to maeemo27.

-so far, mostly apps with sounds (media player, canola etc) crashes, and tones/alerts are disbled

Re: Overclock the N900?
 

Sounds don't work and apps that aren't running are crashing here also :p

Re: Overclock the N900?
 

i just went to sleep and two updates already! awesomely fast! :D

Re: Overclock the N900?
 

Better stay with 27 :D

Re: Overclock the N900?
 

Everything work flawless for me with 30, no sounds or crashe issues :)

Re: Overclock the N900?
 

yeah for now, i believe v27 is the final one, maybe titan is just fixing the "deinstallation app" which is still buggy.

so far only the sound bug is one common present in the v30. we are almost there. i hope praying helps titan.

Re: Overclock the N900?
 

Just to share my experience so far with titans kernel, may be of help to some!

At first was using titans ideal settings at 500-800. I was having problems with the dsp when cpu was clocking down with the media player refusing to play videos. After some fiddling with voltages i managed to get it to work but found it slightly unstable.

I decided to give his xlv settings a go and this worked faultlessly up to 950Mhz with 500Mhz minimum. At 1000 i encountered problems when booting, kept freezing on second set of dots (after where boot video plays) :S so went to 950Mhz with no problems.

Would highly reccommend changing the transitions.ini file also, as this made the n900 very fast. This can be found elsewhere on the forums.

However the battery life was bugging me MASSIVE amounts. Had approximately 6 hours use from medium useage so went on a battery saving mission. I did the following mods and have seen a significant increase in battery life (approx 40%). This is the bit that may be useful!

Firstly i installed the simple brightness applet and usually found 2/5 brightness acceptable. App is useful for on the go change of brightness when required.

I found the AutoDisconnect app very useful, disconnecting the 3G connection when not in use.

Also from others advice on the forums changed the minimum frequency to 250Mhz which seems completely stable for me.

I enabled 'ignore nice load' in the kernel settings and changed the 'up threshold' to 95 and sampling rate to 350000. I beleive this means the processor will change frequency less and only under heavy load, increasing battery life.

Very pleased so far and would like to thank titan for the great work.

Re: Overclock the N900?
 

I think this command is very useful until new version :) :

Reverting kernel version to maemo27:

Re: Overclock the N900?
 

Just out of interest is anyone else using different govenor settings since setting them has been enabled in settings
+0.09?
Im currently playing with the conservative govenor, so far ive seen no negative effects on performance and its spending much more time at lower freqs (so maybe safer than ondemand) and im seeing the full range of available freqs (500-1000mhz in conky, its too early to tell if there is any effect on battery life yet but i believe it used less than usual over night, (6% drain over 12hours)

These kernels and settings are wicked. Thanks Titan for an amazing job well done

Re: Overclock the N900?
 

Every thinks works good here. no crash and no problème with sounds.

Re: Overclock the N900?
 

i believe i missed that part of changing governors. so still stuck with ondemand.

Re: Overclock the N900?
 

I'd love to try out conservative but unfortunately, there's nowhere in the kernel-config script yet to set sampling_rate or ignore_nice_load (they are only enabled for ondemand at the moment) and also the extra settings that are solely for the conservative governor (sampling_down_factor and freq_step) aren't yet implemented. Finally, avoid_frequencies is also only available for ondemand, although I leave all enabled.

Hopefully I might get chance to edit the script myself this afternoon..

Re: Overclock the N900?
 

Also has anyone been able to get cpufreqd to compile for the N900? I tried but the acpi.c script caused gcc to fail despite ./configure being successful. It's the only userspace governor that has been worked upon since January 2008 (in fact cpudyn hasn't been edited since my birthday in 2005!)

http://www.linux.it/~malattia/wiki/index.php/Cpufreqd

Re: Overclock the N900?
 

I put a brief discription of what the different govenors do a couple of pages back, they can be changed in cpufrequi (or you can now just edit your my config settings) but untill settings 0.10 they couldn't be made to stick in the settings by saving myconfig.
Just another parameter we're now able to tweek thanks to Titan, these kernels seem to get better every day, i look forward to seeing what we will be able to do next:D

Overclocking
 

well, the question is:
Does overclocking N900 damage your phone in a long term?

I live in Australia meaning its bloody hot here..XP soo i was thinking about overclocking it to 750Mhz.. will it damage my phone or it wont matter at all.?

Re: Overclocking
 

Read my guide. Basically, we do not know.
Technically, it might and can. But in reality, no idea.
N900 gets plenty hot even at default 600Mhz if pushed hard.
(no idea if it's cpu/battery/gpu/dsp that's generating the most heat)

Re: Overclock the N900?
 

From what ive read and watching conky seems to confirm this, conservative is set at up threshold at 80% & down at 20% with sample rate of 300000, hopefullt we will be able to configure these and ignore freqs in one of the next settings updates

Re: Overclock the N900?
 

i agree, i changed governors to conservative and only gives me negative effects on game emulators (slow response) all in all its great.

i can see from this day (or the day titan's kernels arise) that Overclocking will be official........:D

Re: Overclocking
 

playing VGBA and calls for about 20 mins makes my n900 warm enough (which is normal)

same as if overclocked @ 1GHz, taking into considerations, that heat wont damage the HW but overvolting may, and as jakiman says, "we do not know" and everything is still in theory.

Re: Overclock the N900?
 

OK people I have a problem - I updated the power-kernel package today and now my desktop crashes EVERY time I press the power button!!!

How do I fix this?

Re: Overclock the N900?
 

Which version have you updated to? some of the later ones seem to be unstable, i think the last stable one was maemo27 there are posts about downgrading the version to this one somewhere in the last 3 or 4 pages.

Re: Overclock the N900?
 

returns 2.6.28.10power30

EDIT:

Thanks managed to downgrade using command on previous page!

Re: Overclock the N900?
 

Yes, go back to 27. If you read a few messages you will find how to do it, it's easy and it works.

Re: Overclock the N900?
 

I was running the previous version fine - when was v28 and v29 released?

I don't know what version mine was running before I updated today - but I update quite regularly so can I assume it was v29?????

Re: Overclock the N900?
 

Then downgrade to maemo27 as told on page 369 by Titan.

Re: Overclock the N900?
 

It doesn't matter much which version above 27 you updated to. They all had problems.

Re: Overclock the N900?
 

I've just tried psx4all and at 1Ghz and it seems no different quite smothe but not as good as 1.15Ghz:D

I'm off out now so ill give sygic a try ang see how that runs, as i believe it uses alot of processor power.

Re: Overclock the N900?
 

Wow, next time I'll read here first before upgrading. Upgraded last night to v28. Went to bed. Noticed the N900 playing up a bit this morning.

Realized that sound wasn't working. Changed back to all stock settings, multiple reboots, no sound, no media playing, etc. Nearly had a heart attack. Started d/l PR1.2L at work, thought I'd have to reflash.

Reverted back to v27 and all is now good. Very scary. Anyways thanks for posting to get me back to v27.

Re: Overclock the N900?
 

after trying to downgrade, my n900 is dead. it's time to try pr 1.2 leaked

Re: Overclock the N900?
 

I was having problem with the maemo30 kernel as well. Widgets were dying from the desktop. (at default clock speed).

Re: Overclock the N900?
 

I can confirm widget disappearing and Contacts crashing with 28 and 30. Had to go back to 27.

Let me know if I can help debug somehow.

Bye
William

Re: Overclock the N900?
 

Without having to read 3752 posts, can someone summarize if this is safe to do on my N900 without melting it? Thanks :D

Re: Overclock the N900?
 

Yes, though the risk and responsibility is yours. See

http://wiki.maemo.org/Overclocking

Re: Overclock the N900?
 

It's all very odd because I installed 30 and restarted, and have had no issues thusfar (the dimming screen was my own fault as I had added it to a script that was run at startup, and subsequently forgotten about it)? I did install everything kernel-power related, including kernel-power-headers, which I don't think is brought in automatically if updating via app manager (could be wrong though)..

Re: Overclock the N900?
 

Thanks. Have you seen a severe effect on battery life?

Re: Overclock the N900?
 

Oddly enough, if you apply suggestions given in the Wiki, you can see a notable IMPROVEMENT in battery life!

Re: Overclock the N900?
 

I have more than doubled my charge of the battery. It can last up to 40h for me nowadays. Normally 30h+.

Re: Overclock the N900?
 

i missed the v29, are the sound bug present in that version?

Re: Overclock the N900?
 

Yes, its present in 28,29 and 30.
