Re: Overclock the N900?
 

If reports here can be trusted, the newer models are far worse, so hold on to that preorder model.

Re: Overclock the N900?
 

hi there! is it possible to use the usb host mode and overclock the n900 at the same time?

Re: Overclock the N900?
 

It's not the models that are worse, it's the users who have deteriorated. They don't seem to read the good documentation, preferring to make up their own, which seens to me not to make much sense.

Re: Overclock the N900?
 

I buy my n900 6month ago the newest english version. (comes with pr1.2)
Ulv or everything downvoltage not work properly. Upvoltage works perfectly and I have to change voltage for 900 until 1000 to works ok(even at 1150 works ok and stable on psx4m-for 1 minute check).
new voltages are:
700:60
750:60
805:60
850:60
900:60
950:64
1000:68
1100:72
1150:72

Re: Overclock the N900?
 

I am glad someone else has noticed this, I was starting to wonder if it was just me being an old grumpy git!!

I blame it on the influx of cheaper used handsets getting into the market.

Re: Overclock the N900?
 

Can some tell me how to get original power kernel settings back on reboot? I've got mine autoloading myprofile and have also gone throught this.... http://talk.maemo.org/showpost.php?p...postcount=4917
I wanna keep the kernel but do away with all the autoload and leafpad. Feel like i've entered a ton of stuff in x-term now n just want it back the way it was when i first install the power kernel. Thanks

Re: Overclock the N900?
 

If you have it autoloading myprofile, just delete myprofle, if I understand you correctly.

That file is probably in /home/user/.kernel

Re: Overclock the N900?
 

How do i find that file? Can't find it through file manager?
Thanks

Re: Overclock the N900?
 

use filebox with the show hidden files/folders option on. files and folders beginning with . are hidden.

Re: Overclock the N900?
 

Hmm i can see all old stuff now from previous installed stuff but no myprofile? searched everywhere too? Well if u have any other idea's let us know otherwise thanks anyway mate :)

Re: Overclock the N900?
 

how about you make a new myprofile with original frequencies?

sudo gainroot
kernel-config load lv
kernel-config limits "lower original" "higher original"
kernel-config save myprofile1
kernel-config default myprofile1

i think the originals were 250 and 600.

and you checked the .kernel folder? i found my myprofile there..

Re: Overclock the N900?
 

Found 2 files in .kernel folder, myprofile1 and my_fixed_oc. Deleted them both and rebooted, kernel-config show shows 500min 850max which was my "myprofile1" so its still autoloading it?? Any idea's?
Thanks

Re: Overclock the N900?
 

Sorry, just saw this post? Yeh was in .kernel folder, i'll make a new myprofile1 then. Good thinking batman! :D
I don't suppose you know how to stop userspace becoming ondemand do you? I'm trying to stop my cpu from scaling, fixed @ 900 but it changes itself?
Thanks

Re: Overclock the N900?
 

Holy Overclocking Batman :)
i think that if you set min and max frequency to 900 it stays there without scaling. there is also something about the scaling in Qcpufreq thread

http://talk.maemo.org/showthread.php?t=56757

edit. just saw the other thread you asked this.. sorry, but cant help with that. goes way over my head :)

Re: Overclock the N900?
 

I've kind of figured it out now, if u "kernel-config show" or have qcpufreq it show what your governor is set to (ondemand by default) ondemand lets your cpu scale available freq's on demand! The only way to change it (as far as i'm aware) is to install cpufreqUI and set governor to "userspace" apply and close. Then run xterm "kernel-config limits 900 900" BINGO! Hasn't changed since and the responce is much better! Even tho i followed jakimans... http://talk.maemo.org/showpost.php?p...postcount=4917 it still didn't work. Anyhoo, 2 more querys i had resolved for now! Cheers mate :)

Re: Overclock the N900?
 

Nope!? Scaling still won't stay fixed?? Halfway through the day the min freq changes back to 125Mhz WWWHHHHYYYYYY!!!!!!!!!

Re: Overclock the N900?
 

@natedog400
How's battery life when running 900MHz fixed?

Re: Overclock the N900?
 

Haven't noticed any difference! Just does things instantly like it should! But like i said... it doesn't stay fixed for some reason?

Re: Overclock the N900?
 

it's because of the phone app is buggy. each time u start the phone app the freq will drop to 125 mhz. this is a known bug and it is fixed in the power kernel by adding 125 mhz to the tuneable value avoid_frequencies. u want to load a default setting with kernel-config load default and then override the limits with kernel-config limits x,y. u don't need to load a userspace driver. Or u want to read the wiki page about overclocking. u want to try my tools too.

Re: Overclock the N900?
 

Oooooh thats makes sense now, although i don't quite understand how to add 125mhz to tunable value? So will it work with ondemand still? No need for cpufreqUI then? Could you tell me step by step PRETTY PLEASE!! :) I've even forgotton how to set a default setting which i've done before?? I'm learning. What tools u got?
Thanks

Re: Overclock the N900?
 

Anyone? How do you stop scaling?

Re: Overclock the N900?
 

Here is your answer Natedog. Check out the post from Jakiman - http://talk.maemo.org/showpost.php?p...postcount=4917

I recall adding it to my post on overclocking.
4. Jakiman offers some extra steps for setting the same MIN and MAX settings (e.g. 1000 1000). These are the settings I applied after I successfully completed step 1 and they work brilliantly. My N900 is super fast now and surprisingly very stable. I managed to open 56 applications (before it started to falter).

Re: Overclock the N900?
 

Hi, i have a question about the warranty when overclocking, so i mean if u do overclock, but something comes up and u want to take your phone back to the store for warranty fix, how do the people in the store find out that it's overclocked, if u flash your phone back to the way it was from the factory and install the nokia kernel again? thanks!

Re: Overclock the N900?
 

Hi Kids. If santa finds you overclocking, then selling them on ebay without mentioning your OC experiments, he will sneak into your bedroom at night and break your kneecaps.

Re: Overclock the N900?
 

I have followed Jakimans fixed overclocking guide and it seems to stay fixed at whatever i set it too ( 850, 900, even 1000) then after a while it scales back to 125 after I do a kernel-config show. I do that when i start to notice the phone starts being unresponsive or slow. I think maybe maemodder is the culprit since I add the avoided frequencies there which I thought would make it easier but no 125 still shows up after about an hour or so of fixed oct. So my question is are there any people out there with a fixed oc using maemodder without it scaling back to 125 after a while. Thank you appreciate all the help.

Re: Overclock the N900?
 

I don't know about maemodder but I have a quick and dirty fix for it but u have to do it at startup otherwise it got erased when u reboot. To fix this just write-protect the cpu min scaling value:

chmod 444 /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

If u have installed my tools u can uncomment that line in /opt/n900-tune-up/n900-tune-up/tune-up.

Re: Overclock the N900?
 

Thanks epitaph i entered that line in xterminal and it accepted it but nothing happened , is that correct? Or should I have seen something occur. My max and min are fixed at 850 for the time being so I will wait and see if it reverts back to 125 as a min. Hopefully this works and it stays fixed at 850. Thanks once more for your response. Also is the xlv profile the optimal profile to fix an oc too? It's the one Jakiman uses but I don't know if that's personal preference or what is recommended

Re: Overclock the N900?
 

I didn't read the wiki about power kernel but AFAIK all the profiles and xlv should add 125 Mhz to the avoided frequencies. If this doesn't work then I'm not up-to-date. I've found my fix during my studies with my tune-up scripts. it's because the phone-app wants to write this 125 mhz frequency into min scaling. The fix can only work if 125 Mhz isn't already written in min scaling. Hence u can check it with cat first:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

and then write-protect:

chmod 444 /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

Also u have to repeat this at startup and also I don't do phone app very much so I can't help u but the fix should work! Also in Linux when a command is succesful u don't get a feedback. I don't know what this is called! Also xlv is just an undervolting profile. It didn't work for me it is dependent of ur device i for myself use the default profile and 950 Mhz!

Re: Overclock the N900?
 

No one that I know of has reported specifially that Nokia has rejected any repair request because the phone had been overclocked.

Someone claimed that something in the phone changes color if it is overclocked, but as I understand it the phones come from Nokia overclocked anyway, so you'd think the color change would always be there.

Re: Overclock the N900?
 

U can verify it with ls. Here is the output of chmod:

chmod 444 /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
ls -lisa /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
-r--r--r-- /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

Watch the rights are read-only now. For super-user, group and everybody.

Re: Overclock the N900?
 

Yeah i checked with the cat command and it gave me an output of 850000 which i guess is 850mhz which is what I want so I think it worked. Thank you very much once more. Its been more than an hour now and it is still fixed at 850mhz :D. Now since Ihave to do this at every startup since a reboot will reset it , would it be possible to make it a queenbeecon widget command that i could just press ? If so how would I go about it, just edit the queenbeecon command and paste your command inside it ?

Re: Overclock the N900?
 

I don't know about this app. Most likely it would be to find the cause of that freq drop. If u suspect maemodder u should uninstall it. For me it was the phone app. U can try it yourself. Unlock min scaling and start the phone app or make a call. Min. scaling should get overwritten with 125 Mhz after that. It's quick and dirty!

Re: Overclock the N900?
 

Hi guys!
I work since several weeks with kernel power 46 at 1000 Mhz.
I am very satisfied of it.

However trying to using ethernet connection RJ45 over USB I
have a problem with my LogiLink USB 2.0 RJ45 Fast Ethernet Adapter.
All works fine with USB mount process (h-e-n) but at the command UDHCPC i got the following message :

SIOCGIFINDEX failed! : No such device

I have noticed that command IFCONFIG do not list any device with the name eth0.

I suppose that there is no driver for the a.m. device built in the kernel power 46.

Anyone can help me ??

Re: Overclock the N900?
 

I don't think it's an overclocking issue, which is the topic of this thread.

As I understand it, the kernel we use is the regular kernel with features added. I don't think it subtracts support.

Perhaps you can find a USB networking thread where this sort of issue is discussed. I'm sure you aren't the only one who has tried it with this kernel.

Re: Overclock the N900?
 

I've installed the power kernel and now the camera app doesn't work. It closes just after it launches saying 'operation failed'.

Is this a problem that anyone else has had?

Re: Overclock the N900?
 

Which Power Kernel have you installed?

Check out this post http://talk.maemo.org/showpost.php?p...9&postcount=96. It might be an incompatible application like Fcam... Remove it and see how you go.

Here is another link that may help you http://talk.maemo.org/showpost.php?p...0&postcount=93

Re: Overclock the N900?
 

Yes, it's probably Fcam related. It will work, but you need compatibility. I forget the details, but they are in the threads. Verify that's the problem and I'm sure someone will find the details.

Re: Overclock the N900?
 

I've already tried uninstalling Fcam and rebooting...the problem persists.

Firstly I had whatever the latest version of the power kernel is from extras-testing, then I tried updating it with the version currently in extras-devel to see if it made any difference.

I've tried uninstalling the power kernel as per the instructions on the wiki but that didn't work.

Re: Overclock the N900?
 

Unfortunately the link to the updated fcam drivers in the post that your second link points to doesn't seem to work.

Re: Overclock the N900?
 

hmmm... oc'ed to 500 950 ideal, 500 1000 ideal, and i noticed it crashes while playing videos, when plugged into tv, viewing cutetube videos..

.... which frequency is it stable in besides the default clock?
