maemo.org - Talk - Overclock the N900?

Sudo won't work use "/usr/sbin/kernel-config" instead of sudo. Also don't just go "root" from xterminal on first opening use sudo gainroot.

Don't ask me why the above works, it just does. My N900 is running at 1000 MHz quiten happily with what we are calling PR 1.3. :)

So I type in
''/usr/sbin/kernel-config''
and then ''apt-get install --reinstall kernel-power kernel-power-flasher''?

None of them seem to be critical so it should be safe to continue using power37 on PR1.3.
Just make sure to reinstall kernel-power after the PR1.3 upgrade

Code:

sudo gainroot

apt-get install --reinstall kernel-power kernel-power-flasher

@bulelet:
it's "sudo kernel-config", not kernerl (an Austrian word...).

When I type that in I get
''E: could not open lock file /var/lib/dpkg/lock - open (13 permission denied)
E: unable to lock the administration directory (/var/lib/dpkg/), are you root?''

Re: Overclock the N900?

hi titan thats just a typo. apologies on that

so anyways i tried the command again and heres what we get:

~ $ sudo kernel-config limits 250 850
Password:

You need to be "root"

Make sure you have rootsh installed.
Then launch xterminal, type root then enter and try again.

Daft question, and possibly leading you up a blind alley, and I could be wrong (I use xterminal, but understand only bits of what I copy/paste into it), but are you connected to the internet ? I ask because xterminal says "cannot be downloaded".

Yes I'm connected to the internet, it's not that!
It has got something to do with downloading I think. This works (and downloads):
apt-get install --reinstall kernel kernel-flasher

It is the kernel-power that's the problem.

OK, got it working by uninstalling first:

apt-get install --reinstall kernel-power kernel-power-flasher

apt-get install kernel-power-settings

Hi Titan,

for those of us like me who are currently using your power40 version on PR 1.3, the bugfixes probably don't apply then, correct?

If I would then want to downgrade to power37, would that best be done by simply using the "Deinstall Kernel" entry from the main menu and installing power37 fresh via the app manager?

Thanks in advance for your feedback.

so today i set to the LV profile, and set the limit range from 250~850 (following the instructions in Jakiman's guide).

After a reboot, all works well but my frequency is shown to be at 850Mhz........is that suppose to be right?? I thought it should be at 250Mhz and only go up to 850 if it is running processes or in high usage?? But i wasn't running anything and it's already set at 850Mhz......i can of course still set it to a lower frequency but i was wondering if this actually locks your phone to the max frequency?? If yes, then that's kinda no point for this??

I also tried to set the range from 250~300 and after a reboot, my frequency clock is at 300, so that sorta proved my comment above........is this suppose to be right?

If you watch your frequency carefully, it shouldn't permanently stay at 850. I don't know the details of how it decides. Your test didn't prove anything in particular except for you it seems to be going to the max after a reboot. That doesn't mean it will stay there forever. You should go back to 850 max and wait a few days while you check it from time to time. I just checked mine (I used kernel-config limits 500 850) and it started at 850 but now is at 500 according to HealthCheck, one of the best N900 diagnostic programs, and it is at 500 MHz. Now it is at 850 MHz. Just as I expect, it changes.

As far as releasing the version with the PR 1.3 fixes is concerned, my assumption is that those fixes will (first?) be implemented in the stable power37 version, hence my question to Titan.

Re: Overclock the N900?

Can I just confirm that if I update to PR1.3 I will not be able to overclock at the moment? By overclocking I mean simply installing the kernel for power users and the settings off the repos, I shall probably just wait in that case...

You can just do the OTA update without uninstalling. Or you can uninstall first then update. Doesn't matter, either way you will then be running the stock PR1.3 kernel and will need to reinstall the power kernel to overclock.

However...You will not be able to just simply reinstall the power kernel. It will fail due to some leftovers not erased by the PR1.3 update. To reinstall, you must first uninstall the power kernel packages. Do not try to uninstall from the app manager - it will fail. You can uninstall by either clicking the uninstall icon in the app tray (slightly risky) or by following the manual deinstallation instructions found here (safe):

If you mean the manual deinstallation described in the link, of course, many have including me. Works fine.

If you mean doing the OTA upgrade with kernel-power still installed, again yes, many have including me. PR1.3 installed perfectly. I then did the manual deinstallation to allow reinstall of the kernel-power packages. I'm now running PR1.3 with the same power37 kernel I used before.

Since I got my N900 in Nov 2009, I've done all upgrades OTA with absolutely no problems. Nothing has been lost or changed in the process, everything stayed perfectly intact as before. My device has never been flashed and runs great, stable and fast. I doubt I'll ever need to reflash the OS as long as I use it.

I have not done as you say. I have OTAd to 1.3, then apt-get install --reinstall kernel-power kernel-power-flasher.

Did my modules go haywire? How can I check? I did notice smb refuses to work right, could this be it?

Re: Overclock the N900?

My N900 has stacked at 500mhz. After pr1.3 update I installed the power kernel and after restored the stock from nokia. From then it's stacked at 500mhz either with the stock either with the power kernel. I tried echo the max and the min freq & qcpufreq to fix the limits but nothing. Any idea?

Crashdamage

2010-10-28 11:20

Re: Overclock the N900?

@ndi and @anapospastos:
As I said before, you must do the deinstallation of kernel-power as described in the link I provided before you can reinstall the kernel-power packages. Or, IOW, reinstalling the kernel-power stuff will fail unless deinstallation is done first. I can't be much clearer than that.

To check what kernel is actually running, open a terminal (no need to become root) and type:
uname -r
Hit enter. It will probably return:
2.6.28.10-omap1
...which means you are running the stock kernel. If the power37 kernel is running it will say:
2.6.28.10power37-omap1
If you want more details, use uname -rv ('v' for verbose).

And don't forget reinstall 'kernel-power settings' also or 'kernel-config' commands will not work. If you had custom profiles that you saved those will not be touched by either the RP1.3 upgrade or kernel deinstallation. So when you get the kernel-power stuff reinstalled successfully you can use them just as before.

I properly reinstalled the power kernel and the kernel-power settings and my cpu usage is very high. Only conky opened and it junps between 500 and 900 Mhz all the time.
With PR 1.2 I had 250 Mhz 80 % of the time.

Re: Overclock the N900?

okay now me , im getting some strange bugs.
as mentioned in a few other threads before, here my problem i hope someone can help me.

my usb port broke and i sent my phone to nokia, they replaced my devise. now with the new one and PR 1.3 and the Power40 i am not able to go any higher clock than 850Mhz. (testet power37 and PR 1.2 too, same thing)

here some details: i am using titan v40 and lv. its set to 250 850 where it runs like a charm. if i clock to 250 900 (1000) it immediately resets. still lv, it does work with 250 1100 (1150) where it crashes just randomly after a few mins.

Same with ulv and xlv where going any higher than 900 it crashes (like in the same way mentioned before)

The difference in those profiles is ideal: when typing "kernel-config load ideal" - without having changed anything in that profile before (just having the default one), it immediately crashes too. i am not able to set anything in thaht profile.

My question is, did nokia replace my phone whith a lower quality one? PLEASE Help me if u have ever experienced something like this. thx in advance

This doesn't mean the phone you got is "lower quality" in general than any other N900.

You should be happy your N900 overclocks at 850. That isn't guaranteed either. I overclock mine to 850 and have never tried higher. 850 is a good safe setting for most people.

Yes. When you are reading the overclocking docs, pay special attention to the Jakiman intro to overclocking document. He has a chart estimating the percentage of BRAND NEW N900s that will fail at what overclocking speed. You will be interested to note that the percentage of BRAND NEW N900s that fail to overclock at 850 is NOT 0!!

You might be able to learn something about overclocking in the docs.

Not everyone can, if you check other posts you'll see that. How well your (or anyone else's) device tolerates overclocking, voltage changes, etc. is strictly the luck of the draw. You could have just as easily gotten a replacement that would take whatever you throw at it in stride. You just didn't get lucky with your replacement unit, simple as that.

Re: Overclock the N900?

I have been chatting with Lehto and he apparently runs his at 1100Mhz fixed and noticed that it is much smoother than ever before. (as it doesn't need to scale back down to 250 or 500 speed etc)

So I tried it on my N900 today. Just fixed at 1000Mhz. It's either 0Mhz or 1000Mhz. Using xlv voltage profile with every other supported frequency is in the avoid list. What can I tell ya. It's smoother with less lag than ever before! I'm surprised how responsive my N900 became. I've watched an xvid avi file for like an hour straight and had zero issues still. (my phone never had issues at 1Ghz anyways)

So to those who want that extra responsiveness, try taking out the cpu frequency scaling altogether. (maybe even fixed at 600Mhz or 850Mhz if your phone can't do 1Ghz) I'll bet you will notice it being a little more responsive and lag free. I did. =)

Here is some simple steps I've written up on how to do this:
(I wrote this to cater for beginners also but still with some assumed knowledge)

0. Install an app called "leafpad" from HAM/FAM.
1. Overclock your N900 normally to what you always overclock to.
(will assume that the maximum is set to what you want as fixed)
2. launch xterminal
3. RUN: root
4. RUN: kernel-config min max (where min & max is the desired fixed frequency)
eg. kernel-config limits 1000 1000
4. RUN: kernel-config save my_fixed_oc (or to any other profile name you want)
5. RUN: leafpad /home/user/.kernel/my_fixed_oc
6. From leafpad, we need to edit FREQS line to only show 2 frequencies:
eg. FREQS="0:20,90 1000:60,500 "
(above example means it only allows 0Mhz or 1000Mhz. exact numbers may differ depending on which overclock profile u used. At the end, just ensure you have 2 values in there. 0 and max value you want.)
7. Save and close leafpad.
8. RUN: kernel-config load my_fixed_oc
9. RUN: kernel-config show
(it should show both min and max frequency with same value)
(it should show all other supported frequency in the "avoid frequency" lline)
(it should show only 2 frequencies you set in the "active frequencies" line)
10. You can now use "my_fixed_oc" profile with Queen Beecon Widget etc.

DONE. Now even if you make a phone call etc, it'll still always be locked to max. =)
