Re: Overclock the N900?
 

Same kernel, starving profile. So far at 805mhz, device never got warm.

Re: Overclock the N900?
 

If you start crashing unexpectedly AT ALL with that configuration, I think it would mean that you are NOT ok. If you seem to be fine, without a lot of overheating, I would guess you ARE ok.

You seem to imply that the combination of that frequency with starving is especially hazardous. I think that they are two separate issues. Starving doesn't work for me, for example, even without overclocking (I am pretty sure). Everyone has to test and judge their own device.

I think I could probably go with 1+ Ghz overclocking, but I stay with 850 mhz. That makes me feel safe. And ideal voltage, which is much as I can do without crashing from time to time.

Re: Overclock the N900?
 

So far I never had a crash when choosing the frequency at starving. It works stable at 1.15ghz, I tested for max of 10 min and went back to 805mhz imediatelly, and never moved from there. I wanted to hear sideffects if there are any like heat issue at the higher frequency. Knowing that my device runs stable at 1+ ghz with the lowest votages makes me wanna increase. It's eating me inside :(

Re: Overclock the N900?
 

ive been running at 850 with the slightly tweaked voltages per jakimans recommendation for a month or so now, and today I noticed it doesnt go above 600. stupid slow phone... a sudo reboot didnt change anything... ill try rebooting again... and if it still doesnt work, ill re enter the terminal command... has this happened to anyone else?

Re: Overclock the N900?
 

after a few days with LV 500-900MHz /opt is ****ed Dx

Re: Overclock the N900?
 

I have no idea what you ment :p

Re: Overclock the N900?
 

after a few days using the Low Voltage profile, with minimum clock 500Mhz and maximum clock 900Mhz, the /opt partition has gone to hell

Re: Overclock the N900?
 

Hi just picked up a n900 was following a guide to overclock and install a custom kernel but when i select Enhanced linux kernel for power users (settings) from application manager it says there is conflicts with applications packages:

Kernel-modules-meamo
kernel-maemo
Kernel-modules-meamo
kernel-maemo

That wasn't a typo application manager actually says both of them twice so i guess i need to remove these packages before installing the custom kernel or does anyone know what could be causing this and how to fix it I've read a couple post on this thread about the problem but didn't see resolve the problem.

Also i don't have fcam installed.

Thanks for any help in advance.

Re: Overclock the N900?
 

Been running mine for a few week at 950....with no issues..ha so far anyway. No crashing, freezing or heat.

And here in UK weather is cooling down so thats the heatsink covered...:D

Re: Overclock the N900?
 

besides having to reinstall lots of stuff, it seems i might also have caused some permanent damage, already the second random reboot now...

Re: Overclock the N900?
 

Backup your docs and do a full sw reinstall..run std settings and maybe ok?

Unlikely to be hardware...its pretty robust.

One thing though, whats the idea behind low voltages and then trying to max the processor out? Seems illogical to me to do that and expect stability....

Re: Overclock the N900?
 

Hello.

First time I OCed N900 using kernel v37 and it went very well. I've been using it for some time. A few days ago I decided to give NITDroid a shot.

So I upgraded kernel version up to 40,installed NITDroid. Played with it but decided to delete. I uninstalled it using instructions.

So I noticed my OC doesn't work anymore. Yesterday I deinstalled enhanced kernel using wiki guide.

Right now I'm running N900 on the stock kernel. But when I try to install v37 from extras repo it says "missing some dependancies blablabla". Log shows I don't have kernel-power-flasher. But I didn't manage to install it via terminal.

Could somebody help me please?+) Thanks in advance

Re: Overclock the N900?
 

Have you tried the devel version? It has some fixes, including fcam conflicts, IIRC

Re: Overclock the N900?
 

ok i have a so called "problem"... when i load "ideal" profile, it put my lower frequency on 500 MHz.... but after a while, it lowers it to 125!!! O_o :P
thats odd... it says that it should avoid frequencies 125 and 250...
and oh yeah: my phone is slightly lagish at those moments.... but when i load AGAIN ideal profile, it go back to 500MHz, and everuthing is allright.... TILL the moment it again lowers the lower freq to 125... :P
???????????????? any ideas what is wrong???

Re: Overclock the N900?
 

I installed v40 from devel, but it seems like it's not enabled after reboot.

Do I need to write something in terminal to make it work?

Re: Overclock the N900?
 

Terminal tells me this:
Usual power off and then on doesn't work. Could somebody explain me what exactly to do to enable the enhanced kernel?

Re: Overclock the N900?
 

IIRC, Phone app re-sets limits to 125-600 every call. I remember it being fixed at some point, but now when or where.

Try to see if it resets when a coll comes in or goes out. If Phone app is the problem, at least you know what we're looking at.

@qwenjis

I did nothing. Installed, rebooted, then CLI reported all is well and was able to call on kernel-config limits after gaining root.

Any errors during install? Did you use the terminal and apt-get or HAM? HAM eats some errors and warnings.

Re: Overclock the N900?
 

Tryed terminal, fapman and default application manager. No difference.
It shows enhanced kernel is installed, same for settings app. But the kernel is still the stock one.

No,no errrors at all.

Re: Overclock the N900?
 

Any conflicting apps? Several could impact this, like packages that boot off another partition, other OSs, boot menus, etc. Any possible conflicts?

Re: Overclock the N900?
 

I had NITDroid but I deinstalled it exactly as written on the project site.

Apps..Well I didn't install any new, just some updates. Is there any way to check possible conflicts?

Re: Overclock the N900?
 

Well, since you don't want to hear about reflash (who does), perhaps you should ask around in the NITDroid thread, maybe they know better. IIRC, they don't both work on older versions or something. Or maybe that was fcam? I've lost track. All I know is I can't NITDroid because of something I have and I have both Titan's kernel and fcam.

Re: Overclock the N900?
 

now running 250 - 1150 for a few weeks :) ...so far no problems at all....battery life is good.......no heat probs although I live in a country which is warm throughout the year

Re: Overclock the N900?
 

Just going to 700mhz max was a huge improvement. :o

Re: Overclock the N900?
 

Dear friends

I have a little problem. I had overclocked my N900 yesterday to 250-1150 mhz range with "Enhanced Linux kernel for power users (settings)" using Jakimans guide to overclocking

http://talk.maemo.org/showpost.php?p...&postcount=774

Then i had installed the nitdroid using the auto installer package and slept :).. waking up in the morning, I found out that the Nitdroid had successfully been installed and running.. but latter i found out that the overclocking is no longer available on Maemo :(.. I cant use the commands to overclock neither finds a way to reinstall the custom kernel using the "deinstall kernel" package and following this thread

http://wiki.maemo.org/Kernel_Power#Deinstallation


Although I had tried to manually deinstall the kernel and reinstalling it, but its not working now... Can nybody help me on this..

Regards

Re: Overclock the N900?
 

Have a look at this

Re: Overclock the N900?
 

thnx dude bt i m referring to overclock the Maemo part.. not the NitDroid one :)

Re: Overclock the N900?
 

This may help... http://wiki.nitdroid.com/index.php?t...-Autoinstaller

It explains that kernel-power is compatible with Multiboot from version 39 and onwards.

Once run, when you reboot with your screen open, you will be give 3 booting options instead of the two. Select option2 to boot into power-kernel with overclock.

Hope it helps

Re: Overclock the N900?
 

Hello everyone, Im new to overclocking and just OC'd my n900 today using the following settings:

and saved that as the default.
I am wondering if it should be fine to be ran 24/7 and not do any damage to the hardware? ( I want to keep this device as long as possible! )
If not, what is the recommended setting to run 24/7 stable and harmlessly?
Thanks a lot!

Re: Overclock the N900?
 

Hi All,

while my nitdroid was working excellently,I came across a horror today (thankfully over now but..)

the sequence of my multibooting n900 is following:

-since I started choosing option 2 in the multiboot (power kernel 40) and overclocking to different freq's (ie using 250 850 for 1 hr then changing to 250 1000 for some time then shifting back to default 250 600 mhz without rebooting) my n900 is becoming quite unresposive

-today when i rebooted..to shift to the pk40,there WAS just the nokia logo screen only deadlooped !!!

-then I took out the battery and rebooted again to the same result...

-on the next reboot I choose nitdroid which loaded normally but it gave a message," damaged sd card"

-I thought i ve to reflash (i ve never done b4,+ scared of having to download and set up device all over again)
-luckly on the nhext reboot I got back to maemo choosing option 2 but I got a notification on the maemo homescreen stating ,"warning: custom kernel failed to boot after reboot ??"

1-Can any dev pls help me on what I am doing wrong (in terms of oc etc) &

2-What should I do to make sure I dnt ve to reflash and increase n900 's speed..

Re: Overclock the N900?
 

hi!

its been quite a while since i ran through this thread for some OCing info.

earlier this morning, i bumped up on playing the "auto-load" feature of overclocking.

some call it permenent overclocking (i may be wrong or really i am) so here is what i notice.

i set ideal settings to clock @1GHz (500 - 1000) then save it as 1000-ideal.

then, by doing kernel-config default 1000-ideal code, my custom settings will be loaded at boot.

my question:
-why does cat /sys/devices/system/cpu/cpu0/cpufreq/stats/time_in_state command shows a "30" point value on the 250000 freq? it is constant at that point after doing 3 reboots. (i have 125000 and 250000 set to avoid freqs)
-is that a defense mechanism of the kernel (maybe preventing to auto-load a non-stable frequency)
-or does the n900 boot up @stock kernel for "30" (assuming that 30 is in milliseconds) and after that, will auto-load my custom settings?

thanks :)

Re: Overclock the N900?
 

Having this same problem, i updated power kernel through app manager to version 40 i believe, and now i cannot use any kernel commands in x terminal i get the following message
This kernel version 2.6.28-omap1 is not supported, please make sure kernel power is installed and running.

Tried the reinstall command it gives, but it fails, have tried deinstalling the kernel and reinstalling but still doesnt work :(

Anyone else had this problem and solved it?

Re: Overclock the N900?
 

Sort of. Had this problem when I installed Nitdroid. Nitdroid installer is seriously buggy so I deinstalled and went back. Had to remove Nitdroid and everything else Nitdroid installer installed. Then reinstalled Power Kernel and rebooted. Took a few reboots then it sorted itself out.

Re: Overclock the N900?
 

Since installing the power kernel i get static bursts when different apps take control of the sound. So like if i am listening to music and i get an IM or SMS there is a bit of static (on built-in speakers) before the alert sound plays. Also, when i have external speakers plugged in to listen to music, the alert sounds do not come out of them. Instead they play on the built-in speakers. This is odd, because when i am in the car using the FM transmitter they play over the radio just fine with no static.

So to recap:
Headphones/Speakers plugged in = Static pop on built-in speakers and playing of IM/Chat alerts and sounds on built-in speakers.

No phones, just using built-in speakers = No static pop.
Using FM transmitter = no static pop, chat/IM sounds play through radio as expected.

However, even in the situations where there is no static and it opreates as expected it still isn't as smooth as it was when using the stock kernel.

Kernel is version 2.6.28meamo40
Happens at stock speeds and with speeds set to 125/600, 250/600, 500/600, and 550/750.

Using ULV profile. Have not yet tested on the LV profile.

Re: Overclock the N900?
 

Not had that....I'm running at 1ghz on ideal. Maybe you should switch?

Re: Overclock the N900?
 

I tried ideal as the first profile to try out. It rebooted on it's own in a fit of spazzims within moments of booting. Had sound issues and the cell radio stopped working. That was at stock speeds. Saw others on the boards mention that they had reboots from trying to run with too little power, so i switched to ULV and haven't had a random reboot yet. Aside from the weird sound glitch everything is going pretty well.

Re: Overclock the N900?
 

got i to work by updating in xterm and did apt-get install kernel-power-settings.

Re: Overclock the N900?
 

I've switched my phone over to the LV profile with limits set to 125/900 (since according to kernel-config show this puts the DSP at 500 vs 430), and now i don't appear to be getting the static when testing with headphones (vs the speakers i have at work), but now it is playing the alert sound through both the headphones and through the external speakers. I don't mind this since it ensures you hear it if you have your ear buds out as well as if you have them in.

But it's interesting behavior that i thought you might want to look into. My guess is that it has to do with the DSP speeds.

Re: jakiman's N900 Overclocking Guide
 

Uuh... headache on at my end here. Reason why: I use a slightly modified ideal-profile, I made it go from 250MHz to 1GHz, thats all. But I suffer severe battery drain. About 1% per minute!
If I close all apps, let the device rest, and have a look at Conky, the device idles at 250MHz with about 3-5% load on the CPU and all 8-10 secs it upscales to 1000MHz for 2-4 secs with CPU load still around 4% and then back to 250MHz.
I dont have any special background daemons, watchdogs or services running. All apps closed. Where does that jumpy behavior come from?! Conkys graph also is completely level, no peaks or exceptional stress, just upscale to 1GHz and back again.... Any ideas?

Re: Overclock the N900?
 

I think i found a bug...
I am using kernel power and setting 37 version

When i set the custom voltage profile Min freq 125 and Max 256.
While using it i see cpu frequency going upto 500 everytime and keep jumping from 125 to 500. Otherwise if i fix other frequencies it follows the command properly.

Any suggestion how to avoid 500
I am checking the minimum voltage tolerable.

Another question If i decrease Zero frequency voltage how it is gonna affect the system. It is also confusing because Titan ideal profile does not have zero frequency supported and so no idea about its voltage
