Your N900 Maximum Overclock
 

Hello all OC heads, please post your maximum stable overclock that your N900 was able to handle, and what voltage it needed to get to that speed (ideal, starving, lv, ulv and so on), just wanted to see the percentage of good Cortex-A8 samples, thanks all :D

Mine anyway was 1150Mhz stable with starving voltage, all running well, but my 24/7 is 125 - 900mhz starving :cool:

Re: Your N900 Maximum Overclock
 

Some of us don't overclock like Death Race 2010.

Re: Your N900 Maximum Overclock
 

Never got starving worked :D it always freezes , now running lv 250-900 Mhz 24/7 so far so good
didnt go to 1000mhz since many people report there is no real performance gain between 900-1000

Re: Your N900 Maximum Overclock
 

1150mhz for me too, using the linux for power users kernel. overclocked, forgot about it, it was fine until i realised and took it back down a bit...

Re: Your N900 Maximum Overclock
 

most of the time is @600-700mhz, my maximum is 1150mhz, only use it in gaming

Re: Your N900 Maximum Overclock
 

i oc'd to 1000, was happy with it so stayed there.

Re: Your N900 Maximum Overclock
 

Running fine here at 1150... but now, summer is arriving! 250-850 is nice for me, 950 at some points.
Some little help: until now, I always can set 600mhz with cpufreq widget, but now, if I select 600, it is ignored and last speed maintained (lower speed I can activate is 700 mhz... someone has this "issue"?

Re: Your N900 Maximum Overclock
 

Hi!
I use 1.15GHz clock almost all the time... because of MyPaint.
But when I use Net and GPS or watching videos...
I switch clock usually to 600Mhz..

So far MyPaint works great with 1.15GHz clock.

And with MyPaint there is noticeable performance gain,
between 900MHz and 1000MHz and it is quite a lot actually..
and even more with 1150MHz. clock.

Drawing and painting with MyPaint pencils brushes
is liquid smooth experience... with 1.15GHz clock.

Re: Your N900 Maximum Overclock
 

How do u keep it at a certain clock without doing it through the terminal every time you reboot?

Re: Your N900 Maximum Overclock
 

You must edit the kernel according to the limits you want to use.
Let's say you want to stay on 250-805 limits, using the LV kernel:
sudo kernel-config load lv
sudo kernel-config limits 250 805
sudo kernel-config save lv8
sudo kernel-config load lv8
sudo kernel-config default lv8
This way, even after reboot, you'll stay in 250-805
Hope it helped

Re: Your N900 Maximum Overclock
 

The whole settings reset after reboot is just to protect your N900 from bad overclocks, so you don't need to reflash everytime your overclock fails, anyway check this post http://talk.maemo.org/showpost.php?p...&postcount=774 go to the bottom of it and you will find how to make custom widgets to apply overclocks on the fly, cheers.

edit: or just do what gtessier00 said if you are sure your overclock is all stable and good.

Re: Your N900 Maximum Overclock
 

Sweet deal. Thanks.

Re: Your N900 Maximum Overclock
 

I am using "Desktop Command Execution Widget".

It is very handy for me.

Re: Your N900 Maximum Overclock
 

Oh damn I voted before reading your post.

I voted for 900Mhz, but I never even tried over that.

Sorry :c

EDIT: OK I'm at 1000Mhz now.. oddly warm this thing, I think I'll go back to 900MHz

Re: Your N900 Maximum Overclock
 

my 24/7 is 1150mhz since overclocking was discovered

Re: Your N900 Maximum Overclock
 

I'm using Fecn's dbus scripts to automatically adjust the clock speed according to temperature:

http://wiki.maemo.org/Overclocking#U..._.28by_Fecn.29

Works great, and this way the CPU is never cooked... ;)

Re: Your N900 Maximum Overclock
 

1150 works here using "ideal" profile.

Note: I did need to pump up the voltage a little for 850MHz and 950MHz speeds, but 1000, 1100 and 1150 voltage settings are same as "ideal".

I'm likely to settle for 1000MHz as for 24/7 setting.

Re: Your N900 Maximum Overclock
 

Mine won't quite make 1150, but runs 1100 stable at 72 voltage.

I usually run 1GHz @62 -- 60 wasn't stable, 61 seemed to be, so I gave it an extra kick to avoid surprises.

Re: Your N900 Maximum Overclock
 

I'm at 1000 MHz @ 56 without apparent trouble.

Re: Your N900 Maximum Overclock
 

So I voted for 850, but I've never run at a higher rate. If you are thinking that everyone voting crashed at higher than the max they listed, I think several votes such as mine don't reflect that. I have a feeling that mine will do 1Gh with ideal, but don't intend to try.

Re: Your N900 Maximum Overclock
 

now we have 70 N900s for the overclock sample, not bad for one day, but here are the results in percentage until now, with hopes that we reach 100+ samples.

700/750Mhz - 100%
805Mhz - 98.57%
850Mhz - 95.71%
900Mhz - 84.28%
950Mhz - 65.71%
1000Mhz - 58.57%
1100Mhz - 44.28%
1150Mhz - 35.71%

and i don't really know but i would say that the best samples, which is able to use starving on 1150Mhz, would be maybe 20-25%, it would be appreciated if all who reached 1150 tell me if they were able to use starving on it, thanks all, i am just a curious dude :D

Re: Your N900 Maximum Overclock
 

Started with overclocking yesterday, with hilarious results.

Background info: back in PR 1.1.1, I had an issue where the CPU would lock at 50%+ usage with no apps open. I managed to avoid the problem by eliminating practically all widgets.

Anyway, I read a few threads, jakiman's excellent guide and started with the 'ideal' profile with limits = [250, 1100].

The results were GREAT! I could finally watch Youtube, and basically any video site with absolutely no jerkiness or lag. The whole system became much more responsive and fluid.

I tested stability by about 35 minutes of non-stop web video watching. Not shockingly, this drained the battery by 15% or so, and the phone heated up (don't have the temperature module yet, but it was quite warm to the touch).

Coincidentally, I had installed the excellent 'Desktop Activity' app, and euphoric, I created a Widget Heaven profile (pretty much all the widgets that would fit in 4 screens). Satisfied with the layout, I reverted to my original desktop layout and left the phone idle. At this point, the remaining battery was 75%.

I came back to a drained phone: BatteryGraph showed the 50% CPU bug, and the steepest linear drop I've ever seen - and this must be some sort of record: the phone went through 75% of the battery in 2 hours.

My next settings to test: Starving at 1000Mhz.

Re: Your N900 Maximum Overclock
 

Mine is at 500-900 lv, but I intend to try to hit 1150 for 24/7 usage. I think my CPU is quite lazy, 'cause I can't even run default speeds (250-600) at 'ideal'.

Re: Your N900 Maximum Overclock
 

I haven't overclocked (yet), mostly because my battery already requires two charges a day (~7hours/charge). This is fine most days because I can charge off my laptop, etc.,but when I'm out on weekends it rarely lasts unless I use it sparingly.

My questions is, how has OCing affecting battery life?

Re: Your N900 Maximum Overclock
 

The theory is, it can boost your battery life, now Nokia's default kernel is 250-600MHz using 1.075-1.350V, if you used the ideal profile, it will be 500-850MHz using 0.975-1.200V, so actually, since you are using lower voltages, it will help boost your battery, not to mention since your device will be more responsive, it will do most of its processes faster so it will take less time doing them thus saving energy.

Ofc, you can go commandos with the battery saving, set the profile to XLV and enable 125Mhz (which uses 0.850), more on that stuff here:

Enjoy :D

Re: Your N900 Maximum Overclock
 

using lv 250/900, had problems with ideal 250/900

Re: Your N900 Maximum Overclock
 

I'm running my N900 @ 1GHz and I love it :) ok it becomes very warm when playing games.

Re: Your N900 Maximum Overclock
 

i wanna try this oc stuff!
would somebody help me out on what to input at xterm?
a max of 850 would be awesome.

like if would try to use this setting:
sudo kernel-config load lv
sudo kernel-config limits 250 805
sudo kernel-config save lv8
sudo kernel-config load lv8
sudo kernel-config default lv8

how do i start with it?
where do i get the LV kernel?

ive been trying to read on with threads discussing oc but i damn it, im a nooby with this thing.

Re: Your N900 Maximum Overclock
 

To O/C, download the following from the application manager:

-rootsh
-Enhanced Linux kernel for power users
-Enhanced Linux kernel for power users (settings)

Reboot, go to xterm and type this:

sudo kernel-config load ideal

This will O/C to 500-850MHz, to get back to the default clock:

sudo kernel-config load default

To overclock more:

sudo kernel-config limits XXX YYY

were XXX is your min clock and YYY is your max clock (e.g. 500 950), for more info, look at the links in my post above, cheers.

Re: Your N900 Maximum Overclock
 

Mine is 250/900 lv. Loading Ideal and everything above 900MHz reboots the phone.
But I'm pleased with it at 900.
And finally figured out how to quick change the overclocking with the QB app.
Love the community and finding solutions almost to anything :D

Re: Your N900 Maximum Overclock
 

yea dude from above me!
this sh*t is awesome.
just good stuff!!
aright imma go tinker.

great community guys!

Re: Your N900 Maximum Overclock
 

jus went till 500-900
tried 1000 but too battery consuming
current is using default kernel from titans
freq 500 - 805
500:33,360

Re: Your N900 Maximum Overclock
 

Mine is 250/1100 lv everything runs super smooth with no issues when multitasking. I want to try 250/1100 starving to see how that does. You gotta love the Maemo community for all their hard work!

Re: Your N900 Maximum Overclock
 

Overclocking can be very simple. Or it can get pretty complicated. For you and other n00bs who may be reading this, I'll lay out the basics again in this thread, and in the simplest terms I can. Just follow these steps:

1. Using the App Manager, install these packages:

rootsh
Enhanced Linux kernel for power users
Enhanced Linux kernel for power users (settings)

The Enhanced kernel will allow you to set various clock speeds, voltage profiles (like 'ideal' 'ulv' or 'lv') and many other parameters.

2. The phone will need to reboot to install the new kernel. It should restart perfectly normally.

3. Open the terminal app and type:

sudo gainroot

Hit enter. The prompt will change from '$' to '#' meaning you now have root (administrator) privileges, so be careful!

4. Type this command:

kernel-config limits 250 750

You should get a confirmation that the specified setup has been loaded. Close the terminal.

5. Congratulations! You have just overclocked from 600Mhz to 750Mhz!

If you have no problems running at 750Mhz, you can re-run the kernel-config command and increase speed as to much as 1.15Ghz, but some units will not tolerate max speeds. To stay on the safe side, I'd recommend a max of around 850Mhz.

6. To set lower voltages type (for example):

kernel-config load ideal

The 'ideal' profile is fairly severe. If you have problems with videos or anything, try loading a more conservative profile like 'lv'.

7. To save your entire configuration so it can be reloaded with a single command, type:

kernel-config save <name>

You can then reload your saved configuration with:

kernel-config load <name>

If you reboot the phone, as a safety feature it will by default return to the standard 600Mhz and voltages, etc. You need to re-run the kernel-config command to overclock again.

8. I do not recommend using the command:

kernel-config default <name>

This makes you custom configuration the default settings, even after a reboot. Sounds good...but if your phone becomes unstable and keeps rebooting, it will keep loading an unstable configuration. Better to run a command or two after a reboot or setup Queen Bee or something to make loading configurations even easier.

I actually run my phone with a totally stock configuration except for a 850Mhz overclock. But as I said, many other options besides clock speed and voltage can be specified using Titan's enhanced kernel. For more details check these out:

Re: Your N900 Maximum Overclock
 

alright!
so now im oc'd by min 500 max 850 and everythings prerty dam stable.

what i would want to know now is, if i would want to use Desktop Execution widget for switching to oc and default at the comfort of my desktop.
should i just type ''sudo kernel-config load ideal'' in the command input box directly in settings?

cause id just want 2 buttons on my desktop for oc and default kernel

Re: Your N900 Maximum Overclock
 

I'm using 250-900 with ideal. At 950 strange stuff starts to happen.

Haven't tried other voltage profiles.

Re: Your N900 Maximum Overclock
 

I have been using Queen Beecon to overclock and have it set to load automatically upon startup. This is a nice feature because it will boot in the default frequency but then OC it to 850 (im using ideal) as soon as hildon loads.

My n900 has never reboot once (knock on wood). I use 1.1 ghz pretty frequently for gaming, although it does kill the battery and cause the device to get rather warm.

Re: Your N900 Maximum Overclock
 

That command would only load the 'ideal' voltage profile, no change to clock speed.

Read through my post above (#35). Setup a stable speed and voltage profile you like and run the 'kernel-config save <name>' command. Then put 'sudo kernel-config load <name>' in the widget command to load all your settings at once.

Just to be clear...you do not now have 2 kernels installed. You have only Titan's enhanced power user's kernel, which can run custom or default (stock) settings.

Thanks for uploading the image stas123.

I see this battery graph everyday :) with streaming music on.

Re: Your N900 Maximum Overclock
 

ok so here's what i did.

installed the linux custom kernel for power users and then the linux custom kernel settings..rebooted, proceeded to xterm, typed in ''sudo kernel-config load ideal''
so there im oc'd to min 500 max 850.
and then changed it to min 250 max 950 by putting in
''sudo kernel-config limits 250 950'' and saved it with the name ideal950. (ill only use oc when watching videos online)

now i made 2 desktop execution widgets with the command for loading ideal950 and the default kernel.

im proud of myself, god damnit thank you people!!


EDIT:
meh..youtube keeps reloading when im trying to watch.
ok so i have more figuring out to do. gotta see which settings will fit.

Lates!
