Installation is very simple: install the package kernel-flasher-maemo (section system in HAM) und reboot. There's no need for reflashing etc.

The default limit is at stable 600MHz. This is the same setting as the stock kernel and is safe.

This kernel makes it possible dynamically change the maximum frequency up to 1.2GHz (supported frequencies are 250,500,550,600,700,750,800,850,900,950,1000,1100, 1200MHz)
Warning: Overclocking may damage your device and is at your own risk!
You can manually increase the limit until your device fries using, e.g. for 600MHz
Code:
echo 600000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
To permanently fix the limit edit /etc/pmconfig.
Unlike the other kernels in this thread it can also more of use the intermediate frequencies which might be the reason why it is stable for me at 1GHz.

Apart from overclocking, this kernel has a lot of other features
(2.8.26.10, PR1.2 patches etc) see http://talk.maemo.org/showthread.php?t=43420
It also retains the version info in Settings -> Product info.
If it works well for you, please vote at
http://maemo.org/packages/package_in....6.28-maemo19/

Good luck!
run some apps that are cpu intensive with 1ghz please and tell us how hot the device is getting after 10-15mins also maybe battery report

1. If you break the device, you cant flash stock kernel back in.
2. At nokia service they will see that your using non-stock kernel and then figure out its an OC kernel one
2b. At which point they will just send the device back along with a propable bill for wasting their time with a device you broke yourself!
3. Its not right thing to do. Say I buy a new car, then I put in my own tuning fuels and oils, which make the car go faster for a moment but then engine breaks. Do you think it goes to warranty?

So there you have it. I didnt write the warranty void texts there just for fun! People... THINK before you flash any of these in your device.
While I agree with your post, I dont really understand why there are so much emotions about this whole OC business ... I mean, you wrote that disclaimer, clearly stating its everybodys risk to use custom kernels, right? From that moment on, its their desicion and ... thats it. If I fry my device using GHz kernel during a hot summer (example) ... well ... me be dumbass, me no phone, me no do again ...

that's up to brave volunteers who want to fry their device. I don't want to take that risk.
I used it for webbrowsing and other < 100% stuff.

been running 950mhz with 500dsp for a while now and my n900 seems to run really smooth even under heavy load

i would love to try a 1ghz kernel and fry my n900 some more all in the name of tech of course :-)

i love messing about with tech and running experiments on stuff so if anyone can help me getting a 1ghz 500 dsp kernel it would be very much appreciated

hint hint lehto or anyone else that can help me out

pm me if you can help i fully understand the risks etc

thanks in advance

mine @ 900mhz psx4all was using 100% it got very hot after 10-15mins.

as an overlocker i know that heat is the main obstacle.

yep heat isn't good at all specially in such a small space

i would still love to try the 1ghz with 500dsp for experemental purpose though :-)

shame there isnt a proper benchmark program for the n900 showing heat rise of components etc during the benchmark

that way peeps could find a great medium between power and lifespan

When the frequency is changed does the voltage also increase? If this isn't the case then i don't see how you could fry the cpu.

It simply wont boot with the different kernal if the frequency is too high. Just like with a PC, the voltage change is what damages the cpu due to higher temps.

Or it does increase the voltage and this should be disregarded!

idea idea if the device fries..... put it in water for a few hours.. maybe boiling water.. and send it to insurance with a £25 cheque... ohh it fell in the toilet.. too bad ...

by the way, someone tried running xp as a virtual machine or something with 900mhz or similar??
whats it like??
