interesting threadi have a dell m1730 laptop that came with an overclocking application as standard 2.8 up in .2 intervals to 3.6 its a dual core processor, my laptop is crammed with stuff and doesnt have much room to breath but ive been using it overclocked at 3.2 for over 2 years and no problems,
overclocking is not that dangerous you just have to be carefull not to do anything stupid like overclock the n900 straight up to 1.5 that would fry it.
hell if some people are willing to try it why not whats life without a bit of risk
I looked through the kernel sources and didnt find anything of interest. By looking at what the android guys did I found out that our clocks arent controlled in such simple manner. Though I didnt understand much of the code in there.

thats what im saying, if overclocking is done in moderation it can be alright just keep increasing in small intervals until you find the point were the phone starts to get abnormally hot and or starts to malfunction

I'm looking forward to this! My desktop pc is oc'd from 1,6ghz to 3,1ghz and it's rock solid.
Omap3 should handle the extra 200 mhz just fine and it'd prolly be enough to make the n900 experience much smoother.

I say it is not needed. Higher CPU clock usually leads to higher power consumption and even at stock clock the battery capacities of the N900 aren't something to cheer about to say at least. Also I think there still is room for software based improvements in terms of speed and reaction, so there is no need yet to pull out the hardware-mace.

frequencies and voltages are in kernel in file
arch/arm/mach-omap2/omap3-opp.h
i was able to overclock the phone to 800Mhz, boot it without problem and using it for 5 minutes
but i am hunting longer battery life instead of speed, so i am running kernel with 125Mhz enabled
(125,250,500,550,600) instead of (250,500,550,600)

And higher clock frequenzy doesn't necessarily increase the power consumption on a mobile device as much as it does on pc.
Overclockin a device like this would only push the highest available frequency so it would consume more power, but it would do so in shorter perioids.

Say, would it be possible to boot to another maemo5 os from sd-card to check if 800-900 mhz is stable?
