Sorry guys, I came from Win Moibile devices and the guys over at XDA pretty much liked pushing the boundries of devices they had.
The vast majority of custom firmwares are better than the manufaturers by a mile and they have overclocked devices successfully.
IF you read my original post i was asking for comments, not possible would have sufficed.
Strange that other devices have successfully been tweeked and clocked to improve performance and that this device apparantly cant run over 600MHZ or it will fry. Granted i probably posted in the wrong section but guys, seriously..... You guys are acting like we are in the 1800's and im suggesting bulding a machine called a helicopter that can hover. Yep, impossible... go away nutter
In general I do not like all kind of people here who rigorously try to put boundaries on ideas because of their point of morality / satisfaction (e.g. 'it is fast enough', 'it is better not to') as long as the people who intend to break this limits are aware of the risk and outcome. The thread starter seems to be more than aware.

The link claims OMAP3430 @ 600MHz as well? If devices come clocked by the manufacturer above 600MHz, that would be interesting to me.
I'm not claiming that you can't overclock the omap3430, just that it's not supposed to be clocked above 600MHz.

@C0rt3x: Okay, we've seen the screenshot the first time around, but how is it relevant ? Listing the CPU as an ARM9 does not help it's credibility either.

CPU itself has really only some effect on the total use-time. Display eats most of the power, cellmo is eating a lot with network traffic. Having higher speeds usually allows cpu to go back to idle sooner, so, indeed, it might even prolong the battery life if you overclock the CPU. Having said that, I don't especially suggest anybody to do it. I can only say that I have seen it running at 650, so within the suggested 10%.
Race-to-idle will only be effective in increasing battery life if the only CPU usage they're getting is in short bursts. Any prolonged low-level usage will quickly eat up battery at 600MHz (music playback where things would happily run at 250MHz is a good example).
Either way, I'd say not making yourself a $600 brick is top priority here.

I don't know enough about the gritty details, but on the Summit, at the OMAP3 power presentation Igor Stoppa (and he's no n00b when it comes to Maemo HW) very explicitly said - please don't overclock it - it WILL fry.

If the processor runs @ 600MHz max, the device must accept that the processor could run @ 600MHz all the time without frying, otherwise it should have been underclocked by Nokia. Imagine you buy an i7 @ 3Ghz, and Intel says : be sure to not peg the cpu at 100% more than a few seconds, else it can fry...

. Also, we have thermal monitoring and CPU governors so, if done right, you should not be able to fry your device in real life, UNLESS you ignore all the failsafes and use it in a way not meant by the manufacturer (and that's what overclocks and manually pegged full speed are). That's what I understood the warning was supposed to mean.
