In a sense, the CPU is already overclocked at 600Mhz.

Thank you very much for the info.
BTW Im looking forward to seeing some overclocking utility, no matter the risks ... I'll stay in touch with this thread!

Unless you did some crazy overclocking and totally overheat the CPU by burning it in. That won't be easy to do anyways as the phone most likely will crash or cpu will clock down way before that happens.

I'm not sure why would one want to overclock it?
The overclocking margin is anyway so small it hardly makes a noticeable difference in everyday use. You could get a little more throughput, but that would have meaning mostly if you use it as a rendering server or something..
My guess is, tweaking the power saving options would be more fruitful, if it's the (perceived) speed you're after.

Uh, yeah, the N900 battery life is crappy enough as it is, overclocking is a good way to shorten the battery and the life of the unit.

What would run hotter at such utilization?
66% @ 800Mhz or 100% @ 600Mhz
If it can handle 800Mhz, it might even run cooler.
All depends on the sample quality in your N900.
Overclocking does not mean we will constantly use that faster frequency at 100%.
It's the "instant" cpu power that it lacks sometimes.
When it shoots to 100% @ 600Mhz which it does frequently during certain operations, it's hitting a bottleneck.
Instead, if the cpu was capable of 800Mhz for its ceiling.
Then maybe it might only neded 80% at 800Mhz for that "instant".
Why do we have quad cores in our desktop pc's when 90% of the users will never really get it to use 100% on all 4 cores?
The more speed headroom you have, the smoother it can run even for little non-cpu intensive tasks.
Well, I love my N900. So it's natural to want it a bit faster.
- less video playback frame drops
- less pauses during music playback while multi-tasking
- less frame drops in game emulators
- smoother multi-tasking in general
I wish you can increase the RAM it has to 512MB. That would actually make it a lot smoother during multi-tasking. But we know that's really impossible. So we are clutching on straws here to at least bump the cpu a bit faster.

I absolutely agree!

At least that's what I gather from the desktop PC overclock/cpu throttling experiments I've made. But who knows, N900 is a bit different beast, so I guess we'll just have to wait and see until someone actually tries it.

I would be interested in overclocking the n900 just for the fun of it, it may not be entirely necessary, but if its a risk many of us are willing to take, then why not?
I don't get why people here are slamming the idea. No one is forcing you to overclock your n900, those who do want to do it obviously understand the risks.

Not slamming anything here, just having a lot of doubts
