My question is though, since you didn't quite grasp it was what damage can lower voltages do to the processor?

This whole thread is pervaded with FUD. There's a big official overclocking thread. Any real problems should have been reported there, and they really haven't been. There aren't any real problems. Well, maybe the battery could die early. The real solution is to have a few extra batteries anyway -- that's handy for several reasons not having anything to do with overclocking, like lots of people have gotten into situations with N900s that seem dead and they sent them back to Nokia, only to find that the only problem was a dead battery, which they could have determined in ten seconds if they had a spare.

i have my n900 oc'd at 900. for some reason or another one night i plugged it in to charge and the battery wasnt full when i woke up. looked at the battery log and it showed my phone running at full cpu load for 4 hours! i think i left something running. anyways, my phone still works fine.

So where is this main OC thread that everybody keeps mentioning? I can't find it, but I'd like to.

Having experienced this myself I know for sure that an overclocked N900 at full CPU power can prevent the battery from being charged.

For example an older 800 mA charger with the Nokia provided adapter piece is not powerful enough to keep my N900's (at 1150Mhz, fully cpu loaded) battery from draining, then eventually shutting down.

That said I am still trying hard to overclock damage the N900 but even in tropical climates that is a harder job then one might expect.
It won't even crash and up-time is 15 days (thanks to Swapolube to maintain thing smooth).
Anybody else getting bored by this kind of stable behavior of the N900?

I did that with my oem i7 cpu fan

bump. any dead N900s yet?

nopes running fine @ 1.1ghz for last 6 to 7 months.

A better question would be "anyone noticed strange, seemingly random errors or data corruption yet?" No one's N900 is going to up and die, it's just going to act stranger and stranger.

1150mhz lv since day 1 (beginning of march 2010) and its still living and behaving "normally".
