Ok so i got my n900 2nd hand but clean. i had no idea on how to use it. the phone was pretty laggy (REALLLY LAGGY) but i tough it was because it had lots of stuff in it. did that nothing happen. i tough it was maemo that was slow, so after awhile i guess that was the reason everybody overclocked their device. it was running really good but i always had to run it to 1500mhz to have stable. One night i came back home, my phone tells me I have a new update. it was for the whole overclock package... I did it and it failed to do one of them. I panicked i restarted the phone.. stuck on tthe nokia logo.. almost wanted to trow my phone on the wall. FML. Then i decided it was time for a nice flash. did it and BAAAAAMMMM the phone is so stable no lag running as fast as it was running 1500mhz ( i dont know how fast that is on your n900 but on my it was stable.) I don't need to overclock and while im writing this im installing nitdroid. i love my n900

Moral of the story - if **** is laggy, overclock is probably not the solution - reflashing is.

Reflashing is always the solution. Especially if the phone comes to you second hand. (I was lucky with my second-hand one - the user seems to have reflashed the rootfs before selling it - though he forgot to clear out his settings, so for a while I had the ability to log into his facebook account - I didn't use that ability, just thought it was funny.)

But back to your story - this is why people need to learn that the number one cause of slowness in the long term on the N900 is random crap clogging it up. If you have a slow N900, always turn to reflash before overclocking.

Overclocking will make things even better afterwords, but it's not the first order solution. What annoys me is this has been common sense and publically known for a while.

Also: Stable does not mean what you think it means. Stable means generally without bugs or serious issues, and especially in regards to over-clocking, it means ****-doesn't-crash.

If everything was slow or unusable at lower clocks (how did you even get it to 1.5 GHz? I don't think the current Power Kernel supports that), but it wasn't crashing/rebooting because of processor glitches, then it WAS stable. It's only when you get above a clock speed your processor can take that you get into 'unstable' territory.

At any rate, glad things worked out for you.

i had it running between 1100mhz ~1500mhz no problem. It does support it. I had no idea how this phone works when i first got it. i tough it was like my n95 that you can re flash with no problem.
