the same nokia engineer would im sure say running @ max for long periods with default would be bad for the device. so dont play games or leave the phone ringing for long periods of time kids..... Invalid points, the owner of this thread wants to lock it @ 600, you completely went off topic what would the manufacturer of a car recommend you to and say it is safe to drive over the speed limit? blah blah, this is a stupid point! Put on a seat belt, so you don't actually sue them when you have an accident, which you would do. the phone was rushed and barely finished at release? and you are going to say that nokia got everything totally correct and right at release? That was the N97, not the N900, get your facts right why would it be stupid to clock over 600 espessially considering the voltage is lower than the upper stock freq settings??? whats worse for life of a chip? higher voltage or higher freqs? or as bad as each other? Because TI (Texas Instruments, if you can't google) actually did tests, and they recommended that the device gets clocked at 600 max, the new CPUs can be clocked to 720. Now, here's the small difference, TI is full of engineers, tmo otoh, is filled with people who'd deem something as safe since it worked for a day. "Oh yeah, 825 is a safe bet, you know, cause no phones have been fried till now, and it's not much of an increase" (it's a 37.5% increase btw) if the phone is a HUGE amount faster and more responsive but lasts half its life, it'll still last twice as long as i will own it! Fry you N900, no one gives a **** if you chose your own decision... so i'd be stupid not to clock it in my opinion! ... but don't spread BS facts, saying it's Nokia's decision to underclock it, which, you are doing right now. i guess its been stupid of me to but a cheaper processor for my pc and clock it to levels of a chip twice the price for the last 12 years. hmmm, and how many have died? Maybe because PC CPUs are actually underclocked? Again, get your facts right! don't take the limiters off of yer 50cc scooters. don't chip/map your diesels. the manufactures ALWAYS say the changing anything from their config is bad.............. And you're saying it.s good, which it isn't but hey you have your opinion and you seem stuck in that, me, i'll take the red pill. Take it on your own, don't tell people it's safe.
