Using titan's new kernel, even 550mhz uses less voltage than stock Nokia kernel did at 250mhz. The word overclocking seems to cause bad vibes. We are running the cpu more efficiently and cooler than Nokia's stock kernel ever did. So please, do your homework before swearing at the 'overclockers'. Not everyone is dumb and overclocking is nothing new. That Nokia engineer dude actually said frequency is not the problem. It's the high voltages that Nokia's stock kernel uses. My cpu right now uses less voltage at 950mhz than what your non overclocked cpu uses at 600mhz. Nokia is the one actually overclocking the cpu by over volting the cpu heavily from 550mhz onwards. I'll bet my cpu runs much cooler with less stress at 850mhz than stock N900 at 600mhz.
