    Default is this real abt overclocking?

    i read this when i googling to overclock my phne.
    is it real?

    "Your device lifetime will half by each 100mhz increase in clock speed. So if it works 50 000hours @ 600mhz, it only works 25 000hours @ 700mhz, 12 500hours @ 800mhz, ETC"

    any expert cn explain this?
    since i already overclocked my phone to 850mhz,means my phne lifetime gnna b 1year n half.
    nooo..

    i don't think it's the lifetime that will decrease significantly. it will decrease to some extent but not by half. however, it will decrease your battery life that much.

    Dude you can safely overclock ARM Cortex A8 processors to speeds above 1Ghz. It even says so in the official website.

    http://www.arm.com/products/CPUs/ARM_Cortex-A8.html said:
    With the ability to scale in speed from 600MHz to greater than 1GHz, the Cortex-A8 processor can meet the requirements for power-optimized mobile devices needing operation in less than 300mW; and performance-optimized consumer applications requiring 2000 Dhrystone MIPS.

    Default Re: ARM CPU

    yes, of course you can 'clock the cpu... BUT if you know PC overclocking, the real problem is whether the other bits will withstand the 'strain'...

    It is easy to do on the PC, by adding extra cooling, better ram chips with heatsinks on, better GPU with bigger fan, heatsinks on other bits etc.....

    now try this with the N900....

    Dude overclocking is completely different on a mobile. Unlike a PC in a mobile the system clock is generated by dividing the master clock with a frequency divider while in a PC the system clock is generated by multiplying the master clock with a frequency multiplier. And the frequency of the master clock in a phone is the highest stable frequency the phone can withstand properly. So even when you overclock a mobile extra cooling is not needed. I hope now you understand.

    Ha, if you overclock to say 800Mhz, you won't notice a significant decrease in lifetime. You'd be through a phone or two after the N900 before it'd die. Gotta remember, the A8 was made to run from about 600Mhz to 1,000Mhz, so overclocking to say 800 or 900Mhz, you're not even truly "over"clocking.

    There is no way to truely overclock a mobile phone. Only PC's can be truely overclocked as i had said in my previous post mobile phones lack frequency multipliers.

    You can overclock Android phones at kernel level
    See DeFrost Desire ROM for example
