    The Risks of Overclocking

    Not so sure this should go in Hardstuff, feel free to move it .

    I'm always hearing about how bad overclocking is for your computer but I have never seen any evidence to back this up. Does anyone have any explosive experiences that they can share?
    With love and many thanks,

    Well BlindMelon7 overclockignc an be dangerous if you dont know what you are doing. Years ago i had an Athlon XP 1700+ and i decided to overclock it. I didnt know much about overclocking and i pushed it too far and blew the chip it never worked again

    The best thing to do if your new is read some guides on xtremesystem forums etc. Make sure your computer has good airflow too.

    It is also said that when you overclock the likes of your cpu etc that you shorten the life of this cpu. But i have found that even if its life is shortened you will have changed it several times and as such it wouldnt affect you.

    So like i said. Read up and give it a go. Hardware is alot more overclocking freidnly today than it used to be.

    I had a friend that installed a watercooling system just to overclock. The seal broke on the block and the water fried his system. Other than that I knew someone else that managed to overclock a Celeron quite a bit when they were running at around the 500 Mhz mark.

    He put it onto one of the upright boards that went into the slot the P3's used and attached a fan to each side of it, also installed extra interior fans. Managed to get another 300 Mhz out of it and it ran pretty cool without any probs!

    This is a genuine question not a dig or anything but...

    is overclocking really worth it? I mean, is the difference that noticable?

    Depends on application, wont make your Word run any faster, but noticeable improvements in games, or benchmarking. Every mhz squeezed out of the gfx is worth it IMO

    it can be worth it, when I overclocked my x800 pro from 420 core/450 mem to 530/580 it meant I could play games with alot higher resolution

    If you do sane overclocking (no extreme cooling or voltage hikes) then the worst you're going to do is shorten the life of the CPU. If it dies within a few months it was probably not going to last all that long anyway. Usually they'll live overclocked beyond their usefulness anyway.

    Now when it gets extreme... well it can all go wrong then!

    It depends.
    Voltage is the killer of chips, not raw MHz. You can try to make a chip run faster than default, and without any additional voltage, the worst that will happen is "bad maths" (ie. the calculations the CPU does are wrong).
    When you add additional voltage, you are increasing the risk / speed of Electromigration. See http://en.wikipedia.org/wiki/Electromigration

    Of course, this will only kick in at certain points. Both AMD and Intel have simply raised a CPU's default voltage to get more clock cycles out of a design. This is what overclockers basically do in their bedroom
    The issue is finding the safe point of voltage and life of the chip, but with the rate that CPU’s develop, it’s almost not a worry anymore. No one cares if a CPU dies a year sooner – provided it has lasted a few years in the first place, it will cost little to replace / upgrade.
    I think it goes without saying that giving the CPU a big dose of voltage, without the correct cooling can lead to its death

    Heat shortens chip life too, and when you increase the clock without increasing the voltage, you still increase the heat output.

    I heard overclocking could send you blind..

    Indeed. But its *very* hard to get a chip overclocked that much, without any extra voltage that this would be an issue.
    The heat produced by more Mhz is little compared to adding voltage

    Well, I think basically is if you can't afford to buy a new one dont overclock. I think non overclocked processors run smooth enough for high end games for example a core 2 duo e6600.
    Overclocking are for enthusiasts. That's what i think.

    The worst I've done is gone too far and not been able to push it as hard again. I'm guessing this would happen after a few months anyway.
