    Hi, I'm not (yet) an owner, but I'm wondering about the possibility of overclock on the new Intel Core (2) Duo iMacs. Has anyone attempted this yet? I did a quick google search and only came up with people OCing the ATI X1600.

    Thanks, but I'm interested in overclocking the CPU not the GPU.

    Well this might work but i don't think it supports the chipset in the iMac. Other than this there is no program i know of to overclock the CPU. There are ways but they involve hacking the firmware and you really don't want to do that. Plus no one has actually released what changes you have to make so you'd have to figure it out for yourself.

    MacAddict usually has articles about this kind of thing, and there's a forum there as well so it might be worth your while to check that out.

    Having said that, I'm not sure the speed bump you'd get is really worth the effort. Overclocking from 1.5Ghz to 1.66Ghz (for example) isn't likely to give you a noticeable boost, and getting an iMac apart is, well, a b*tch. I think, however, that the Intel processor in the iMac is socketed and not soldered, and IMHO if you're really looking to enhance your clock speed you'd be better off spending the money for a core duo processor, which I think (that word again) can be dropped right into a core single socket with no firmware modification. They aren't that expensive and a price drop is expected soon, so you might think about that instead...

    just my opinion

    One of the great joys of the intel iMacs is their near-silence. Overclocking for a 5% speed bump and a 50% increase in noise IMO would not be worth it, and would void the warranty anyway.

    you could always set your A/C to 55 degrees Fahrenheit and voila, no more noise :D

    side note: intel said the quad cores show a 70% improvement over the core 2 duos (maybe no need to OC anything in the near future)

    I wouldn't trust that crowd as far as i could throw them. Speedit was promised to be out ages ago but it is still barely working. They actually charged people for an "imminent version" about 2 months ago and the people are still waiting. They also deleted all the bad forum posts people posted about the lack of an actual version.

    As for overclocking... they said they could do it (they were the people i mentioned earlier) but they never actually proved it nor added the ability into the available versions of speedit.
