I bought this in early 2007, it's 2 CPUS (2cores each) making it a quadcore machine... i was wondering if i could upgrade the CPUs. woodcrest made 3.0ghz processors, but unsure if they are still just 2cores or 4 cores each

    Yes and no. The sockets are standard 771s, but the fan controller is programed for the specific chip. I don't know if there's some kind of third party update tool floating around.

    I have seen guys upgrade them to 2.66 Quad x 2, and sell them on eBay, like 3 or 4 times. When I was looking that is. So I think you just get clovertown 2.66, but I have no idea the technical skill that you may need, I have done building PCs and upgraded zifs but not Apple Intels.



    Laters...

    Does this mean that it wouldn't startup at all, or that the existing cooling may be inadequate for the newer processor?

    Have you seen the prices on these processors? You are looking at spending nearly a grand for what would probably be a negligible speed increase.

    People have done it and it works. It doesn't make any economic sense, though, compared to just reselling the old machine and buying a new one. The absurd resale prices on Macs work in your favor here.

    AFAIK the fan controller is programmed to spin the fans as necessary based on heat generation, not keyed to a specific chip. As long as the chips are within the heat envelope of the *hottest* chips apple marketed on that model you should be golden, and even if they ran slightly hotter I wouldn't worry about it....
