    two aluminum imac upgrade questions
    hello, all. i have two questions regarding the new aluminum imac.

    1) i'd like to upgrade the RAM (to 4gb) myself. i see that the system bus runs at 800mhz, but that the ram included is clocked at 667. i'd like to know if i should stick with 667mhz RAM when upgrading or if i should go for 800mhz. would there be any advantages/disadvantages for either one?

    2) i'd also like to know whether the processor is upgradeable at all (for future reference). i recall reading somewhere that the processors on the previous generation of imacs could be upgraded (as long as one could get through the arduous disassembly of the case). i tried to look at the disassembly pictures of the aluminum imac but couldn't tell whether the chip was removable or not.

    anyway, any help regarding these two questions would be much appreciated.

    thanks!

    1) I'm not 100% sure. Someone else might have some input.
    2) Soldered on the board IIRC.

    1) 667Mhz is the RAM that is supported. You can't put in 800Mhz. Might be possible, but it will downclock to 667Mhz.
    2) Why would you want to upgrade it? The system is built around those specs and is built that way, and runs perfectly. You put in a new chip, and everything will go wonky...

    Specs:
    17 inch 2 GHz C2D imac (5,1) with 3GB DDR2 RAM, X1600 (128MB memory) GPU - OSX 10.6.3
    1. From what I've heard the differences between the two in terms of noticeable output by the user is minimal at best. Maybe in the future the 800mhz one might be more utilised in the future. But by then a new mac might be an option. And price wise the 667mhz one is much cheaper so I'd go for that. But I'd like to hear others input on this topic too.

    2. As far as I know it's not upgradeable at all. Like the above poster said it's soldered onto the main logic board.

    It will not recognise anything over 667.

    The difference between 800 and 667 is very small, but the price difference is very large.

    I paid $40 for Kingston Ram 800mhz 2x2gb sticks. I put it in my iMac 24" 2.8
    Check your about this mac memory section, or check the original box sticker for speed rating. 667 is for the 2007 model, and 800 is for the early-present 2008 model. Try downloading and usign Crucial.com 's handy memory checker. It should tell you without a doubt the max/fastest ram your capable of running in your imac.
