    I plan on buying a new iMac. I want to upgrade the RAM, but I don't want to pay Apple's prices. (Looks like they charge 3x what its worth.)

    So I plan to buy RAM from a third party. But I've been warned to consider dual channel memory support. So first, does anybody know definitively if the iMac supports dual channel memory? I have found conflicting information on the subject and no authoritative documents.

    If so, does anybody know which RAM I can buy from a 3rd party that will match up with Apple's default 1GB stick? I'm told, but not sure if it's true, that I should look for a stick that is the same size (1GB), same type (PC2-5300), and has the same number of chips on the stick. This last one seems strange to me and I'm not sure how I would go about verifying this one before I buy anything.

    Also, is there a way to know if dual channel mode is active (preferably within OS X).

    The benefit of dual channel is minimal since you have dedicated video cards.
