    I was wondering, what brand memory comes with the iMac? What is the max size? Apple only offers up to 1GB (512x2). Is it possible to put a single 1GB stick in the user accessable slot (in addition to the stock 512MB that came with my iMac)??

    TIA

    First thing: Don't buy RAM from Apple.

    Next, congrats on getting a new iMac. I assume it ships with 256 MB like most of Apple's new machines, so I'd recommend just buying a 512 MB module. 768 is great in most machines.

    Don't worry about the RAM brand, just buy the correct type of RAM (most sites make it really easy to figure out). I got some RAM from Crucial recently and it was well-priced and I've had no complaints.

    Edit: Stock 512? If you've already got that much, just stick in another 512.

    I ordered the iMac with 1 stick of 512MB, to max out the internal slot. (Dont want to open this thing up down the road) I actually have another 512MB and a 1GB available, but just wonder if the 1GB is supported in the user accessable slot?

    Thanks!

    640 is for most apps. the only things that max out my ram is video editing on iMovie, and i was only using that just to see what it was. i dont usually use iMovie. so yeah 640 is more than enough for most users.

    1GB in the user slot can be done on some of the models. Pay attention to the specs and buy quality RAM. Some offer a 1GB module just for the iMac.

    All,

    I have the 1Ghz 17" iMac (Feb 2003 model). Apple says that this iMac must use PC2100 SO-DIMMs in the user slot.

    The iMacs released on 9/8/2003 can use PC2700.

    So, I went to OWC's site and ordered:

    512MB PC2100 DDR 266MHz 200 Pin Low-Profile 1.25" BGA Memory Upgrade for Apple iMac G4/1GHz 17" model, all PowerBook G4 12" Models, all iBook G4 Models. New, Lifetime Advance Replacement Warranty. (OWC2100DDRSO512)


    I got the part yesterday and while the front has a sticker that says OWC2100DDRSO512, the back of the chip has 2 stickers that say this is PC2700. I put the chip in and the iMac did boot up fine and seems to be working fine. System Profiler shows this is PC2700 RAM.

    So, is this OK? Is this chip just dropping down in speed? Can this lead to any problems in the future? Will my system be stable with this RAM?

    I'm going to call OWC today and see what the deal is.
