    Hi all, long time Windows user here and I'm looking for a potential switch to an all-Mac environment. I'm thinking of buying the latest iMac and a Mac Mini models. Would it be safe to assume that I can safely use my the 8GB stock iMac memory dimms to the Mac Mini and only purchase memory for the iMac? Thanks for your time.

    Mac Mini:
    "4GB (two 2GB) of 1600MHz DDR3 memory
    Configurable to 8GB or 16GB."

    The exact specs for Mac Mini memory are here:

    27" iMac:
    "8GB (two 4GB) of 1600MHz DDR3 memory; four user-accessible SO-DIMM slots
    Configurable to 16GB or 32GB."

    Based on this (incomplete) information, it looks like you can interchange memory between the 2012 (27") iMac and the 2012 Mac Mini.

    I don't think Apple will release more detailed specs for iMac until the systems start to ship. This page will probably be updated at that time:

    Note that we DON'T KNOW what kind of memory the new 21.5" iMac will use. Apple has said it's not "user serviceable"; it may be a completely nonstandard memory module, or it may be a normal module that is just hard to get to.

    These were the pages I looked at myself prior to posting and I agree it's not clear. I also should mention that I'm interested in the 27" iMac, so I guess I'll have to do some more waiting...

    Well, according to Crucial, the iMac 27" uses DDR3 PC3-12800 and recommends Part# CT3650255. The Mac Mini however uses the exact same specification DDR3 DIMMs but with a different Part# CT3650338.

    Do you believe they're really different or incompatible? Since I'm planning on buying an iMac 27", I was really hoping to save some money by using the iMac's Dimms on the Mac Mini...
