    Adding Memory to i7 iMac

    I have a question about which of the four slots to add memory. I bought i7 iMac with basic 4 GB memory configuration (2x2). I am adding 8 GB (2x4). I have read that memory that is larger should be placed in the slots occupied by original modular, then smaller modules in open slots.

    Here's is source of my confusion. Instructions that came with iMac state:
    "If you replace the installed memory modules, insert new memory module into each of the slots furthest from the display."
    This is what I did and put the smaller (original modules) in open slots -- closest to to display. However. Apple support page linked to "About This Mac" in menu bar states
    "i5 and i7 Quad Core iMac computers come with both top memory slots populated. These computers will not start up if only a single DIMM is installed in any bottom slot; these computers should operate normally with a single DIMM installed in any top slot. Core Duo iMac computers should operate normally with a single DIMM installed in any slot, top or bottom. ("Top" and "bottom" slots refer to the orientation of the slots in the pictures below. "Top" refers to the slots closest to the display; "bottom" refers to the slots closest to the stand).".
    These instructions conflict with each other. What is the correct positioning of the larger modules. The computer is starts up fine and is operating. I just want to make sure I am getting the maximum advantage of the additional memory.

    Other World Computing has a series of installation videos here:

    Oops. Never mind. They show how to do the install, but the one I watched didn't answer the question about location of memory pairs.

    If you click on the apple in top left. it will tell you the amount of memory on you computer. This will tell you if the new memory is working
