    I want to add 2x4GB DIMMS to my 2011 iMac with the standard 2x2GB DIMMS for a total of 12 GBs of memory. Does it matter which slots hold the 4GB DIMMS and which slots hold the 2GB DIMMS? For example, should I put the 4GB in the first two slots and move the 2GB DIMMS to the last two slots or just add the 4GB DIMMS to the last 2 slots and leave the 2GB DIMMS where they are.

    I just finished upgrading three 2011 iMacs using the Crucial 8MB upgrade kits. I just put the extra memory in the two open slots and everything is working great.

    As an aside, FCP X runs so much better now, I'm sorry I didn't make the upgrade sooner.

    I just upgraded my 2011 iMac with 2 new 4gb chips and put in the 2 empty slots. Turned it on and no problems what so ever. I can tell things are running faster just by opening iPhoto. Best $50 upgrade I have ever bought.
