Just bought this new 27' iMac i7 model 12.2 mic 2011, I LOVE IT! but I need more memory. Apple says the max is 16g but OWC (Other World Computing) says it can use 32g ? is it only using 4g on each stick or is it as the specs say with this processor capble of utilizing 32g? I trust Apple but I am a little confused. Also Cnet has an article also saying the machine can handle 32g ? Also read some comments on Cnet saying that after market vendors recieve "loose" parts to build on from the manufacturer and do not pass certain testing processes in some cases; and we should only buy the same memory as Apple has installed? Any help would be greatly appreciated!

iMac, Mac OS X (10.7.4), 27' i7 model 12.2

    As far as I know, the CURRENT iMac can handle up to 32 Gigs of RAM/Memory... 8 Gigs per ram slot.


    I personally use OWC memory on my iMac and can tell you with all sincerity that it works GREAT.


    Upgrading the memory on an Apple computer yourself, will NOT void the warranty.





    The following was posted by another user in another similar discussion...         





    OWC and Crucial have discovered the 2010 and 2011 27" iMacs will support up to 32GB of RAM. Apple only sells up to 16GB because that is all they officially support. Both OWC and Crucial are trusted vendors so you can buy from them with confidence. If you decide to only get 16GB DO NOT buy it from Apple, you can buy the RAM for significantly less from either OWC or Crucial, install it in 10 minutes or less and have no affect on the warranty. If you decided to upgrade to 32GB each of the 4 slots will have a 8GB DIMM and if upgrade to 16GB each slot will have a 4GB DIMM installed.
