Hopefully I can resolve my questions as I've been getting conflicting info.  I want to upgrade to the max memory and need to know how much and what type of memory sticks I need. Also, a recommendation of where to buy it would be helpful. 

 

Memory installed is:

Memory  8 GB 1333 MHz DDR3

 

System report:

Model Name:          iMac

  Model Identifier:          iMac12,2

  Processor Name:          Intel Core i5

  Processor Speed:          2.7 GHz

  Number of Processors:          1

  Total Number of Cores:          4

  L2 Cache (per Core):          256 KB

  L3 Cache:          6 MB

  Memory:          8 GB

  Boot ROM Version:          IM121.0047.B1F

  SMC Version (system):          1.72f2

 

Thank you.

    From my time on this Forum the two equally endorsed vendors are Crucial and OWC. The both carry and gaurentee compatability with their memory upgrades. They also have the 8GB sticks.

    Check with the Mac specialists at Crucial and OWC...they offer memory upgrade kits that they guarantee to be compatible and often larger than what Apple says it supports as the limit.

    There are a lot of mixed feelings about this since OWC offers higher memory on several Apple machines than Apple officially supports.  Plus they guarantee the memory and will take it back if there are problems.  The down side is if you need warranty service you have to replace the memory with the original to get Apple to service the machine.

     

    This becomes a matter of call for the user, do you go beyond the stated limit or not?  What is your comfort level?
