    I have a 27 inch mid 2010 IMac with the 2.93 I7 processor, model identifier is iMac11,3. Current memory is 4x2 GB sticks and it's not enough.

    I've called OWC - they claim I can put in 32 GB.
    Called Crucial - they claim I can put in 16 GB.

    Someone here must have one of these things and have done this. How much can I put in?

    Is OWC or Crucial better in some way?

    I found this Crucial 16 GB kit from Amazon, it says "notebook" in the description but I believe it will work in my iMac. Is this the memory to get?

    Crucial 16GB Kit (8GBx2) DDR3L 1333 MT/s (PC3-10600) CL9 SODIMM 204-Pin 1.35V/1.5V Notebook Memory Modules For Mac CT2C8G3S1339M

    Lastly, if I purchase the above kit, and want to leave in 2 of my current 2 GB sticks - which slots should this be put into?

    thanks...

    Your Mac supports 32GB. You can find specs on all Apple products, including maximum RAM:

    Odd, you say 32 GB. When I go to that Crucial Memory Advisor you suggested it lists 16 GB as the max.
    EveryMac says 32 GB.

    This is confusing.

    Hi, running right now and running just flawlessly in my 27" iMac i7 late 2009 is
    4 x 8.0GB 1600MHz DDR3L SO-DIMM PC12800 204 Pin from OWC.
    32 GB but clocked at 1333MHz. The memory controller seems to max out at this. But I do have the feeling that the RAM is actually running at 1600MHz.
    OWC RAM works very well.....just my experience:)
