    Hi All!

    I have an iMac mid 2011, with the following specs:
    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: 4 GB

    I currently have 2x2GB memory dimms on BANK0 and BANK1 (DIMM0).
    Will it work if I install 2x4GB on the empty slots (DIMM1) and end up with 12GB?

    Thank you for your help!

    Yes! I think in the 2011 you can only have 16gb which means a max of 4gb in each slot.

    That's how my 2010 was setup. Oddly enough one of my two 2gb sticks failed causing restarts and kernel panics so I just bought matching 4gb to bump it up to 16gb.

    Yep, adding an extra 2x4GB for 12GB total will work fine, many people have done it before and I plan to do it myself.

    That was initially true when the 2011 iMac was released but since then 8GB sticks started to be made. 2011 iMacs can have a maximum of 32GB RAM.

    I'm running 32 GB RAM in mine no problem. The answer to the original poster's question is yes, it will work.
