    Is this the right type of RAM for the new 2013 27-inch iMac? I want to take the default bare minimum that it shipped with out of the iMac and replace it with 4 sticks of this.

    Thanks.

    Yep. The specs on Apple's support site confirm what DeltaMac said.

    http://support.apple.com/kb/SP688

    "8GB (two 4GB) of 1600MHz DDR3 memory; four user-accessible SO-DIMM slots. Configurable to 16GB or 32GB."

    Yes, that is the 8GB package of the same modules in this 16GB package which I have been using it in my Late 2013 iMac alongside 16GB of stock Apple Elpida for the past 3 months flawlessly.

    Actually, Apple's specs on the Late 2013 iMac are incorrect. The Haswell iMacs require 1.35V DDR3L, not 1.5V DDR3. The Crucial is the lower voltage DDR3L.

    Thanks for the help everyone.

    Does anything need to be done software/OS wise after installing the RAM or is the iMac good to go after installing the sticks and rebooting it?

    Thanks!

    1.5v actually does work. I have confirmed it on quite a few 2012 or 2013 iMacs as well as other Apple machines that ship with 1.35v RAM. The thing is you can't mix the 1.5v and 1.35v RAM.

    Actually, the problems with 1.5V RAM most often manifest when 32GB is installed. With less than 32GB you are far less likely to see the kernel panics/crashes.

    All Late 2013 iMacs ship with 1.35V DDR3L.
