    Just purchased my 27" iMac and I am now looking at purchasing ram. Best as I can tell, this is what is needed:

    1600 MHz (PC3 12800) DDR3L SDRAM SO-DIMM​

    Does any know the CAS latency? and what is your most trusted brand for memory

    Is it possible to order 2x8GB to have 24GB? Would there be any issues with this configuration?

    Ivy Bridge processors work best with dual channel memory, means you should have two or four banks of equal sized memory, e.g. 2x8GB, 4x4, 2x4+2x8...

    Seems like it will be the same memory (27" at least) as the 2012 MBP.
