    I just ordered a refurb iMac 5K and would like to upgrade the RAM. Does anyone know if Corsair Mac Memory CMSA16GX3M2A1600C11 is compatible with the iMac 5K (Late 2015)? I've found it listed to be compatible with the Early 2015 models, but no confirmation for Late 2015. Any insight would be great, thanks!

    It'll work, but at a slightly slower speed than the stock RAM (1600 MHz instead of 1867 MHz).

    I'm interested to know what the implications is for the slightly slower ram mixed in with faster ram? Would we expect any noticeable performance issues?

    There is plenty of 1867 Ram out there for a good price. You can pick up 2 4GB sticks for less than $50 for total of 16GB or get 2 8GB stick for under $100 and have 24GB total.

    Why mix the speed of the Ram if your buying for the first time? Your Apple ram will run at the lower frequency if you put that in. If it's something you already have or its FREE, then go ahead but if your buying it, get the same speed makes the most sense.

    I totally missed the speed difference of the RAM. I'll stick with the faster RAM, thanks!
