    Let's say I have 1x 8GB 1600mhz stick of RAM installed in an early 2013 rMBP (which supports 1600mhz).

    And I install another 8GB stick that's 1333mhz.

    Will all 16GB clock down to 1333mhz or just the 8GB?

    Should work - possibly it wont - 1333 vs 1600 = no real difference

    It will work but it will clock down as ram needs to match. There is basically no price difference between the speeds just buy the 1600

    Yes it will work. It will just downclock the highest frequency ram to the spec of the lowest.

    But isn't the RAM on the rMBP soldered on and therefore can't be added after purchasing the laptop. AFAIK, you can only opt for 16GB when placing your order.

    Good call but thankfully I was just using the rMBP as an example :p

    But if you guys say I won't see any difference in 1333 or 1600mhz then I won't worry about it :)
