The question is per the title. I have 16gb of DDR3 1333mhz ram in a 2011 mac mini. Would this ram work in a new 5k Imac? (Inserted by itself) Would the ram work in conjunction with the 8gb DDR3 1867mhz (albeit clocked down to 1333mhz)? I would like to be able to re-use my ram (even though there would be a performance hit). Thanks for the responses.
