Refurb DDR4 PC21300 2666MHz SODIMM 8GB Kit - (2 x 4GB)
These are 2 matched previously used 4GB DDR4 PC21300 2666MHz SODIMM RAM modules, suitable for most Apple iMac models released in 2019 and 2020, and the Mac mini 2018.
This is a cheap way of adding an extra 8GB to a 27in iMac 2019 or 2020 - these were mostly sold with 2 empty RAM slots. Unless you are replacing failed RAM, they are not useful for the 21.5in iMacs or Mac mini - these models only have 2 RAM slots, and these will both be already filled with modules of the same or larger size than these 4GB ones.
RAM is an excellent item to buy used, since it doesn't degrade with age and has an extremely low failure rate.
Note: The speed of this RAM may be reported as either 2666MHz or 2667MHz - there is no difference, it is just how different operating systems choose to display them.
