32GB (two 16GB) of 2666MHz DDR4 memory; four SO-DIMM slots, user accessible
Does Apple mean by this statement that the iMac 27 inch 2020 can be upgraded by the user by adding two further 16GB DDR4 memory?
Question marked as
+1 the max for a 2020 27' is 128GB

In addition it is unlikely that you will ever need or use 128GB of RAM.
A more modest upgrade like adding 2 16GB or perhaps 2 32GB module is generally adequate.
