Mid-2017 saw the introduction of two 21.5" iMac model lines (which is unusual). They have somewhat different RAM specifications.


The OP seems to have the non-Retina model (iMac 18,1). The Retina 4K model had model identifier 18,2, could accept twice as much RAM (32 GB / 64 GB), and required faster RAM. On both, the RAM sockets are sealed in (non-user-accessible).


Other World Computing groups both model lines together, with the note that the 64 GB kit is for the "iMac18,2" (that is, the Retina 4K model) only.
