iMac 27" 5k 2019 Memory upgrade

crwdns2934249:0crwdne2934249:0:

Can I leave the existing DIMMs that came with the system (2x4G) and add an additional 2x16G DIMMS for a total of 40G?

Do I need to place all the DIMMS in matched pairs of slots?. For example the 4G DIMMs in slots 1 & 3 and the 16G DIMMs in slots 2 & 4 or can the DIMMS go in any slots (4G DIMMs in slots 1 &2  and 16G DIMMS in slots 3&4)?
