In this demonstration I talk about which ram to install on the 2019 27 inch iMac.
The most important thing when purchasing the Ram is to make sure that you select the right specification.
You will need 2x sticks of Ram of equal specification so that you can get them to run in dual channel mode.
I purchased 2X Crucial 16GB
DDR4-2666 SO DIMM
CT16G4SFD8266

You could also consider filling all slots with equal Ram modules for example (4x4GB = 16GB) or (4x8GB=32GB), (4x16GB = 64GB) in total.
As I mention in the video I Have tried installing it along side the 2X4GB modules and also replacing the 2x4gb modules.
I even tested installing just one 16GB module.
Results discussed in the video.
