WHAT DID WE LEARN?

Three things to know when choosing memory for the 2020 iMac 5K 8-core or 10-core:

1. If you don't fill all memory slots, putting memory modules in slots 1 and 3 (or 2 and 4) insures Dual Channel memory mode.

2. For best speed, use matching memory size (preferably same vendor).

3. Overclocked memory won't run faster than 2666MHz.
