I've read a number of the threads here about memory in the 2020 27" iMac (dual vs single channel, mixing brands and/or size modules resulting in lower clock speeds, etc.).
I want to equip my new iMac with 64 GB, and was originally thinking of getting 2 x 32GB and putting the stock 8GB in the other two slots, for a total of 72GB (and giving me the ability to easily increase the RAM later, if desired), but then I read about the lower clock speeds. But if only populate two slots (2 x 32GB), then I'm running single rather than dual channel, which led me to rethink the whole thing and perhaps get 4x16GB (which is a bit cheaper, anyway).
Are these differences noticeable in the real world, or are they small enough so that it doesn't much matter how I do this?
