Can I use three 8GB memory chips in a 14.2 IMac 27"?
I want to upgrade the RAM in my iMac 14.2 27" from 2014. I have 4 slots, with one 8Gb chip right now. If I get a 16Gb set of two, can I use all three for a total od 24GB?

That should be fine; see these instructions here (although they do say that matching RAM//slots is best):

And, make sure they are the right specs - buying from OWC (macsales.com) or Crucial is most recommended.
