Question: Upgrading Ram iMac 17,1 (Late 2015) to 24gb
I want to confirm that it's ok if I have two 4gb sticks (original RAM) in my Retina 5K, 27in, Late 2015 model iMac now, that it's ok to use the macsales (OWC) RAM to upgrade for a total of 24gb RAM? I would buy two more sticks at 8gb each? Is it fine to have the two 4 gb and two 8gb? They do NOT have to be equal amounts (4x4x4x4)? Thank you in advance.
