I bought some extra ram for this Imac (2 x 8=16 Gb)
What to do with with the 2 x 4 gb (8GB) standard ram which was in this Imac?
Can I just add 2 x 8 gb ram? Or will this not work?
So, do i have to remove the 2 x 4 GB ram (standard) and than after removing them add the 2 x 8 GB ram?
iMac 27″, macOS 11.2
You can just add the additional RAM.
Yup... what dialabrain said. He’s 100% correct. Your iMac can have up to 64 gigs of RAM ( memory) ... you could try here: link
