To install a new module, insert the module into the desired slot in the tray and press it firmly in place. Push the tray back up until it locks in place.
Re-insert the RAM access door back into its place.

If you have two original RAM sticks, they’re installed in alternating slots, so there’s no need to move anything around to install two more - just use the empty slots.

Ich habe diese Anleitung genutzt bei meinem 27“ late 2013 Mac. Zu den vorhandenen Speichern von 2x4GB habe ich in die leeren Slots je einen 8GB Speicher eingesetzt. Das ging problemlos so wie beschrieben. Habe kein Werkzeug gebraucht. Die Taste zum Öffnen konnte ich mit dem Daumennagel hineindrücken. Der gesamte Speicher wird mit 24GB angezeigt. Vielen Dank für diese Hilfe!

Hello. My Imac (27-inch, Late 2012) has the original memory (2x4GB Elpida) in slots 1 and 2. When trying to install in slots 1+3, 1+4, 2+3, 2+4 it beeps three times and the Mac does not start. Replacing the original memory in slots 1+2 with new memory (2x8GB) is successful. Can not add memory to slots 3 and 4 (old memory or new). Please advise where to look for the problem.
