    • Remove a stick of RAM by grabbing it with two hands and pulling straight out of the RAM tray.

    • RAM modules are keyed so that they can only be installed in the proper orientation. Note where the shorter section of contacts is when removing, and reinstalling, your RAM.

    • 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.

    • The RAM access door is not symmetrical. If it is not flush on both ends, try putting it in the other way.

    • Re-insert the RAM access door back into its place.

At the end: "To reassemble your device, follow these instructions in reverse and use our adhesive strip replacement guide to reattach the display glass."

This does not make sense for a memory replacement guide.

I am thinking about getting me an iMac 5K but not really interested in overpaying for my RAM - can I access all 4 slots in the newest iMac 5K so I could buy the entry level with 8GB and then upgrade it to 32GB myself?

Yes, but make sure they are the same frequency so there won't be any issues. (1867)

Is it possible for 4GB x 2 model to add 8GB x 2 and having 24GB RAM
