    • 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.

I just purchased RAM and this guide was very accurate. Thank you.

Hi guys! I have to slot full with the basic amount of RAM (2 x 4 GB), can I install 2 x 8 GB in the other two slots available? I want to upgrade to 24 GB of RAM, but I don't know if there are any problem putting together 4 GB modules with 8 GB ones. I remember an old story about possible issues... Thanks for your replies! :-)

You should be fine with pairs of equal capacity. 2 X 4 GB and 2 X 8 GB

Usually best to install in pairs of similar sizes

I just upgraded mine from 16GB to 32GB. The only problem with this guide is that it says the difficulty is moderate. What could be easier? It took me less than five minutes, and most of that was unplugging/replugging stuff before and after the actual RAM upgrade.

I used a screwdriver to push on the little button that opens the door, as I didn't have a spudger handy.
