Introduction

For an easy power boost, replace the RAM—the only upgrade that doesn't require cutting the adhesive behind the display.

What you need

While holding the display steady, use the flat end of a spudger to press in on the RAM door release button, located just above the power port.
You may have to press fairly hard—keep at it until the bottom of the door pops out about 0.25" from the rear of the iMac.

Step 2

Pull the RAM access door off the back of the iMac.

Step 3

The RAM tray is locked into its upright position with two grey tabs.
Use your thumbs or index fingers to unlock the tray by pushing the tabs outward, away from the RAM.
Pull the tabs out and down, swinging the RAM tray down to a near-horizontal position.

Step 4

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