iMac Intel 27" Retina 5K Display RAM Replacement
By Sam Lionheart • Difficulty: Easy

Use this guide to remove, replace or upgrade the RAM in your iMac Intel 27" Retina 5K Display.

Step 1
  • 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.
