  • 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.

To reassemble your device, follow these instructions in reverse order.
