RAM Expansion Slots

The iMac has two RAM expansion slots. The slots accept standard PC-100 or PC-133, 168-pin DIMMs (dual inline memory modules) that use SDRAM devices. A DIMM for a iMac can contain either 64, 128, 256, or 512 MB of memory.

A door on the bottom of the computer provides access to the RAM expansion slots. Before opening the bottom door, the user should place the computer face down on a soft cloth.

When the door is open, the portion of the main logic board that contains the two RAM expansion slots is visible. One slot is normally occupied by the factory-installed RAM DIMM. Either RAM expansion slot can accept a user-installed DIMM.

Important

The user should be reminded to observe the usual precautions to avoid damage to the electronic components due to static electricity.
