Part Location
The iMac has two RAM expansion slots. The factory-installed RAM slot accepts a
standard PC133 168-pin DIMM (up to 512 MB in capacity) and is accessible only by an
Apple Authorized Service Provider. The user-accessible slot (shown above) accepts a
standard PC133 144-pin SO-DIMM and is normally used for added RAM. Only the SO-
DIMM slot is accessible by the user. A SO-DIMM for the iMac computer can contain either
64, 128, 256, or 512 MB of memory.
Note: This procedure describes installing a SO-DIMM memory module in the user-
accessible slot.
