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 accessib\
le 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.

Installing the Memory Module 
Note: If you are replacing a defective memory module, rather than adding a module, 
remove the defective module before proceeding. 
1.	Line up the notch on the memory module with the notch (circled below) on the 
memory slot. 
2.	Important:  Do not push the clips (circled below) when inserting memory. They are 
used to remove memory from the slot, not when inserting memory. These clips are 
fragile and can break.
