RAMJET Inc. - High Performance Mac Memory

Motherboard RAM: 0mb
User Slot: 1 SO-DIMM
Apple Slot: 1 DIMM

In early 2003, Apple upgraded the iMac Flat Panel's memory controller to run high-speed DDR memory. Earlier models all run standard SDRAM.

The SDRAM version has runs maximum of 1Gig (two 512mb modules), and the DDR version can run a maximum of 2Gigs (two 1Gig modules).

If you don't know which version you have, please consult the Memory Overview in your Apple System Profiler. You can get to the System Profiler by selecting "About This Mac" in your Apple Menu, and by clicking on the "More Info..." button.

User Slot:
The User Slot is the memory slot on the bottom of the machine. When you purchase your new iMac, this is the slot that will be empty. This slot uses a SO-DIMM.

Apple Slot:
Your new iMac will arrive with either a 128mb or a 256mb DIMM already installed. In order to upgrade the RAM in this Apple slot, you will need to remove the original RAM first. This slot uses a standard Long-DIMM.
