How much RAM do I need?
The more memory your computer has, the more programs you can run simultaneously, and the better performance you get from your computer. How much memory is right for you?
Choose 512MB of memory to support most day-to-day tasks such as email, word processing, spreadsheets, web browsing, and basic iLife '06 tasks.
Select 1GB of memory (two 512MB modules) if you'll be photo editing, creating illustrations, or building complex presentations.
Upgrade to the 2GB option (two 1GB modules) if you plan to use your system regularly for sound design, video editing, DVD authoring, animation, and other intensive tasks.
The Intel iMac uses one of the fastest memory technologies available today—667 MHz, double data rate (DDR2), synchronous dynamic random-access memory (SDRAM). It ensures high performance and reliability by synchronizing memory speed with the speed of the central processor so that data can be delivered continuously and more rapidly to the processor. And if both slots are loaded with an equal amount of RAM -- which is strongly recommended -- you can take advantage of the system's dual-channel memory architecture for an additional performance boost.
