Part Location

The RAM expansion slot accommodates a standard DDR333 PC2700 complaint SO-

DIMM (small outline, dual inline memory) that uses DDR SDRAM devices.

Important: A RAM expansion SO-DIMM for the iMac (USB 2.0) computer must use DDR

SDRAM devices. If the user installs an SO-DIMM that uses single data rate (SDR),

SGRAM, or non-DDR SDRAM devices, the computer will beep twice when the user

attempts to restart the computer.

Note: This procedure describes installing a SO-DIMM memory module in the user-

accessible slot. The iMac (USB 2.0) computer can accommodate standard SO-DIMMs

with a height of 1.0 or 1.25 inches.
