RAM Expansion Module Specifications

The RAM expansion modules used in the eMac and eMac (ATI Graphics) computers are 168-pin SDRAM DIMMs (dual inline memory modules) that are 3.3 V, unbuffered, 8-byte, non-parity, PC-133 compliant.

The RAM expansion modules used in the eMac (USB 2.0) computers are 184-pin SDRAM DIMMs (dual inline memory modules) that are 2.5 V, unbuffered, 8-byte, non-parity, and PC2700 compliant. The speed of the SDRAM devices must be rated at 167 MHz (7 ns) or faster.

Important: The memory expansion cards (DIMMs) must use SDRAM devices as specified above. DIMMs for previous models of eMac or DIMMs that use EDO or SGRAM devices will not work. If they are installed, the computer will beep, and the power light will flash several times when you turn on the computer. This indicates that the computer cannot find any useable RAM.

Procedure

1.Remove the replacement memory from its static-proof bag, taking care not to touch the connectors or chips.

2.Push down the ejectors on the slot of the memory module you want to install or replace memory. (Figure 5)
