eMac (ATI Graphics) and eMac (USB 2.0) Memory - 5
Installing Memory
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)
