Electrostatic Discharge (ESD)

Static electricity , a normal and natural phenomenon, builds up on y our body
as you walk around. You experience an electrostatic discharge (ESD) when
you touch an object and feel a spark. ESD can cause damage to the
internal components of your computer.

To avoid ESD damage, read and follow all instructions. If a grounding wrist
strap is included with your replacement memory, refer to the instructions
included for how to ground and use the strap.

About Memory

Memory cards called Dual Inline Memory Modules (DIMMs) provide
dynamic random-access memory (DRAM) to your computer. The DIMMs
are installed in three memory slots on the logic board.

DRAM DIMM

Your computer uses synchronous DRAM (SDRAM) DIMMs that must be
compatible with the computer’s specifications. Replace the DIMM in your
computer with the replacement DIMM provided in this package. Do not use
DRAM DIMMs from older computers, even if they fit into the DIMM slots.

Note:

Different size DRAM DIMMs can be installed in any order in any
DIMM slot. You also do not have to install DIMMs in pairs, as in some older
Macintosh computers.
