Hardware Installation
System Memory
Important:
When the DRAM Power LED lit red, it indicates that power is present on
the DIMM sockets. Power-off the PC then unplug the power cord prior to
installing any memory modules. Failure to do so will cause severe dam-
age to the motherboard and components.
Important:
Electrostatic discharge (ESD) can damage your system board, processor,
disk drives, add-in boards, and other components. Perform the upgrade
instruction procedures described at an ESD workstation only. If such a
station is not available, you can provide some ESD protection by wearing
an antistatic wrist strap and attaching it to a metal part of the system
chassis. If a wrist strap is unavailable, establish and maintain contact
with the system chassis throughout any procedures requiring ESD pro-
tection.

The four DIMM sockets are divided into 2 channels:
Channel A - DIMM 1 and DIMM 2
Channel B - DIMM 3 and DIMM 4
For dual channel configuration, insert DIMMs in DDR2-1 and DDR2-3 or DDR2-2
and DDR2-4.
