Warning:
Electrostatic discharge (ESD) can damage your system board, proces-
sor, 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 protec-
tion 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 proce-
dures requiring ESD protection.
System Memory
Warning:
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 damage to the motherboard and components.
The four DIMM sockets on the system board are divided into 2
channels:
Channel A - DDR2-1 and DDR2-2
Channel B - DDR2-3 and DDR2-4
