Warning:
To ensure proper boot up and operation of your system, you
must power-off the system then turn off the power supplys
switch or unplug the AC power cord prior to altering the setting
of a jumper or replacing the CPU.
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
protection.
The system board is equipped with two 168-pin DIMM (Dual In-line
Memory Module) sockets that support VCM or PC SDRAM DIMM.
PC SDRAM (Synchronous Dynamic Random Access Memory) uses a
