Warning:
When the DIMM 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.
Warning:
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
fast memory interface technology that includes using the clock on the
chip to synchronize with the CPU clock so that the timing of the
memory chips and the timing of the CPU are synchronized. This
saves time during transmission of data, subsequently increasing
system performance.
