2.2 System Memory
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) is a fast memory
interface technology that uses
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.
The system board also supports the ECC (Error Checking and
Correction) function. To use this function, you must install DIMM that
supports parity. Refer to chapter 1 (System Memory section) for
detailed specification of the memory supported by the system
board.
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.
