2.2 System Memory
The system board is equipped with three
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.
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.
