2.2 System Memory
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 184-pin DDR DIMM (Dual
In-line Memory Module) sockets that support unbuffered or registered
DDR SDRAM DIMM. Double Data Rate SDRAM (DDR SDRAM) is
a type of SDRAM that doubles the data rate through reading and
writing at both the rising and falling edge of each clock. This
effectively doubles the speed of operation therefore providing two
times faster data transfer.
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.
