Hardware Installation
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.

2.2 System Memory

The system board is equipped with two 184-pin DDR SDRAM
DIMM (Dual In-line Memory Module) sockets that support 2.5V
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 doubling the
speed of data transfer.
Refer to chapter 1 (System Memor y section) for detailed
specification of the memory supported by the system board.
