2.2 System Memory
Warning:
Electrostatic discharge (ESD) can damage your system board, proces-
sor, 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 three 184-pin DDR DIMM
sockets. DDR (Double Data Rate) is a type of SDRAM that dou-
bles 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.
Refer to chapter 1 (System Memory section) for detailed specifi-
cation of the memory supported by the system board.
