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 supports 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 Memory section) for detailed specification of the memory supported by the system board.
