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.
BIOS Setting
Configure the system memory in the Advanced Chipset Features
submenu (“DRAM Clock/Drive Control” section) of the BIOS.
