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 mainboard 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.

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 Memor y section) for detailed specification of the memory supported by the system board. “Memor y Frequency For” in the Advanced Chipset Features submenu of the BIOS must be set accordingly.
