Hardware Setup Memory The mainboard provides 4 slots for 184-pin DDR SDRAM DIMM (Double In-Line Memory Module) modules and supports the memory size up to 4GB. You can install DDR266/ 333/400/433/466/500/533 modules on the DDR DIMM slots (DDR 1~4). For the updated supporting memory modules, please visit http://www.msi.com.tw/ program/products/mainboard/mbd/pro_mbd_trp_list.php. DIMM1~4 (from bottom to top) Introduction to DDR SDRAM DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as opposed to 3.3 volts used in SDR SDRAM, and requires 184-pin DIMM modules rather than 168-pin DIMM modules used by SDR SDRAM. High memory bandwidth makes DDR an ideal solution for high performance PC, workstations and servers. DIMM Module Combination Install at least one DIMM module on the slots. Each DIMM slot supports up to a maximum size of 1GB. Users can install either single- or double-sided modules to meet their own needs. Please note that each DIMM can work respectively for singlechannel DDR, but there are some rules while using dual-channel DDR (Please refer to the suggested DDR population table below). Users may install memory modules of different type and density on different-channel DDR DIMMs. However, the same type and density memory modules are necessary while using dual-channel DDR, or instability may happen. Please refer to the following table for detailed dual-channel DDR. Other combination not listed below will function as single-channel DDR. 2-7
