You can install PC2700/DDR333, PC2100/DDR266 or PC1600/ DDR200 modules on the DDR DIMM slots (DIMM 1~2). DDR DIMM Slots (DIMM 1~2) 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. 2-7 MS-6785 M-ATX Mainboard DIMM Module Combination Install at least one DIMM module on the slots. You can install either single- or doublesided modules to meet your own needs. Memory modules can be installed in any combination as follows: Slot DIMM 1 (Bank 0 & 1) DIMM 2 (Bank 2 & 3) Memory Module S/D S/D Total Memory 64MB~1GB 64MB~1GB 64MB~2GB D: Double Side Maximum System Memory Supported S: Single Side Installing DDR Modules 1. Then push it in until the golden finger on the memory module is deeply inserted in the socket. You can barely see the golden finger if the module is properly inserted in the socket. The plastic clip at each side of the DIMM slot will automatically close. Volt Notch 2-8 Hardware Setup Power Supply The mainboard supports ATX power supply for the power system. Before inserting the power supply connector, always make sure that all components are installed properly to ensure that no damage will be caused. ATX 20-Pin Power Connector: CONN1 This connector allows you to connect to an ATX power supply. To connect to the ATX power supply, make sure the plug of the power supply is inserted in the proper orientation and the pins are aligned. Then push down the power supply firmly into the connector. ATX 12V Power Connector: JPW1 This 12V power connector is used to provide power to the CPU.
