2-7 Hardware SetupDIMM 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 single-channel 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.Memory 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.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 modules on the DDR DIMM slots (DDR 1~4).

2-8 MS-7100 ATX MainboardMSI Reminds You... -Dual-channel DDR works ONLY in the 3 combinations listed in the table shown in the previous page. -Please select the identical memory modules to install on the dual channel, and DO NOT install three memory modules on three DIMMs, or it may cause some failure. -Always insert the memory modules into the GREEN slots first, and it is strongly recommended not to insert the memory modules into the PURPLE slots while the GREEN slots are left empty. -This mainboard DO NOT support the memory module installed with more than 18 pieces of IC (integrated circuit).

2-9 Hardware SetupInstalling DDR Modules 1.The DDR DIMM has only one notch on the center of module. The module will only fit in the right orientation. 2.Insert the DIMM memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the socket. 3.The plastic clip at each side of the DIMM slot will automatically close.VoltNotchMSI Reminds You... You can barely see the golden finger if the module is properly in- serted in the socket.
2-10 MS-7100 ATX MainboardPower 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.

These two connectors connect to the ATX power supply and have to work together to ensure stable operation of the mainboard. 2. Power supply of 450 watts (and above) is highly recommended for system stability. 3. For ATX 12V power connection, it should be greater than 18A. 4. For this model, you must use the power supply that with a -5V pin supply.
2-11 Hardware SetupImportant Notification about Power Issue NForce chipset is very sensitive to ESD (Electrostatic Discharge), therefore this issue mostly happens while the users intensively swap memory modules under S5 (power-off) states, and the power code is plugged while installing modules. Due to several pins are very sensitive to ESD, so this kind of memory-replacement actions might cause system chipset unable to boot. Please follow the following solution to avoid this situation. Unplug the AC power cable (shown in figure 1) or unplug the JPWR1 & JPWR2 power connectors (shown in figure 2 & figure 3) before the 1st installation or during system upgrade procedure. Figure 1: Unplug the AC power cable Figure 2: Unplug the JPWR1 power conn.Figure 3: Unplug the JPWR2 power conn.
