MSI Reminds You...

1.Please note that users cannot install OS, either WinME or Win98, in their SATA hard drive. Under these two OSs, SATA can only be used as a normal storage device.

2.To create a bootable RAID volume for a Windows 2000 environment, Microsoft’s Windows 2000 Service Pack 4 (SP4) is required. As the end user cannot boot without SP4, a combination installation CD must be created before attempting to install the operating system onto the bootable RAID volume.

To create the combination installation CD, please refer to the following website:

Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon64 processor. The mainboard uses a CPU socket called Socket-939 for easy CPU installation. When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.

For the latest information about CPU, please visit http://www.msi.com.tw/program/ products/mainboard/mbd/pro_mbd_cpu_support.php.

MSI Reminds You...

Overheating

Overheating will seriously damage the CPU and system, always make sure the cooling fan can work properly to protect the CPU from overheating.

Replacing the CPU

While replacing the CPU, always turn off the ATX power supply or unplug the power supply’s power cord from grounded outlet first to ensure the safety of CPU.

Overclocking

This motherboard is designed to support overclocking. However, please make sure your components are able to tolerate such abnormal setting, while doing overclocking. Any attempt to operate beyond product specifications is not recommended. We do not guarantee the damages or risks caused by inadequate operation or beyond product specifications.

CPU Installation Procedures for Socket 939

1.Please turn off the power and unplug the power cord before installing the CPU.

		Open Lever
	Sliding	90 degree
	Plate

2. Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90-de- gree angle.

Gold arrow

3. Look for the gold arrow. The gold arrow should point towards the lever pivot. The CPU can only fit in the correct orientation.

4.If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen. Please note that any violation of the correct installation procedures may cause permanent damages to your mainboard.

5.Press the CPU down firmly into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket.

Installing AMD Athlon64 CPU Cooler Set

When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.

1.Detach the shield of the backplate’s paster.

2.Turn over the mainboard, and install the backplate to the proper position.

3.Turn over the mainboard again, and place the mainboard on the flat surface.

Locate the two screw holes of the mainboard.

4.Align the retention mechanism and the backplate.

Fix the retention mechanism and the backplate with two screws.

5.Position the cooling set onto the retention mechanism.

Hook one end of the clip to hook first, and then press down the other end of the clip to fasten the cooling set on the top of the retention mechanism.

6.Locate the Fix Lever, Saftey Hook and the Fixed Bolt.

Lift up the intensive fixed lever.

Safety Hook

7. Fastened down the lever.

8.Make sure the safety hook completely clasps the fixed bolt of the retention mechanism.

9.Attach the CPU Fan cable to the CPU fan connector on the mainboard.

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 singleor 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.

MSI 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 unkonwn 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).

1.The maximum memory speed decreases when the following two Memory Combination is selected (you can also refer to the Recommended Memory Combination list shown in the previous page:

-Each channel is installed with two double-sided memory modules

-Both DIMM1 and DIMM3 slots are installed with double-sided memory module.

2.Due to the South Bridge resource deployment, the system density will only be detected up to 3+GB (not full 4GB) when each DIMM is installed with an 1GB memory module.

Installing 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.

Hardware Setup

Important 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 chipset system unable to boot. Please follow the following solution to avoid this situation.

Unplug the AC power cable (shown in figure 1) or unplug the ATX1 & JPW1 power connectors (shown in figure 2 & figure 3) before the 1st installation or during system upgrade procedure.

Fan Power Connectors: CPUFAN1 / SFAN1 / SFAN2 / NBFAN1

The CPUFAN1 (processor fan), SFAN1 (system fan 1), SFAN2 (system fan 2) and NBFAN1 (NorthBridge Chipset fan) support system cooling fan with +12V. It supports three-pin head connector. When connecting the wire to the connectors, always take note that the red wire is the positive and should be connected to the +12V, the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset on-board, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control.
