MSI Reminds You...

1. Now the nVidia nForce4 system driver is only available for Windows 2000 and Windows XP.

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.

MS-7125 M-ATX Mainboard

CPU Installation Procedures for Socket 939

1. Please turn off the power and

unplug the power cord before installing the CPU.

2. Pull the lever sideways away

from the socket. Make sure to raise the lever up to a 90-degree angle.

3. Look for the gold arrow on the CPU. The gold arrow should point as shown in the picture. 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.

Hardware Setup

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, Safety Hook

and the Fixed Bolt. Lift up the intensive fixed lever.

7. Fasten 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.

MSI Reminds You...

While disconnecting the Safety Hook from the fixed bolt, it is necessary to keep an eye on your fingers, because once the Safety Hook is

disconnected from the fixed bolt, the fixed lever will spring back instantly.

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 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 left to right)

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 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.

E-2-7

MS-7125 M-ATX Mainboard

DIMM Module Combination

Install at least one DIMM module on the slots. You can install either single- or doublesided modules in any order to meet your own needs.

Memory modules can be installed in any combination as follows:

Slot Memory Module T otal Memory

DDR 1 (Bank 0 & 1) S/D 64MB~1GB

DDR 2 (Bank 2 & 3) S/D 64MB~1GB

Maximum System Memory Supported 64MB~2GB

S: Single Side D: Double Side

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.

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.

A TX 24-Pin Power Connector: ATX1

This connector allows you to connect an SSI power supply. To connect the

SSI 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.

You may use the 20-pin ATX power supply or 24-pin SSI

power supply as you like. If you’d like to use the ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand). There is also a foolproof design on pin 11, 12, 23 & 24 to avoid wrong installation.

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