MSI Special Feature

PC Alert™ 4

The PC AlertTM 4 is a utility you can find in the CD-ROM disk. The utility is just like your PC doctor that can detect the following PC hardware status during real time operation:

ö monitor CPU & system temperatures ö monitor fan speeds ö monitor system voltages

If one of the items above is abnormal, the program main screen will be immediately shown on the screen, with the abnormal item highlighted in red. This will continue to be shown until the condition returns to the normal status.

Adjusting Keys

Temperature

Modes

Users can use the Adjusting Keys to change the minimum and maximum threshold

of each item for the system to send out a warning message. Click Temperature to select the temperature modes of either Fahrenheit (oF) or Celsius (oC). The PC Alert™ 4 icon on the Status Area will show the current CPU temperature.

1-7

MS-7145 M-ATX Mainboard

Live Update

The Live Update 3™ is a tool used to detect and update your BIOS/drivers/VGA BIOS/VGA Driver/Utility online so that you don’t need to search for the correct BIOS/driver version throughout the whole Web site. To use the function, you need to install the “MSI Live Update 3” application. After the installation, the “ MSI Live Update 3” icon (as shown on the right) will appear on the screen. Double click the “ MSI Live Update 3” icon, and the following screen will appear:

Several buttons are placed on the left column of the screen. Click the desired button to start the update process.

Live BIOS – Updates the BIOS online. Live Driver – Updates the drivers online. Live VGA BIOS – Updates the VGA BIOS online. Live VGA Driver – Updates the VGA driver online. Live Utility – Updates the utilities online.

If the product you purchased does not support any of the functions listed above, a “sorry” message is displayed. For more information on the update instructions, insert the companion CD and refer to the “ Live Update Guide” under the “Manual” Tab.

Hardware Setup

Central Processing Unit: CPU

The mainboard supports AMD® Athlon64/ Sempron processor. The mainboard uses a CPU socket called Socket-754 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.

CPU Installation Procedures for Socket 754

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

Open Lever

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 of 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.

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.

6.Press down the other end of the clip to fasten the cooling set on the top of the retention mechanism.

8.Fasten down the lever.

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

7.Locate the Fix Lever, Safety Hook and the Fixed Bolt. Lift up the intensive fixed lever.

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 2 slots for 184-pin DDR DIMM (Double In-Line Memory Module) modules and supports the memory size up to 2GB. You can install DDR 333/ 400 modules on the DDR DIMM slots (DDR1/DDR2).

DDR1 DDR2

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.

MSI Reminds You...

- This mainboard DO NOT support the memory module installed with more than 18 pieces of IC (integrated circuit).

2-7

MS-7145 M-ATX Mainboard

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.

ATX 24-Pin Power Connector: ATX1

This connector allows you to connect an ATX 24-pin power supply. To connect the ATX 24-pin 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 as you like. If you’d like to use the 20-pin 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.
