Hardware Setup
This chapter provides you with the information about hardware setup procedures. While doing the installation, be careful in holding the components and follow the installation procedures. For some components, if you install in the wrong orientation, the components will not work properly.
Use a grounded wrist strap before handling computer components. Static electricity may damage the components.

Hardware Setup
CPU (Central Processing Unit)
The mainboard supports AMD® Athlon64 X2/ Athlon64/ Sempron processors in Socket AM2, and supports Phenom X4/X3, Athlon X2, Sempron processors in Socket AM2+. The Socket AM2/ AM2+ offer a 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://global.msi.com.tw/index.php?func=cpuform
Important
Overheating
Overheating will seriously damage the CPU and system. Always make sure the cooling fan can work properly to protect the CPU from overheating. Make sure that you apply an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to enhance heat dissipation.
Replacing the CPU
While replacing the CPU, always turn off the ATX power supply or unplug the power supply’s power cord from the grounded outlet first to ensure the safety of CPU.
Overclocking
This mainboard 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 AM2/ AM2+
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-de- gree angle.

|
orientation.Lower the CPU down |
|
onto the socket. |
|
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 CPU Cooler Set
W hen 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.
Important
1.Read the CPU status in BIOS (Chapter 3).
2.Mainboard photos shown in this section are for demonstration of the CPU/ cooler installation only. The appearance of your mainboard may vary depending on the model you purchase.
1.Position the cooling set onto the retention mechanism.
Hook one end of the clip to hook first.
2.Then press down the other end of the clip to fasten the cooling set on the top of the retention mechanism. Locate the Fix Lever and lift up it .

Installing Memory Modules
1.The memory module has only one notch on the center and will only fit in the right orientation.
2.Insert the memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot.
Important
You can barely see the golden finger if the memory module is properly inserted in the DIMM slot.
3. The plastic clip at each side of the DIMM slot will automatically close.

Important
-DDR2 memory modules are not interchangeable with DDR and the DDR2 standard is not backwards compatible. You should always install DDR2 memory modules in the DDR2 DIMM slots.
-In Dual-Channel mode, make sure that you install memory modules of the same type and density in different channel DIMM slots.
-To enable successful system boot-up, always insert the memory modules into the DIMM1 first.
-Due to the chipset resource deployment, the system density will only be detected up to 7+GB (not full 8GB) when each DIMM is installed with a 2GB memory module.

Power Supply
ATX 24-Pin Power Connector: ATXPWR1
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.

Hardware Setup
Fan Power Connectors: CPUFAN1, SYSFAN1, SYSFAN2
The fan power connectors support system cooling fan with +12V. When connecting the wire to the connectors, always 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.
