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.

CPU (Central Processing Unit)
Hardware Setup
The mainboard supports AMD
mainboard uses a CPU socket called Socket AM2 (940-pin) 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://global.msi.com.tw/index.php?func=cpuform
®
Athlon64 / Athlon64x2 / Sempron AM2 processors. The
Important
1. Overheating will seriously damage the CPU and system. Always make
sure the cooling fan can work properly to protect the CPU from overheating.
2. Make sure that you apply an even layer of heat sink paste (or thermal tape)
between the CPU and the heatsink to enhance heat dissipation.
3. 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.

CPU Installation Procedures for Socket AM2
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.
Sliding
Plate
90 degree
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.

Hardware Setup
Installing AMD Socket AM2 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.
Important
Mainboard photos shown in this section are for demonstration of the cooler
installation for Socket AM2 CPUs 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.
3.Fasten down the lever.
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 .
Fixed Lever
4.Attach the CPU Fan cable to the CPU
fan connector on the mainboard.
* 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.

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: 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.
