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® Sempron / Athlon64 / Athlon64 X2 AM2 processors in
Socket 940. 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 more information on compatible components, please visit http://www.msi.com
tw/program/products/mainboard/mbd/pro_mbd_cpu_support.php.
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.

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

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 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 the CPU from 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 purchased.
1.Position the cooling set onto the retention mechanism.
Hook one end of the clip to hook
first.
3.Fasten down the lever.
* 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.
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 .
