CPU (Central Processing Unit)
When you are installing the CPU, make sure to install the cooler to prevent
overheating. If you do not have the CPU cooler, consult your dealer 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.
Replaceing 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+
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 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.

Open Lever
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.
En-6
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.
Engli sh
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 .

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. The plastic
clip at each side of the DIMM slot will automatically close when the memory module
is properly seated.
Important
You can barely see the golden finger if the memory module is properly inserted
in the DIMM slot.
3. Manually check if the memory module has been locked in place by the DIMM slot
clips at the sides.

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.

ATX 24-Pin Power Connector: JPWR1
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).
