uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the measures listed
below.
† Reorient or relocate the receiving antenna.
† Increase the separation between the equipment and receiver.
† Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
† Consult the dealer or an experienced radio/television technician for help.
Notice 1
The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
Notice 2
Shielded interface cables and A.C. power cord, if any, must be used in order to
comply with the emission limits.

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/ FX & Sempron processors. The 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://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.

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 .

Installing DDRII 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 module is properly inserted in the
DIMM slot.
3. The plastic clip at each side of the DIMM slot will automatically close.

Important
-DDRII modules are not interchangeable with DDR and the DDRII standard is
not backwards compatible. You should always install DDRII memory modules in the DDRII DIMMs and DDR memory modules in the DDR DIMMs.
-In dual-channel mode, make sure that you install memory modules of the
same type and density in differentchannel DDR DIMMs.
-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: 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).
There is also a foolproof design on pin 11, 12, 23 & 24 to avoid
wrong installation.

Hardware Setup
Important Notification about Power Issue
NForce chipset is very sensitive to ESD (Electrostatic Discharge), therefore this
issue mostly happens while the users intensively swap memory modules under S5
(power-off) states, and the power code is plugged while installing modules. Due to
several pins are very sensitive to ESD, so this kind of memory-replacement actions
might cause system chipset unable to boot. Please follow the following solution to
avoid this situation.
Unplug the AC power cable (shown in figure 1) or unplug the JPWR1/ JPWR2 & JPW1
power connectors (shown in figure 2 & figure 3) before the 1st installation or during
system upgrade procedure.

ATA133 Hard Disk Connectors: IDE1
The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100/133
controller that provides PIO mode 0~4, Bus Master, and Ultra DMA 66/
100/133 function. You can connect hard disk drives, CD-ROM and other
IDE devices.
The Ultra ATA133 interface boosts data transfer rates between the
computer and the hard drive up to 133 megabytes (MB) per second. The
new interface is one-third faster than earlier record-breaking Ultra ATA/
100 technology and is backwards compatible with the existing Ultra ATA
interface.
IDE1 (Primary IDE Connector)
IDE1 can connect a Master and a Slave drive. You must configure the
second hard drive to Slave mode by setting the jumper accordingly.
Important
IDE1
If you install two hard disks on IDE cable, you must configure the second
drive to Slave mode by setting its jumper. Refer to the hard disk documentation supplied by hard disk vendors for jumper setting instructions.

Fan Power Connectors: CPUFAN1, SYSFAN1, NBFAN1 & PWRFAN1
The fan power connectors support system cooling fan with +12V. When connecting
the wire to the connectors, always take 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.

1.Please refer to the recommended CPU fans at AMD® official website or
consult the vendors for proper CPU cooling fan.
2.Always consult the vendors for proper CPU cooling fan.
3. Fan/heatsink with 3 or 4 pins are both available for CPUFAN1/ SYSFAN1.
4.CPUFAN1 supports fan control. You can setup it in H/W Monitor of BIOS
Setup.
Chassis Intrusion Switch Connector: JCI1
This connector connects to a 2-pin chassis switch. If the chassis is opened, the
switch will be short. The system will record this status and show a warning message on the screen. To clear the warning, you must enter the BIOS utility and clear the
record.
Aux Line-In Connector: JCD1
The connector is for TV/ DVD add-on card with Line-in connector.
