MSI Special Feature
PC Alert™ 4
The PC AlertTM 4 is a utility you can find in the CD-ROM disk. The utility is just like your
PC doctor that can detect the following PC hardware status during real time operation:
ö monitor CPU & system temperatures
ö monitor fan speeds
ö monitor system voltages
If one of the items above is abnormal, the program main screen will be immediately
shown on the screen, with the abnormal item highlighted in red. This will continue to
be shown until the condition returns to the normal status.
Adjusting Keys
Temperature
Modes
Users can use the Adjusting Keys to change the minimum and maximum threshold of
each item for the system to send out a warning message. Click Temperature to select
the temperature modes of either Fahrenheit (oF) or Celsius (oC). The PC Alert™ 4 icon
on the Status Area will show the current CPU temperature.

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 & Athlon FX 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 .
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 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 8 GB) 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 & JPW1 power
connectors (shown in figure 2 & figure 3) before the 1st installation or during system
upgrade procedure.

The first hard drive should always be connected to IDE1. IDE1 can
connect a Master and a Slave drive. You must configure the second
hard drive to Slave mode by setting the jumper accordingly.
IDE2 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.
Important
IDE1/ IDE2
If you install two hard disks on 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
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.
