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.

Live Update
The Live Update 3™ is a tool used to detect and update your
BIOS/drivers/VGA BIOS/VGA Driver/Utility online so that you don’t
need to search for the correct BIOS/driver version throughout
the whole Web site. To use the function, you need to install the
“MSI Live Update 3” application. After the installation, the “MSI
Live Update 3” icon (as shown on the right) will appear on the
screen.
Double click the “MSI Live Update 3” icon, and the following
screen will appear:
Getting Started
Several buttons are placed on the left column of the screen. Click the desired button
to start the update process.
Live BIOS – Updates the BIOS online.
Live Driver – Updates the drivers online.
Live VGA BIOS – Updates the VGA BIOS online.
Live VGA Driver – Updates the VGA driver online.
Live Utility – Updates the utilities online.
If the product you purchased does not support any of the functions listed above, a
“sorry” message is displayed. For more information on the update instructions, insert
the companion CD and refer to the “Live Update Guide” under the “ Manual” Tab.

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 Intel® Pentium 4 series processors. The mainboard uses a
CPU socket called LGA775. When you are installing the CPU, make sure to install
the cooler to prevent overheating. If you do not have the CPU cooler, 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 & Cooler Installation
When you are installing the CPU, make sure the CPU has a cooler attached on
the top to prevent overheating. If you do not have the cooler, contact your dealer
to purchase and install them before turning on the computer. Meanwhile, do not forget
to apply some silicon heat transfer compound on CPU before installing the heat sink/
cooler fan for better heat dispersion.
Follow the steps below to install the CPU & cooler correctly. Wrong installation will
cause the damage of your CPU & mainboard.
1.The CPU socket has a plastic cap on
it to protect the contact from damage.
Before you install the CPU, always
cover it to protect the socket pin.
3.The pins of socket reveal.
2.Remove the cap from lever hinge
side (as the arrow shows).
4.Open the load lever.
Important
1.Confirm if your CPU cooler is firmly installed before turning on your system.
2. Do not touch the CPU socket pins to avoid damaging.
3. The availability of the CPU land side cover depends on your CPU packing.

Hardware Setup
5.Lift the load lever up and open the
load plate.
6.After confirming the CPU direction
for correct mating, put down the
CPU in the socket housing frame.
Be sure to grasp on the edge of
the CPU base. Note that the alignment keys are matched.

7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.
8.Cover the load plate onto the
package.

MS-7267 Mainboard
9.Press down the load lever lightly
onto the load plate, and then secure the lever with the hook under
retention tab.
11.Press the four hooks down to fas-
ten the cooler. Then rotate the locking switch (refer to the correct direction marked on it) to lock the
hooks.
10. Align the holes on the mainboard
with the heatsink. Push down the
cooler until its four clips get
wedged into the holes of the
mainboard.
12.Turn over the mainboard to confirm that the clip-ends are correctly inserted.

Important
1.Check the information in BIOS (Chapter 3) for the CPU temperature.
2. Whenever CPU is not installed, always protect your CPU socket pin with the
plastic cap covered (shown in Figure 1) to avoid damaging.

Memory
The mainboard provides two 240-pin non-ECC DDRII DIMMs and supports dualchannel technology up to 2GB system memory.

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 DIMM memory module vertically into the DIMM slot. Then push it in until the
golden finger on the memory module is deeply inserted in the socket.
Important
You can barely see the golden finger if the module is properly inserted in the
socket.
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.
