MSI Special Feature
Core Center
The Core Center is a new utility you can find in the CD-ROM disk. The utility is just like
your PC doctor that can detect, view and adjust the PC hardware and system status
during real time operation.
In the left side it shows the current system status including the Vcore, 3.3V, +5V and
12V. In the right side it shows the current PC hardware status such as the CPU &
system temperatures and all fans speeds.
When you click the red triangles in the left and right sides, two sub-menus will open
for users to adjust the thresholds of system to send out the warning messages.
1-6
Getting Started
Left-wing: Current system status
In the left sub-menu, you can configure the settings of FSB, Vcore, Memory Voltage
and AGP Voltage by clicking the radio button next to each item and make it available
(the radio button will be lighted as yellow when selected), use the “+” and “-” buttons
to adjust, then click “OK” to apply the changes. Then you can click “Save” to save
the values you just configured.
Also you may click “Auto” to start testing the maximum CPU overclocking value. The
CPU FSB will automatically increase the testing value until the PC reboots. Or you may
click “Default” to restore the default values.
Right-wing: PC hardware status during real time operation
In the right sub-menu, here you can configure the PC hardware status such as CPU
& system temperatures and fan speeds. You may use the scroll bars to adjust each
item, then click “OK” to apply the changes. The values you set for the temperatures
are the maximum thresholds for the system for warnings, and the value for fan
speeds are the minimum thresholds.

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.
2-4
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.
2-5
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.

Hardware Setup
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 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.

Hardware Setup
Power Supply
ATX 24-Pin Power Connector: ATX1
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.
