MSI Special Feature

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.

MSI Reminds You...

Items shown on Core Center vary depending on your system status.

Hardware Setup

Central Processing Unit: CPU

The mainboard supports Intel® Pentium 4 Prescott processor. 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.

MSI Reminds You...

Overheating

Overheating will seriously damage the CPU and system, always make
sure the cooling fan can work properly to protect the CPU from
overheating.

Replacing the CPU

While replacing the CPU, always turn off the ATX power supply or
unplug the power supply’s power cord from grounded outlet first to
ensure the safety of CPU.

Overclocking

This motherboard 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 & 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.

2.Remove the cap from lever hinge
side (as the arrow shows).

4.Open the load lever.3.The pins of socket reveal.

2-4

Hardware Setup

5.Lift the load lever up and open the
load plate.

7.Visually inspect if the CPU is
seated well into the socket. If not,
take out the CPU with pure vertical
motion and reinstall.

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.

8.Cover the load plate onto the
package.

MSI Reminds You...

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.

2-5

MS-7222 Micro-ATX 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.

2-6

locking

switch

MSI Reminds You...

1.Check the information in PC Health Status 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 step 1) to avoid damaging.

3. Please note that the mating/unmating durability of the CPU is 20 cycles.
Therefore we suggest you do not plug/unplug the CPU too often.

Hardware Setup

Memory

The mainboard provides 2 slots for 240-pin DDR2 DIMM, which supports the

memory size up to 2GB.

Since DDR2 modules are not interchangeable with DDR1 and the DDR2 stand­ard is not backward compatible, you should always install DDR2 memory module in
the DDR2 slot. Otherwise, you are not able to boot up your system and your mainboard
might be damaged.

Introduction to DDR2 SDRAM

DDR2 is a new technology of memory module, and its speed is the top limit of
current DDR1 technology. DDR2 uses a 1.8V supply for core and I/O voltage, com­pared to 2.5V for DDR1, and requires 28% less power than DDR1 chips. DDR2 truly
is the future of memory, but will require some changes as the technology is not
backwardly compatible and only motherboards specifically designed for DDR2 memory
will be able to support these chips.

DDR2 incorporates new features at the chip level that give it better signal
integrity, thereby enabling higher clock speeds.

DDR2 modules have 240 pins, versus 184 pins on a DDR1 module, and the
length of DDR2 module is 5.25”. DDR2 modules have smaller and tighter spaced pins.
The height of DDR2 modules varies, but they will typically be less than 1.3” in height.

Installing DDR2 Modules

1. The DDR2 DIMM has only one notch on the center of module. The module 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.

3. The plastic clip at each side of the DIMM slot will automatically close.

Volt

MSI Reminds You...

You can barely see the golden finger if the module is properly in­serted in the socket.
