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

CPU & Cooler Installation

When you are installing the CPU, make sure the CPU has a cooler at-

tached 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 has a land side cover on the
bottom to protect the CPU contact from
damage. Rotate it to make the pin 1
indicator (yellow triangle) in the right­bottom corner.

land side cover

3.Use 2 hands to remove the land side
cover (if any). Please note not to touch
the pins.

2.Take out the accompanying CPU Clip
and rotate it for the same direction
as the CPU (Pin 1 indicator is in the
left-bottom corner).

4.Align the two pin 1 indicators (the
triangles on the CPU & the CPU Clip),
and use the CPU Clip to clip the CPU
up, pressing the clips on both sides
to the center, as the arrows shown.

2-4

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.

Hardware Setup

5.The CPU has a plastic cap on it to
protect the contact from damage.
Before you have installed the CPU,
always cover it to protect the socket
pin.

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

6.Remove the cap from lever hinge side
(as the arrow shows). The pins of
socket reveal.

8.Correctly align the triangle of CPU Clip
with the CPU chamfer, and the square
on the CPU Clip to the hook of the
socket.

9.Use your thumb and the middle fin­gers to push the clips to release the
CPU, then press down the CPU with
your index finger to allow the whole
module to be installed onto the CPU
socket.

10.The CPU is installed well on the CPU
socket.

2-5

MS-7204 mBTX Mainboard

11.Visually inspect if the CPU is seated
well into the socket, then remove the
CPU Clip with 2 fingers. Then cover
the load plate onto the package.

13.Position the mainboard into the chas-

sis and use the retaining screws to
secure it into the place. Then align
the holes on the mainboard and chas­sis with the cooler.

12. Press down the load lever lightly
onto the load plate, and then secure
the lever with the hook under reten­tion tab.

14.Put down the cooler and use the

retaining screws of the cooler to se­cure it into the place. Make sure the
cooler is in the proper orientation, the
cooler will only fit in the right
orientation. (Please refer the pictures
below.)

MSI Reminds You...

1.Check the information in PC Health Status of H/W Monitor 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.

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 4 slots for 240-pin DDR2 DIMM, which supports the

memory size up to 4GB.

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 (DIMM1~DIMM4). Otherwise, you are not able to boot up your system
and your mainboard might be damaged.

For the updated supporting memory modules, please visit http://www.msi

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.

Memory Module Population Rules

Install at least one DIMM module on the slots. Each DIMM slot supports up to a
maximum size of 1GB. Users can install either single- or double-sided modules to
meet their own needs. Please note that each DIMM can work respectively for

single-channel DDR, while both channels (in different color) populated
with same amount of memory size will work as dual-channel DDR.
