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 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 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.

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.

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

MSI Reminds You...

1. Confirm if your CPU cooler is firmly installed before turning on your
system.

2. Check the information in H/W Monitor in BIOS (refer to p.3-20 for
details) for the CPU temperature.

3. Do not touch the CPU socket pins to avoid damaging.

4. Whenever CPU is not installed, always protect your CPU socket pin
with the plastic cap covered (shown in Figure 1) to avoid damaging.

5. 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 184-pin DDR SDRAM DIMM (Double In­Line Memory Module) modules and supports the memory size up to 4GB. You can
install DDR400/DDR333 modules on the DDR DIMM slots (DIMM 1~4).

DDR DIMM Slots

(DIMM 1~4)

Introduction to DDR SDRAM

DDR (Double Data Rate) SDRAM is similar to conventional SDRAM, but dou­bles the rate by transferring data twice per cycle. It uses 2.5 volts as opposed to 3.
3 volts used in SDR SDRAM, and requires 184-pin DIMM modules rather than 168-pin
DIMM modules used by SDR SDRAM. Please note that the DDR SDRAM does not
support ECC (error correcting code) and registered DIMM.

DDR 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, but there are some rules while using dual-channel
DDR (Please refer to the suggested DDR population table on p.2-8). Users may install

memory modules of different type and density on different-channel DDR DIMMs.

However, the same type and density memory modules are necessary
while using dual-channel DDR, or instability may happen.
