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.

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.
