Hardware Setup

Central Processing Unit: CPU

The mainboard supports Intel® Pentium 4 Series 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://global.msi.com.tw/index.
php?func=cpuform)

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. 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.

3. According to the Intel® North Bridge 945-family chipset spec,this
mainboard 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.

Spread Spectrum
When the motherboard’s clock generator pulses, the extreme values (spikes) of the
pulses creates EMI (Electromagnetic Interference). The Spread Spectrum function
reduces the EMI generated by modulating the pulses so that the spikes of the pulses
are reduced to flatter curves. If you do not have any EMI problem, leave the setting at
[Disabled] for optimal system stability and performance. But if you are plagued by EMI,
select the desired range for EMI reduction. Remember to disable Spread Spectrum
function if you are overclocking, because even a slight jitter can introduce a tempo­rary boost in clock speed which may just cause your overclocked processor to lock
up.

Important

1. If you do not have any EMI problem, leave the setting at [Disabled] for
optimal system stability and performance. But if you are plagued by
EMI, select the value of Spread Spectrum for EMI reduction.

2. The greater the Spread Spectrum value is, the greater the EMI is reduced,
and the system will become less stable. For the most suitable Spread
Spectrum value, please consult your local EMI regulation.

3. Remember to disable Spread Spectrum if you are overclocking be­cause even a slight jitter can introduce a temporary boost in clock
speed which may just cause your overclocked processor to lock up.
