Hardware Setup

This chapter provides you with the information about hard­ware setup procedures. While doing the installation, be
careful in holding the components and follow the installation
procedures. For some components, if you install in the wrong
orientation, the components will not work properly.
Use a grounded wrist strap before handling computer
components. Static electricity may damage the components.

ONLY FOR SERVICE PERSONEL

Always unplug the power cord before
inserting any add-on card or module.

Hardware Setup

CPU (Central Processing Unit)

This mainboard supports Intel® Smithfield Pentium D (8XX), Presler Pentium D (9XX)
and CoreTM 2 Duo / Core 2 Extreme / Core 2 Quad processors in the LGA775 package.
When you are installing the CPU, make sure to install the cooler to prevent overheating.
If you do not have the CPU cooler, consult your dealer before turning on the computer.

Important

Overheating

Overheating will seriously damage the CPU and system. Always make
sure the cooling fan can work properly to protect the CPU from
overheating. Make sure that you apply an even layer of thermal paste
(or thermal tape) between the CPU and the heatsink to enhance heat
dissipation.

Replaceing the CPU

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

Overclocking

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.

Important

1. DDR2 memory modules are not interchangeable with DDR and the
DDR2 standard is not backwards compatible. You should always install
DDR2 memory modules in the DDR2 DIMM slots.

2. In Dual-Channel mode, make sure that you install memory modules of
the same type and density in different channel DIMM slots.

3. To enable successful system boot-up, always insert the memory modules
into the DIMM1 first.

Overview

The built-in mainboard (MS-7407) is designed for Hetis G31 Series (MS-6470) barebone
only. Except the mainboard, the built-in components of the barebone include power
supply. In this chapter, we will show you how to install CPU, CPU Cooler, Memory
Modules, Card Reader, Hard Disk Drive (HDD) and Optical Disk Drive (ODD).

Installation Tools

Cross type screwdriver, can be used to do most of the
installation. Choose one with a magnetic head would be better.

Pliers, can be used as an auxiliary tool to connect some con­nectors or cables.

Forceps, can be used to pick up tiny screws or set up the
jumpers.

Rubber gloves, can prevent yourself from being incised and
suffering the static charge.

Installation Screws

Two types of screws are used in assembling the barebone: Round-headed screw
and thumb screw.

Round-headed screw: This type of screw is used to attach
the HDD and Card Reader to the tray.

Execute Disable Bit

Intel’s Execute Disable Bit functionality can prevent certain classes of mali­cious “buffer overflow” attacks when combined with a supporting operating
system. This functionality allows the processor to classify areas in memory by
where application code can execute and where it cannot. When a malicious
worm attempts to insert code in the buffer, the processor disables code
execution, preventing damage or worm propagation.

Intel® SpeedStepTM tech

Intel’ SpeedStep technology can provide average power savings depending
on system usage and design. This technology allows the system to dynamically
adjust processor voltage and core frequency, which can result in decreased
average power consumption and decreased average heat production.

Spread Spectrum Clock

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.

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.
