■Electrostatic discharge (ESD) is the sudden and momentary electric current that flows between two objects at different electrical potentials. Normally it comes out as a spark which will quickly damage your electronic equipment. Please wear an electrostatic discharge (ESD) wrist strap when handling components such as a motherboard, CPU or memory.

■Ensure that the DC power supply is turned off before installing or removing CPU, memory, expansion cards or other peripherals. It is recommended to unplug the AC power cord from the power supply outlet. Failure to unplug the power supply cord may result in serious damage to your system.

!

Please carefully read the following procedures to install your computer :

■It is suggested to select high-quality, certified fans in order to avoid damage to the motherboard and CPU due to high temperature. Never turn on the computer if the CPU fan is not properly installed.

■We cannot guarantee that your system can operate normally when your CPU/Memory is overclocked. Normal operation depends on the overclocking capacity of your device.

■If there is any, when connecting USB, audio, 1394a, RS232 COM, IrDA or

S/PDIF cables to the internal connectors on the motherboard, make sure their pinouts are matching with the connectors on the motherboard. Incorrect connections might damage the motherboard.

■When handling the motherboard, avoid touching any metal leads or connectors.

■If there is a PCI Express x16 graphics card installed in your system, we recommend using a 24-pin ATX power supply to get the best performance.

■Before turning on the power, please make sure the power supply AC input voltage setting has been configured to the local standard.

■To prevent damage to the motherboard, do not allow screws to come in contact with the motherboard circuit or its components. Also, make sure there are no leftover screws or metal components placed on the motherboard or within the computer casing.

■If you are uncertain about any installation steps or have a problem related to

the use of the product, please consult a certified computer technician.

This chapter introduces the hardware installation process, including the installation of the CPU, memory, power supply, slots, pin headers and the mounting of jumpers. Caution should be exercised during the installation of these modules. Please refer to the motherboard layout prior to any installation and read the contents in this chapter carefully.

This chapter includes the following information :

■Install the CPU and CPU Cooler

■Install the Memory

■Install an Expansion Card

■Install other Internal Connectors

■Jumpers

This motherboard supports low power energy-saving CPUs (drawing less than

65W under normal operation).

This currently includes most Intel® CoreTM 2 Duo processors, and all Pentium® Dual-Core and Celeron® models.

CPUs with a power rating higher than 65W are not supported, and will result in automatic shut-down of the system.

!

Read the following guidelines before you begin to install the CPU :

	■	Make sure that the motherboard supports the CPU.
2	■	Always turn off the computer and unplug the power cord from the power supply before
		installing the CPU to prevent hardware damage.
	■	Locate the Pin-1 of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or
		you may locate the notches on both sides of the CPU and alignment keys on the CPU
		socket.)
	■	Apply an even and thin layer of thermal grease on the surface of the CPU.
	■	Do not turn on the computer if the CPU cooler is not installed, otherwise overheating
		and damage of the CPU may occur.
	■	Set the CPU host frequency in accordance with the CPU specifications. It is not
		recommended that the system bus frequency be set beyond hardware specifications
		since it does not meet the standard requirements for the peripherals. If you wish to
		set the frequency beyond the standard specifications, please do so according to your
		hardware specifications including the CPU, graphics card, memory, hard drive, etc.
		Hyper-Threading Technology System Requirements:
		(Go to Intel's website for more information about the Hyper-Threading Technology)
	■	An Intel® CPU that supports HT Technology
	■	A chipset that supports HT Technology
	■	An operating system that is optimized for HT Technology
	■	A BIOS that supports HT Technology and has it enabled

!Read the following guidelines before you begin to install the memory :

	■	Make sure that the motherboard supports the memory. It is recommended that memory
		of the same capacity, brand, speed, and chips be used.	2
	■	Always turn off the computer and unplug the power cord from the power outlet before
		installing the memory to prevent hardware damage.
	■	Memory modules have a foolproof design. A memory module can be installed in only
		one direction. If you are unable to insert the memory, switch the direction.

Dual Channel Memory Configuration

This motherboard provides two DDR2 memory sockets and supports Dual Channel Technology. When memory is installed, the BIOS will automatically check the memory in your system.

Two DDR2 memory sockets are divided into two channels :

Channel 0 : DIMM1

Channel 1 : DIMM2

The combinations of DIMM modules are :

	DIMM1	DIMM2
Single Channel	DS/SS	-
Single Channel	-	DS/SS
Dual Channel	DS/SS	DS/SS

2-5 Jumpers

For some features needed, users can change the jumper settings on this motherboard to modify them. This section explains how to use the various functions of this motherboard by changing the jumper settings. Users should read the following content carefully prior to modifying any jumper setting.

Description of Jumpers

1.For any jumper on this motherboard, Pin 1 can be identified by the bold silkscreen next to it.

However, in this manual, Pin 1 is simply labeled as “1”.

2.The following table explains different types of the jumper settings. "Closed" means placing a jumper cap on the two pins to temporarily short them. The shorting can also be done by touching two pins by a screwdriver for a few seconds, but using jumper cap is recommended. It can prevent hazardous ESD (Electrical Static Discharge) problem.

Jumper	Diagram	Definition	Description
	1	1-2	Set Pin 1 and Pin 2 closed
1		2-3	Set Pin 2 and Pin 3 closed

	1	Closed	Set two pins closed
1		Opened	Set two pins opened

Clear CMOS Jumper: CLR_CMOS

The motherboard uses CMOS RAM to store the basic hardware information (such as BIOS data, date, time information, hardware password...etc.). Clear CMOS data is the fast way to go back to factory default when the BIOS settings were mistakenly modified.

The steps to clear CMOS data are :

1.Turn off the computer, unplug the power cord from the power outlet.

2.Remove jumper cap from pins 2-3, put it onto pins 1-2 to short them. This will clear CMOS data.

3.Return the setting to its original with pins 2-3 closed.

4.Plug in the power cord to your computer and turn it on.

5.Go to BIOS Setup to configure new system as described in next chapter.
