2.1Before you proceed

Take note of the following precautions before you install motherboard components or change any motherboard settings.

•Unplug the power cord from the wall socket before touching any component.

• Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.

•Hold components by the edges to avoid touching the ICs on them.

•Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that came with the component.

•Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, or components.

Onboard LED

The motherboard comes with a standby power LED. The green LED lights up to indicate that the system is ON, in sleep mode, or in soft off mode. This is a reminder that you should shut down the system and unplug the power cable before removing or plugging in any motherboard component. The illustration below shows the location of the onboard LED.

2.3Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Extreme / Core™2 Quad / Core™2 Duo / Pentium® Dual-Core / Celeron® Dual-Core / Celeron® processors.

	•	Ensure that all power cables are unplugged before installing the CPU.
	•	If installing a dual-core CPU, connect the chassis fan cable to the CHA_FAN1
		connector to ensure system stability.
	•	Due to the chipset limitation, we recommend that you use FSB 800MHz CPU or
		above.
	•	Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
		the socket contacts are not bent. Contact your retailer immediately if the PnP cap
		is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
		components. ASUS will shoulder the cost of repair only if the damage is shipment/
		transit-related.
	•	Keep the cap after installing the motherboard. ASUS will process Return Merchandise		2
		Authorization (RMA) requests only if the motherboard comes with the cap on the		Chapter
		LGA775 socket.
	•	The product warranty does not cover damage to the socket contacts resulting from
		incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP
		cap.
2.3.1	Installing the CPU

To install a CPU:

1.Locate the CPU socket on the motherboard.

Before installing the CPU, ensure that the cam box is facing towards you and the load lever is on your left.

5.Position the CPU over the socket, ensuring that the gold triangle is on the bottom left corner of the socket, and then fit the socket alignment key into the CPU notch.

The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU!

6.Apply some Thermal Interface Material to the exposed area of the CPU that the heatsink will be in contact with, ensuring that it is spread in an even thin layer.

Some heatsinks come with pre-applied thermal paste. If so, skip this step.

The Thermal Interface Material is toxic and inedible. DO NOT eat it. If it gets into your eyes or touches your skin, wash it off immediately, and seek professional medical help.

To prevent contaminating the paste, DO NOT spread the paste with your finger directly.

2.3.2Installing the CPU heatsink and fan

The Intel® LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.

• When you buy a boxed Intel® processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, ensure that you use only Intel® certified multi directional heatsink and fan.

•Your Intel® LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.

Ensure that you have installed the motherboard to the chassis before you install the CPU fan and heatsink assembly.

If you purchased a separate CPU heatsink and fan assembly, ensure that the Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly.

	To install the CPU heatsink and fan:			A
	1.	Place the heatsink on top of the installed
				B
		CPU, ensuring that the four fasteners
				B
		match the holes on the motherboard.
	2.	Push down two fasteners at a time in
		a diagonal sequence to secure the		A
		heatsink and fan assembly in place.
		A	B
		B	A	1

Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan connector.

3.Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN.

DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector.

2.3.3Uninstalling the CPU heatsink and fan

To uninstall the CPU heatsink and fan:

1.	Disconnect the CPU fan cable from the		A
	connector on the motherboard.		B
2.	Rotate each fastener counterclockwise.		B
3.	Pull up two fasteners at a time in a
	diagonal sequence to disengage the		A
	heatsink and fan assembly from the
	motherboard.

2.4System memory

2.4.1Overview

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline Memory Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are notched differently to prevent installation on a DDR DIMM socket.

The figure illustrates the location of the DDR2 DIMM sockets:

2 Chapter

Recommended memory configurations

One DIMM:

You may install one memory module in any slot as a single-channel operation.

Two DIMMs (dual-channel operation):

Four DIMMs (dual-channel operation):

2-10	Chapter 2: Hardware information

2.4.2Memory configurations

You may install 512MB, 1GB, 2GB and 4GB unbuffered ECC and non ECC DDR2 DIMMs into the DIMM sockets.

• You may install varying memory sizes in ChannelAand Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration.Any excess memory from the higher-sized channel is then mapped for single-channel operation.

•We recommend that you install the memory modules from the yellow slots for better overclocking capability.

•Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

•Due to the memory address limitation on 32-bit Windows OS, when you install 4GB or more memory on the motherboard, the actual usable memory for the OS can be about 3GB or less. For effective use of memory, we recommend that you do any of the following:

-Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.

-Install a 64-bit Windows OS when you want to install 4GB or more on the motherboard.

•This motherboard does not support DIMMs made up of 256 megabit (Mb) chips or less.

• The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value. To operate at the vendor-marked or at a higher frequency, see section 3.5 Ai Tweaker menu for manual memory frequency adjustment.

•For system stability, use a more efficient memory cooling system to support a full memory load (4 DIMMs) or overclocking condition.
