This chapter provides step-by-step instructions on how to install components into the system.

Basic installation

2.1Preparation

Before you proceed, ensure that you have all the components you plan to install into the system.

Basic components to install

1.Central Processing Unit (CPU)

2.DDR2 Dual Inline Memory Module (DIMM)

3.Expansion cards

4.Hard disk drive

5.Optical disk drive

Tool

Phillips (cross) screw driver

2-2	Chapter 2: Basic installation

2.2Before you proceed

Take note of the following precautions before you install components into the system.

•Unplug the power cables before you touch any component in the system.

• Use a grounded wrist strap, or touch a safely grounded object or a metal object, such as the power supply case, before handling components 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 cable is detached from the power supply. Failure to do so may lead to personal injury and cause severe damage to the motherboard, peripherals, and components.

Onboard LED

The system motherboard comes with a standby power LED that lights up to indicate that the system is ON, in sleep mode, or in soft-off mode. This 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.

2.4Central Processing Unit (CPU)

2.4.1Overview

The motherboard comes with a surface mount LGA775 socket designed for the Intel® Core™2 Quad / Intel® Core™2 Extreme / Core™2 Duo / Pentium® Extreme / Pentium® D/ Pentium® 4 / Celeon® processors.

• Make sure that all power cables are unplugged before installing the CPU.

• Connect the chassis fan cable to the CHA_FAN1 connector to ensure system stability.

• Upon purchase of the motherboard, make sure 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

MerchandiseAuthorization (RMA) requests only if the motherboard comes with the cap on the 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.

2.4.2Installing CPU

To install a CPU:

1.Locate the CPU socket on the motherboard.

Before installing the CPU, make sure that the socket box is facing towards you and the load lever is on your left.

2.Press the load lever with your thumb

(A), then move it to the left (B) until it is released from the retention tab.

To prevent damage to the socket pins, do not remove the PnP cap unless you are installing a CPU.

6. Apply several drops of 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 preapplied thermal paste. If so, skip this step.

DO NOT eat the Thermal Interface Material. If it gets into your eyes or touches your skin, ensure that you wash it off immediately, and seek professional medical help.

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

7.	Close the load plate (A), then push
	the load lever (B) until it snaps into	A
	the retention tab.

2.4.3Installing the CPU fan and heatsink assembly

The Intel® Pentium® 4 LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.

•When you buy a boxed Intel® Pentium® 4 processor, the package

includes the CPU fan and heatsink assembly. If you buy a CPU separately, make sure that you use only Intel® certified multi directional heatsink and fan.

•Your Intel® Pentium® 4 LGA775 heatsink and fan assembly comes in a push-pin design and requires no tool to install.

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

2.4.4Uninstalling the CPU heatsink and fan assembly

To uninstall the CPU heatsink and fan:

1.Disconnect the CPU fan cable from the CPU_FAN connector on the motherboard.

2.Rotate each fastener counterclockwise.

3.Pull up two fasteners at a time in a diagonal sequence to disengage the heatsink and fan assembly from the motherboard.

•This chipset officially supports DDR2-800 MHz. With theASUS Super

Memspeed Technology, this motherboard natively supports up to

DDR2-1066 MHz. See the table below.

FSB	DDR2

1333	667
1066	1066*
1066	800
1066	667

•*If you install a DDR2-1066 memory module whose SPD is DDR2-800, make sure that you set the DRAM Frequency item in BIOS to

[DDR2-1066MHz]. See section 5.4.1 Jumperfree Configuration for details.

2.5.1Memory configurations

You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered non ECC DDR2

DIMMs into the DIMM sockets.

• You may install varying memory sizes in Channel A and 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.

•Always install DIMMs with the same CAS latency. For optimum compatibility, we recommend 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 install a 64-bit Windows OS when having 4GB or more memory installed on the motherboard.

Notes on memory limitations

• Due to chipset limitation, this motherboard can only support up to

8 GB on the operating systems listed below. You may install a maximum of 2 GB DIMMs on each slot.

64-bit

Windows® XP Professional x64 Edition

Windows® Vista x64 Edition

•Some old-version DDR2-800/667 DIMMs may not match Intel®’s On Die Termination (ODT) requirement and will automatically downgrade to run at DDR2-533. If this happens, contact your memory vendor to check the ODT value.

•Due to chipset limitation, DDR2-800 with CL=4 will be downgraded to run at DDR2-667 by default setting. If you want to operate with lower latency, adjust the memory timing manually.

•Due to chipset limitation, DDR2-667 with CL=3 will be downgraded to run at DDR2-533 by default setting. If you want to operate with lower latency, adjust the memory timing manually.
