1.4 Before 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 that lights up to indicate that the

system is ON, in sleep mode, or in soft-off mode. This is a reminder that you must

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.

1.5 Motherboard overview

Before you install the motherboard, study the configuration of your chassis to ensure that the

motherboard fits into it.

Ensure that you unplug the power cord before installing or removing the motherboard.

Failure to do so can cause you physical injury and damage motherboard components.

1.5.1 Placement direction

When installing the motherboard, ensure that you place it into the chassis in the correct

orientation. The edge with external ports goes to the rear part of the chassis as indicated in

the image below.

1.5.2 Screw holes

Place six screws into the holes indicated by circles to secure the motherboard to the chassis.

1.6 Central 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 Extreme / Pentium® D /

Pentium" 4 / Celeron® E1000 Series and 400 Series processors.

Unplug all power cables before installing the CPU.

Connect the chassis fan cable to the CHA_FAN connector to ensure system stability.

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

Authorization (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.

The motherboard supports Intel LGA775 processors with the Intel® Enhanced Intel
SpeedStep"1 Technology (EIST) and Hyper-Threading Technology.

1.6.1 Installing the CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

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.
