Safety information
Electrical safety
• To prevent electrical shock hazard, disconnect the power cable from
the electrical outlet before relocating the system.
• When adding or removing devices to or from the system, ensure
that the power cables for the devices are unplugged before the
signal cables are connected. If possible, disconnect all power
cables from the existing system before you add a device.
• Before connecting or removing signal cables from the motherboard,
ensure that all power cables are unplugged.
• Seek professional assistance before using an adapter or extension
cord. These devices could interrupt the grounding circuit.
• Make sure that your power supply is set to the correct voltage in
your area. If you are not sure about the voltage of the electrical
outlet you are using, contact your local power company.
• If the power supply is broken, do not try to fix it by yourself. Contact a
qualified service technician or your retailer.
Operation safety
• Before installing the motherboard and adding devices on it, carefully
read all the manuals that came with the package.
• Before using the product, make sure all cables are
correctly connected and the power cables are not damaged. If you
detect any damage, contact your dealer immediately.
• To avoid short circuits, keep paper clips, screws, and staples
away from connectors, slots, sockets and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the
product in any area where it may become wet.
• Place the product on a stable surface.
• If you encounter technical problems with the product, contact
a qualified service technician or your retailer.

introduction

1.1 Before you proceed
Take note of the following precautions before you install motherboard components or
change any motherboard settings.
• U n p l u g t h e p o w e r c o r d f r o m t h e w a l l s o c ke t b e f o r e t o u c h i n g a ny
component.
• 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 cord is detached from
the power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/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 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.
1-2 Chapter 1: Product introduction

1. Motherboard overview
Before you install the motherboard, study the configuration of your chassis to
ensure that the motherboard fits into it. Refer to the chassis documentation before
installing the motherboard.
M ake sur e to unp lu g t he p owe r c o r d b efo r e inst allin g o r r e m ov in g t he
motherboard. Failure to do so can cause you physical injury and damage
motherboard components.
1.2.1 Placement direction
When installing the motherboard, make sure 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.
1.2.2 Screw holes
Plac e eleven (11) screws into the holes indic ated by circles to secure the
motherboard to the chassis.
Do not overtighten the screws! Doing so can damage the motherboard.
Place this side towards
the rear of the chassis

1.3 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for the
Intel
®
Pentium
®
4 processor in the 775-land package.
• Your boxed Intel
®
Pentium
®
4 LGA775 processor package should
come with installation instructions for the CPU, heatsink, and the
retention mechanism. If the instructions in this section do not match
the CPU documentation, follow the latter.
• 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. Avalue will shoulder the
cost of repair only if the damage is shipment/transit-related.
• Keep the cap after installing the motherboard. Avalue 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.
1.3.1 Installing the 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.
1-6 Chapter 1: Product introduction

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.
3. Lift the load lever in the direction of
the arrow to a 135º angle.
4. L i f t t h e l o a d p l a t e w i t h y o u r

CPU!
Notes on Intel Hyper-Threading Technology
• This motherboard suppor ts Intel
®
Pentium
®
4 CPUs in the 775 -land
package with Hyper-Threading Technology.
• Hyper-Threading Technology is suppor ted under Windows
®
XP/2003
Server and Linux 2.4.x (kernel) and later versions only. Under Linux, use
the Hyper-Threading compiler to compile the code. If you are using any
other operating systems, disable the Hyper-Threading Technology item in
the BIOS to ensure system stability and performance.
• Installing Windows
®
XP Service Pack 1 or later version is recommended.
• Make sure to enable the Hyper-Threading Technology item in BIOS before
installing a supported operating system.
• For more information on Hyper-Threading Technology, visit www.intel.
com/info/hyperthreading.
To use the Hyper-Threading Technology on this motherboard:
1. Install an Intel
®
Pentium
®
4 CPU that supports Hyper-Threading Technology.
2. Power up the system and enter the BIOS Setup (see Chapter 2: BIOS
setup). Under the Advanced Menu, make sure that the item Hyper-Threading
Technology is set to Enabled. The item appears only if you installed a CPU
that supports Hyper-Threading Technology.
3. Reboot the computer.
1-8 Chapter 1: Product introduction

1.3.2 Installing the CPU heatsink and fan
The Intel
®
Pentium
®
4 LGA775 processor requires a specially designed heatsink
and fan assembly to ensure optimum thermal condition and performance.
• W h e n yo u b u y a b oxe d I nt e l
®
Pe nt i u m
®
4 p r o c e s s o r, t h e p a c k a g e
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 you have properly applied Thermal Interface Material to the CPU
heatsink or CPU before you install the heatsink and fan assembly.
Make sure that you have installed the motherboard to the chassis before you
install the CPU fan and heatsink assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, making sure that
the four fasteners match the holes
on the motherboard.

1.4 System memory
1.4.1 DIMM sockets location
The motherboard comes with four 240-pin Double Data Rate 2 (DDR2) Dual Inline
Memory Modules (DIMM) sockets.
The following figure illustrates the location of the sockets:
1.4.2 Memory Configurations
You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR2 DIMMs
into the DIMM sockets using the memory configurations in this section.
• For dual - channel c onf iguration, the total size of memor y module(s)
installed per channel must be the same (DIMM_A2 = DIMM_B2).
• A l w a y s i n s t a l l D I M M s w i t h t h e s a m e C A S l a t e n c y. F o r o p t i m u m
compatibility, it is recommended that you obtain memory modules from the
same vendor. Refer to the DDR2 Qualified Vendors List on the next page
for details.
• Due to chipset resource allocation, the system may detect less than 4 GB
system memory when you installed four 1 GB DDR2 memory modules.
• This motherboard does not support memory modules made up of 128 Mb
chips or double sided x16 memory modules.
