Product highlights
Latest processor technology
The motherboard comes with a 775-pin surface mount Land Grid Array (LGA)
socket designed for the Intel® Prescott, Intel® Smitheld, Intel® Cedarmill, Intel®
Conroe, Intel® Conroe L or Intel® Presler processor in the 775-land package. The
motherboard supports the processors with 1066 / 800 / 533 MHz Front Side Bus
(FSB). The motherboard also supports the Intel® Hyper-Threading Technology and
Enhanced Intel® SpeedStep Technology (EIST). See pages 2-5, A-1 and A-2 for
details.
Intel® Core™2
This motherboard supports the latest Intel® Core™2 processor in the LGA775
package. With the new Intel® Core™ microarchitecture technology and 1066 /
800 / 533 MHz FSB, Intel® Core™2 processor is one of the most powerful and
energy efcient CPU in the world.
64-bit CPU support
64-bit computing, the next generation technology to replace current 32-bit
architecture, delivers advanced system performance, faster memory access and
increased productivity. This motherboard provides excellent compatibility and
exibility by supporting either 64-bit or 32-bit architecture.
DDR2 memory support
The motherboard supports DDR2 memory that features data transfer rates of 667 /
533 MHz to meet the higher bandwidth requirements of the latest 3D graphics,
multimedia, and Internet applications. The dual-channel DDR2 architecture
doubles the bandwidth of your system memory to boost system performance,
eliminating bottlenecks with peak bandwidths of up to 10.6 GB/s. See page 2-11
for details.
ASUS P5LD2-C/IPAT 1-3
High Denition Audio
The onboard 6-channel ALC662 High Denition audio CODEC enables high-quality
audio which automatically detects peripherals are plugged into the audio I/O jacks.
ALC662 also supports Windows® Vista Premium. See pages 2-22 for details.
Serial ATA 3.0 Gb/s technology
This motherboard supports the next-generation hard drives based on the Serial
ATA (SATA) 3Gb/s storage specication, delivering enhanced scalability and
doubling the bus bandwidth for high-speed data retrieval and saves. Easily backup
photos, videos and other entertainment contents to external devices. See page
2-25 for details.
PCI Express™ interface
The motherboard fully supports PCI Express, the latest I/O interconnect technology
that speeds up the PCI bus. PCI Express features point-to-point serial
interconnections between devices and allows higher clockspeeds by carrying data
in packets. This high speed interface is software compatible with existing PCI
specications. See page 2-19 for details.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0 specication,
dramatically increasing the connection speed from the 12 Mbps bandwidth on USB
1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1.
See pages 2-23 and 2-26 for details.
Green ASUS
The motherboard and its packaging comply with the European Union’s Restriction
on the use of Hazardous Substances (RoHS). This is in line with the ASUS
vision of creating environment-friendly and recyclable products and packaging to
safeguard consumers’ health while minimizing the impact on the environment.

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.
2.1 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.
• Use a grounded wrist strap or touch a safely grounded object or to
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.

2.2 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to
ensure that the motherboard ts into it.
Ensure to unplug the power cord before installing or removing the motherboard.
Failure to do so can cause you physical injury and damage motherboard
components.
Do not overtighten the screws! Doing so can damage the motherboard.
2.2.1 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.
2.2.2 Screw holes
Place seven (7) screws into the holes indicated by circles to secure the
motherboard to the chassis.
Place this side towards
the rear of the chassis

2.3.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
2.3 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for the
Intel® Core
TM
2 Duo / CoreTM 2 Extreme / Pentium® D / Pentium® 4 / Celeron® processor in
the 775-land package
Before installing the CPU, ensure that the cam box is facing towards you and
the load lever is on your left.
•
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® CoreTM 2 Duo / CoreTM 2 Extreme / Pentium®
D / Pentium® 4 / Celeron® LGA775 processors with the Intel® Enhanced Intel
SpeedStep® Technology (EIST) and Hyper-Threading Technology. Refer to the

2.3.2 Installing the CPU heatsink and fan
The Intel® CoreTM 2 Duo / CoreTM 2 Extreme / Pentium® D / Pentium® 4 / Celeron
®
LGA775 processor requires a specially designed heatsink and fan assembly to
ensure optimum thermal condition and performance.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, ensuring that the
four fasteners match the holes on
the motherboard.

•
When you buy a boxed Intel® CoreTM 2 Duo / CoreTM 2 Extreme / Pentium®
D / Pentium® 4 / Celeron® processor, the package
includes the CPU fan and heatsink assembly. If you buy a CPU separately,
ensure that you use only Intel®-certied multi-directional heatsink and fan.
•
Your Intel® CoreTM 2 Duo / CoreTM 2 Extreme / Pentium® D / Pentium® 4 /
Celeron® 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, ensure that
you have properly applied Thermal Interface Material to the CPU heatsink
or CPU before you install the heatsink and fan assembly.
Ensure that you have installed the motherboard to the chassis before you install
the CPU fan and heatsink assembly.
Ensure to orient each fastener with the narrow end of the groove pointing
outward. (The photo shows the groove shaded for emphasis.)
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.
2. Push down two fasteners at a time in
a diagonal sequence to secure the
heatsink and fan assembly in place.
