This motherboard support Intel® Prescott, Intel® Smitheld, Intel® Cedarmill, Intel®
Conroe, Intel® Conroe L or Intel® Presler processors built on the 65-nanometer
(nm) process technology with copper interconnect. Dual-core processors contain
two physical CPU cores with dedicated L2 caches to meet demands for more
powerful processing. The 65nm process of Intel® is the most advanced chip
manufacturing technology, delivering breakthrough performance, enhanced media
experience, and low power consumption. Intel® 65nm dual-core processors utilize
the latest package technologies for a thinner, lighter design without compromising
performance.
64 - bit C PU su ppo rt
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.
1-2Chapter 1: Product introduction
DDR2 memory support
The motherboard supports DDR2 memory that features data transfer rates of
667/533/400 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 to10.6 GB/s. See
page 2-13 for details.
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 2-23 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.
S/PDIF digital sound ready
The motherboard supports the S/PDIF technology through the S/PDIF interfaces
on the rear panel. The S/PDIF technology turns your computer into a high-end
entertainment system with digital connectivity to powerful audio and speaker
systems. See page 2-24 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 2-20 for details.
US B 2. 0 tec hn olo gy
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 2-24 and 2-27 for details.
ASUS P5LD2-X/13331-3
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.
1.3.2 Innovative ASUS features
ASUS CrashFree BIOS 2
This feature allows you to restore the original BIOS data from the support CD in
case when the BIOS codes and data are corrupted. This protection eliminates the
need to buy a replacement ROM chip. See page 4-5 for details.
ASUS Q-Fan technology
The ASUS Q-Fan technology smartly adjusts the fan speeds according to the
system loading to ensure quiet, cool, and efcient operation. See page 4-30 for
details.
ASUS EZ Flash
With the ASUS EZ Flash, you can easily update the system BIOS even before
loading the operating system. No need to use a DOS-based utility or boot from a
oppy disk. See page 4-7 for details.
C.P.R. (CPU Parameter Recall)
The C.P.R. feature of the motherboard BIOS allows automatic re-setting to the
BIOS default settings in case the system hangs due to overclocking. When the
system hangs due to overclocking, C.P.R. eliminates the need to open the system
chassis and clear the RTC data. Simply shut down and reboot the system, and the
BIOS automatically restores the CPU default setting for each parameter.
ASUS CPU Lock Free
This feature allows you to adjust the CPU multiplier to 14x. Setting the appropriate
BIOS setting automatically reduces the CPU multiplier value for more exibility
when increasing external FSB.

2.1 Before you proceed ..................................................................... 2-1
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.
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.

P5LD2-X/1333
2.2 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to
ensure that the motherboard ts into it.
Make sure to unplug the power cord before installing or removing the
motherboard. Failure to do so can cause you physical injury and damage
motherboard components.
2.2.1 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.
2.2.2 Screw holes
Place seven (7) screws into the holes indicated 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

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
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.
2.3.1 Installing the CPU
