Product
introduction
This chapter describes the motherboard
features and the new technologies
it supports.

1-2 Chapter 1: Product introduction
1.1 Welcome!
Thank you for b uying a n ASUS®P5LD2-FM/DH/VP motherboard!
The motherboard delivers a host of new features and latest technologies,
making it another standout in the long line of ASUS quality motherboards!
Before you start installing the motherboard, and hardware devices on it,
check the items in your package with the list below.
1.2 Special features
1.2.1 Product highlights
Latest processor technology
The motherboard comes with a 775-pin surface mount Land Grid Array
(LGA) socket designed for the Intel®Pentium®D, Intel®Pentium®4 or Intel®
Celeron®processor in the 775-land package. The motherboard supports
the Intel® Pentium® 4 or Intel®Pentium®D processor with 1066/800/533
MHz Front Side Bus (FSB). The motherboard also supports the Intel®
Hyper-Threading Technology and is fully compatible with Intel®PCG
06/05B/05A processors. See page 1-8 for details.
Intel®Dual-Core Technology CPU support
The motherboard supports dual-core processors containing two physical
CPU cores with dedicated L2 caches to meet demands for more powerful
processing. See page 1-8 for details.

ASUS P5LD2-FM/DH/VP 1-3
DDR2 memory support
The motherboard supports DDR2 memory which features data transfer rates
of 667 MHz (FSB 800) or 533 MHz (FSB 1066/800) 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 10.7 GB/s.
PCI Express™ interfa ce
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 specications. See page 1-20 for details.
64-bit CPU support
The motherboard supports 64-bit processors that provides
high-performance computing and faster memory access required for
memory and data intensive applications.
Serial ATA technology
The motherboard supports the Serial ATA technology through the Serial ATA
interfaces and the Intel®ICH7DH chipset. The SATA specication allows
for thinner, more exible cables with lower pin count, reduced voltage
requirement, and up to 300 MB/s data transfer rate.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored by the ASIC (integrated in the Winbond
Super I/O) to prevent overheating and damage. The system fan rotations
per minute (RPM) is monitored for timely failure detection. The ASIC
monitors the voltage levels to ensure stable supply of current for critical
components. See pages 2-32 and 2-33 for details.

1-4 Chapter 1: Product introduction
8-channel high definition audio
The onboard Realtek®ALC888 8-channel high-denition audio CODEC provides 192 KHz/
24-bit audio output, jack-sensing and restasking functions. With the 8-channel audio
ports and S/PDIF interfaces, you can connect your computer to home theater decoders
to produce crystal-clear digital audio.
S/PDIF digital sound ready
The motherboard supports the S/PDIF Out function through the S/PDIF interfaces at
midboard. The S/PDIF technology turns your computer into a high-end entertainment
system with digital connectivity to powerful audio and speaker systems. See page 1-27 for
details.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored by the ASIC (integrated in the Winbond Super I/O)
to prevent overheating and damage. The system fan rotations per minute (RPM) is
monitored for timely failure detection. The ASIC monitors the voltage levels to ensure
stable supply of current for critical components. See pages 2-32 and 2-33 for details.

ASUS P5LD2-FM/DH/VP 1-5
1.3 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.
• Befo re you install or re m ove any component, ensure
that the AT X 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.

1-6 Chapter 1: Product introduction
1.4 Motherboard overview
Before you install the motherboard, study the conguration 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.
Do not overtighten the screws! Doing so can damage the motherboard.
1.4.1 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.
1.4.2 Screw holes
Place eight (8) screws into the holes indicated by circles to secure the
motherboard to the chassis.
Place this side towards
the rear of the chassis

1-8 Chapter 1: Product introduction
1.5.1 Installling the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
1.5 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, fan and heatsink
assembly. 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 pins are not bent. Contact your
retailer immediately if the PnP cap is missing, or if you see any
damage to the PnP cap/socket pins/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 pins
resulting from incorrect CPU installation/removal, or misplacement/
loss/incorrect removal of the PnP cap.
Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.
