1.3 .1 Pro du ct hi gh li ght s
Lat e st pro c es s or t ec h nol o gy
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 2-6, A-1 and A-2 for details.
Int e l® Co r e™ 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.
Int e l® 65 n m D ual - Cor e C P U s upp o rt
This motherboard support Intel® Prescott, Intel® Smitheld, Intel® Cedarmill,
Intel® Conroe, Intel® Conroe L or Intel® Presler processors built on the 65nanometer (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- b it CPU sup por t
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.
ASUS P5LD2-X 1-3
DDR 2 m e mor y s u ppo r t
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.
Hig h D e fin i ti o n A u di o
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.
Ser i al ATA 3. 0 Gb / s t ech n olo gy
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 2-23 for details.
S/P D IF dig i ta l so u nd rea d y
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 2-22 for details.
PCI Ex p res s ™ i nte r fa c e
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 2-18 for details.
USB 2.0 te c hno log y
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 2-22 and 2-25 for details.
1-4 Chapter 1: Product introduction
Gre e n A SUS
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 Inn ov at ive A SU S f ea tu res
ASU S C r ash F re e BI O S 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.
ASU S Q - Fan te c hno l og y
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.
ASU S E Z Fl a sh
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. (CP U P a ram e te r Re c al l )
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. See page 2-19 for details.
ASU S C P U L o ck Fre e
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.
ASUS P5LD2-X 1-5
ASU S M y Log o ™
The new feature present in the motherboard allows you to personalize and
add style to your system with customizable boot logos. See page 5-6 for
details.

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
CPU Socket 775
The motherboard comes with a surface mount LGA775 socket designed
for the Intel® Prescott/Smitheld/Cedarmill/ Conroe/Conroe L/Presler
processor in the 775-land package
•
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.
