package. With 1333/1066/800MHz FSB, the Intel® Quad-core processor delivers
excellent multi-tasking and multi-media performance and provides gamers with
great gaming experience. It is one of the most powerful CPUs in the world.
Intel® Core™2 Processor Ready
This motherboard supports the latest Intel® Core™2 processor in the LGA775
package. With the new Intel® Core™ microarchitecture technology and
1333/1066/800MHz FSB, the Intel® Core™2 processor is designed to provide
powerful and energy efcient performance.
FSB 1600 support (O.C.)
ASUS’s exclusive overclocking design now unleashes the ultimate potential of the
Intel® Core™2 processor. With the new Intel 45nm micro-architecture technology
and FSB 1600 (O.C.) / 1333 / 1066 / 800 MHz, this motherboard allows you to
enjoy the latest technology supported by one of the most powerful and energy
efcient CPUs 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.

1-4 Chapter 1: Product introduction
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
specications.
DDR2 memory support
The motherboard supports DDR2 memory that features data transfer rates of
667/800/1066 (O.C.) 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 12.8 GB/s
(17.0 GB/s when overclocking 1066). Without restriction to the memory size across
the two channels, the motherboard allows you to install DIMMs with different
memory size and enjoy dual-channel feature at the same time. See page 1-18 for
details.
8-channel high denition audio
Enjoy high-quality sound system on your PC! The onboard 8-channel HD audio
(High Denition Audio, previously codenamed Azalia) CODEC enables high-quality
192KHz/24-bit audio output, jack-detect feature, which automatically detects and
identies what types of peripherals are plugged into the audio I/O jacks and noties
users of inappropriate connection, meaning there will be no more confusion of
Line-in, Line-out and Mic jacks. See pages 1-29, 1-34 and 2-25 for details.
Serial ATA 3Gb/s technology
This motherboard supports the next-generation hard drives based on the Serial
ATA (SATA) 3Gb/s storage specication, 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
1-32 for details.

ASUS P5KPL-C/1600 1-5
USB 2.0 technology
USB 2.0 is the latest connectivity standard for next generation components and
peripherals. Backwards compatible with current USB 1.1 peripherals, USB 2.0
delivers transfer speeds up to 40 times faster at 480Mb/s, for easy connectivity and
ultra-fast data transfers.
Gigabit LAN solution
The on-board LAN controller is a highly integrated Gigabit LAN controller. It
is enhanced with an ACPI management function to provide efcient power
management for advanced operating systems.
1.3.2 Innovative ASUS features
ASUS CrashFree BIOS3
The ASUS CrashFree BIOS 3 allows users to restore corrupted BIOS data from a
USB ash disk containing the BIOS le. See page 2-7 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 efcient operation. See page 2-31 for
details.
Fanless design
ASUS has devoted special efforts to address the thermal issues across the
motherboard, and most notably the areas that reside the CPU, power, Northbridge
and Southbridge. The heat sinks and strategic board layout were tailor made to
dissipate heat in the most efcient manner. With the addition of Stack Cool 2, users
can even overclock without a noisy, bulky fan.

1-6 Chapter 1: Product introduction
ASUS EZ Flash2
EZ Flash 2 is a user-friendly BIOS update utility. Simply press the predened
hotkey to launch the utility and update the BIOS without entering the OS. Update
your BIOS easily without preparing a bootable diskette or using an OS-based ash
utility. See page 2-4 and 2-36 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 MyLogo2™
This feature allows you to convert your favorite photo into a 256-color boot logo for
a more colorful and vivid image on your screen. See page 2-33 for details.
Green ASUS
This 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/packaging to safeguard
consumers’ health while minimizing the impact on the environment.

ASUS P5KPL-C/1600 1-7
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.
1.4 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.

1.5 Motherboard overview
Before you install the motherboard, study the conguration of your chassis to
ensure that the motherboard ts into it.
1.5.1 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.
Place this side towards
the rear of the chassis
Do not overtighten the screws! Doing so can damage the motherboard.
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.
1.5.2 Screw holes
Place six (6) screws into the holes indicated by circles to secure the motherboard
to the chassis.
