ASUS P5KPL SE 1-3
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
1600 (overclocking)/1333/1066/800 MHz FSB, Intel®Core™2 processor is
designed to provide powerful and energy efcient performance.
DDR2 memory support
The motherboard supports DDR2 memory that features data transfer rates of
1066 (overclocking)/800/667MHz 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 1-15 for
details.
Serial ATA 3 Gb/s technology
This motherboard supports the next-generation hard drives based on the Serial
ATA (SATA) 3 Gb/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
1-29 for details.
High Denition Audio
Enjoy high-end sound quality on your PC! The onboard 6-channel HD audio (High
Denition Audio, previously codenamed Azalia) CODEC enables high-quality
192KHz/24-bit audio output, jack-detect feature.
Gigabit LAN solution
PCI Express Gb LAN controller delivers transfer speeds up to ten times faster than
conventional 10/100/1000 Ethernet connections. Gigabit LAN is the networking
standard for the early future and is ideal for handling large amounts of data such
as video, audio, and voice. See page 1-25 for details.

1-4 Chapter 1: Product introduction
1.3.2 ASUS Special features
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 2-30 for
details.
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 2-32 for details.
ASUS EZ Flash 2
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 for details.
ASUS CrashFree BIOS 3
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.
AI NET 2
AI NET 2 is a BIOS-based diagnostic tool that detects and reports Ethernet cable
faults and shorts. With this utility, you can easily monitor the condition of the
Ethernet cable(s) connected to the Marvell®LAN (RJ-45) port. During the bootup
process, AI NET 2 immediately diagnoses the LAN cable and reports shorts and
faults up to 100 meters at 1 meter accuracy. See page 2-36 for details.
1.3.3 ASUS Overclocking features
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.

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
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 that 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.

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

1.6 Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for the
Intel®Core™2 Quad/Core™2 Extreme/Core™2 Duo/Pentium®Extreme/
Pentium®D/Pentium®4/Celeron®Sequence Processors.
• 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.
• Ensure that the AC power is off before you install the CPU.
• If installing a dual-core CPU, connect the chassis fan cable to the chassis
fan connector to ensure system stability.
1.6.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
Before installing the CPU, ensure that the cam box is facing towards you and
the load lever is on your left.
