1.3 Special features
1.3.1 Product highlights
Latest processor technology
The motherboard comes with a 775-pin surface mount Land Grid Array
(LGA) socket designed for the Intel®Pentium®4 processor in the 775-land
package. The motherboard supports the Intel® Pentium® 4 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®
05B/05A or 04B/04A processors. See page 2-6 for details.
Intel®Core™ 2™ 22
The motherboard supports the latest IntelIntel®CoreTM 2 processor in the
LGA775 package. With the new IntelIntel®CoreTM microarchitecture technology
and 1066/800MHz FSB, Intel®CoreTM 2 processor is one of teh most
powerful and energy efcient CPU in the world..
Enhanced Intel SpeedStep®Technology (EIST)
The Enhanced Intel SpeedStep®Technology (EIST) intelligently manages
the CPU resources by automatically adjusting the CPU voltage and core
frequency depending on the CPU loading and system speed or power
requirement. See page 4-25 and the Appendix for details.
Intel®945P chipset
The Intel®945P Memory Controller Hub (MCH) and the ICH7 I/O controller
hub provide the vital interfaces for the motherboard. The MCH provides
support for Intel®processor, dual-channel memory, and PCI Express
interfaces.
The Intel® ICH7 Southbridge represents the seventh generation I/O
controller hub that provides the interface for storage, I/O, PCI Express, and
6‑channel high denition audio system.
DDR2 memory support
The motherboard supports DDR2 memory which 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
to 10.7 GB/s. See pages 2-13 to 2-16 for details.

ASUS P5L 1394 1-3
Serial ATA technology
The motherboard supports the Serial ATA technology through the Serial
ATA interfaces and Intel® ICH7 southbridge. 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. See page 2-25 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 specications. See page 2‑19 for details.
6-channel high definition audio
Onboard is the Realtek® High Denition 6‑channel audio CODEC. This CODEC
is fully-compliant with Intel® High Denition Audio standard (192KHz, 24‑bit
audio). With the CODEC, 6-channel audio ports, and S/PDIF interfaces, you
can connect your computer to home theater decoders to produce crystal-
clear digital audio.
The Realtek® High Denition audio CODEC comes with a software application
that features jack detection to monitor the plugging status of each jack,
impedance sensing to determine audio device classes, and pre‑dened
equalizaion for various audio devices. See pages 2-22 to 2-23, and 5-10 for
details.
S/PDIF digital sound ready
The motherboard supports the S/PDIF technology through the coaxial
S/PDIF Out port 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 2-23 for details.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0
specication, dramatically increasing the connection speed from the
12 Mbps bandwidth on USB 1.1 to a faster 480 Mbps on USB 2.0. USB 2.0
is backward compatible with USB 1.1. See pages 2-23 and 2-27 for details.

1-4 Chapter 1: Product introduction
1.3.2 Innovative ASUS features
Fanless Design
The ASUS fanless design allows multi‑directional heat ow from major
thermal sources in the motherboard to lower overall system temperature,
resulting in quieter operation and longer system life.
Precision Tweaker
This feature allows you to ne‑tune the CPU/memory voltage and gradually
increase the Front Side Bus (FSB) and PCI Express frequency to achieve
maximum system performance. See pages 4-20 to 4-22 for details.
CrashFree BIOS
This feature allows you to restore the original BIOS data from the support CD
in case 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 efcient operation.
See pages 4-33 for details.
ASUS MyLogo™
This new feature present in the motherboard allows you to personalize and
add style to your system with customizable boot logos. See page 5-8 for
details.
Gigabit LAN solution
The motherboard comes with a PCI Express Gigabit LAN controller to
provide a total solution for your networking needs. The Gigabit LAN
controller uses the PCI Express segment to provide faster data bandwidth.
See pages 2-22 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 4-33 and 4-34 for details.
