1-2 Chapter 1: Product introduction
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/Celeron®/Pentium®
D/Pentium®Processor Extreme Edition in the 775-land package 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 and 04B/04A processors. See page 2-7 for details.
Intel®65nm Dual-Core CPU support
This motherboard supports Intel®Pentium®D/Pentium®4/Celeron®
dual-core processors built on the 65-nanometer (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. Intel®’s 65nm process 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. This motherboard also supports Intel® next
generation Core™2 Duo CPU. This motherboard supports the latest
Intel® Core™2 processors in LGA775 package. With new Intel® Core™
microarchitecture technology and 1066/800 MHz FSB, Intel® Core™2
processor is one of the most powerful and enrgy-efcient CPUs in the
world.
Intel®975X Express/ICH7R chipset
The Intel®975X Express Memory Controller Hub (MCH) and the ICH7R I/O
controller hub provide the vital interfaces for the motherboard. The Intel®
975X Express is the latest chipset designed to support Dual PCI Express
graphics, along with the maximum 8 GB dual-channel DDR2 800/667/533
MHz, 1066/800/533 FSB, and dual-core CPU. The MCH also supports the
Intel®Memory Pipeline Technology (MPT) that boosts system performance.
The Intel® ICH7R Southbridge integrates four Serial ATA I/II connectors
enabled through the Serial ATA 3 Gb/s RAID controller to ensure data
security and enable powerful multi-task processing.

ASUS P5WDG2 WS Professional/P5WDG2 WS PRO/WiFi-AP 1-3
Intel®Memory Pipeline Technology (MPT)
The Intel®MPT increases system-level and standard operating performance
by optimizing memory access between CPU and system memory.
Intel®EM64T
The motherboard supports Intel®Pentium®4 CPUs with the Intel®EM64T
(Extended Memory 64 Technology). The Intel®EM64T feature allows your
computer to run on 64-bit operating systems and access larger amounts of
system memory for faster and more efcient computing. See the Appendix
for details.
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 4-26 and the Appendix for details.
DDR2 memory support
The motherboard supports DDR2 memory, which features data transfer
rates of 800/667/533 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 page 2-14 for details.
Serial ATA I/II technology
The motherboard supports the Serial ATA 3 Gb/s technology through the
Serial ATA interfaces and the Intel®975X Express MCH chipset. The Serial
ATA 3 Gb/s specication provides twice the bandwidth of the current
Serial ATA products with a host of new features, including Native Command
Queuing (NCQ), Power Management (PM) Implementation Algorithm, and
Hot Swap. Serial ATA allows thinner, more exible cables with lower pin
count and reduced voltage requirements. See pages 2-35 and 2-36 for
details.

1-4 Chapter 1: Product introduction
8-channel high definition audio
Onboard is the ADI AD1988B High Denition Audio 8-channel audio CODEC.
This CODEC is fully-compliant with Intel® High Denition Audio standard
(192 KHz, 24-bit audio). With the CODEC, 8-channel audio ports, and S/
PDIF interfaces, you can connect your computer to home theater decoders
to produce crystal-clear digital audio.
IEEE 1394a support
The motherboard supports the IEEE 1394a interface that provides
high-speed and exible PC connectivity to a wide range of peripherals
and devices compliant to IEEE 1394a standards. The IEEE 1394a
interface allows up to 400 Mbps transfer rates through simple , low-
cost, high-bandwidth asynchronous (real-time) data interfacing between
computers, peripherals, and consumer electronic devices such as
camcorders, VCRs, printers, TVs, and digital cameras. See pages 2-33 and
2-38 for details.
S/PDIF digital sound ready
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 2-33 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 2-23 for details.
PCI-X®interface
The motherboard supports PCI-X, the new and improved version of the
previous PCI standard. PCI-X offers faster data transfers and enhanced
system reliability with ECC automatic single-bit error recovery and double-
bit error detection. PCI-X, which is backward-compatible with PCI-based
hardware and software, enables users to keep pace with upcoming
advances in high-bandwidth, business-critical applications such as Fiber
Channel, RAID, InniBrand™ Architecture, and iSCSI. See page 2-23 for
details.
