AthlonTM 64 Processor
The AMD AthlonTM 64 (ClawHammer processor family is designed to support
performance desktop. It provides a high performance HyperTransportTM link to I/O,
as well as a single 64-bit high-performance DDR memory controller. Main key
features such as:
AMD64 technology enables the industry to advance software development
on all fronts, with x86 compatibility, while providing the capability of deliver-
ing 64-bit technology benefits.
HyperTransport technology helps reduces the number of buses in a system,
which can reduces system bottlenecks and enable todays faster micropro-
cessors to use system memory more efficiently in high-end multiprocessor
systems.
The memory controller provides a programmable interface to a variety of
standard DDR SDRAM DIMM configuration.
For more information about all the new features AthlonTM 64 Processor deliver, check out
the AMD website at http://www amd com
Chipset Overview
The board is designed with VIA chipset, K8T800 as North Bridge and VT8237 as
South Bridge, providing a feature rich and scalable platform. The K8T800 North
Bridge is designed with an ultra fast HyperTransport link to the AthlonTM 64 and
comes equipped with AGP 8X features for VGA card expansion.
The K8T800 North Bridge connects to the VT8237 South Bridge through the fast
Ultra V-Link connection at 1.06GB/s. With support for two Serial ATA channels at
150MB/s bandwidth, integrated RAID (0, 1, 0+1 & JBOD capability as well as up to
eight USB 2.0 ports, the VT8237 offers the highest possible peripheral performance
for professional users. To extend flexibility to the system integrator, the VT8237
features dual channel Parallel ATA-133 allowing for configurations that leverage the
existing technology standard. Additional features include a VIA MAC for 10/
100Mbps Fast Ethernet, integrated PCI support.

Introduction
Page 1-3
Accelerated Graphics Port (AGP)
The AGP slot on the board is compliant with the new AGP 3.0 specification. This
new specification enhances the functionality of the original AGP specification by
allowing 8X data transfers ( 8 data samples per clock resulting in maximum band-
width of 2.1GB/s. In addition, it defines 1.5 volt power supply operation. Complying
with this specification, this board supports external AGP-8X/4X cards with Fast
Write Transactions. Only 1.5V AGP cards are supported.
Ultra ATA/66/100/133
This mainboard provides two independent ATA133 IDE controllers, supporting
standard programmable input/output (PIO and Direct Memory Access (DMA
mode operations, as well as UltraDMA-133/100/66/33 standards for a maximum data
transfer rate of 133MB/sec per channel.
Hardware Monitoring
Hardware monitoring enables you to monitor various aspects of the system operation
and status. The features include CPU temperature, voltage and fan speed in RPMs.
LAN (Optional)
This mainboard is optionally mounted with LAN chipset. It allows the mainboard to
connect to a local area network by means of a network hub.
Serial ATA
The evolutionary serial ATA interface replaces the standard parallel ATA physical
storage interface. The serial ATA specification provides scalability and allows
future enhancements to the computing platform. Serial technology overcomes
performance limits of parallel interface architecture, meeting the escalating need for
faster data throughput in servers and storage devices.
Serial ATA is completely software compatible with parallel ATA, requiring no
modification to your operating system. The serial ATA interface cable requires lower
voltages and uses smaller cable connectors, providing ease of installation. You can
easily upgrade storage devices that are compatible with the serial ATA interface
specification.

Introduction
Page 1-4
Mainboard Form-Factor
This board is designed with ATX form factor - the latest industry standard for
chassis design. The ATX form factor is essentially a Baby-AT baseboard rotated
90 degrees within the chassis enclosure and a new mounting configuration for
the power supply. With these changes the processor is relocated away from the
expansion slots, allowing them all to hold full length add-in cards. ATX defines a
double height aperture to the rear of the chassis which can be used to host a
wide range of onboard I/O. Only the size and position of this aperture is defined,
allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output,
joystick, modem, LAN, audio, etc. to systems. This will help systems integrators
differentiate their products in the marketplace, and better meet your needs.
 By integrating more I/O down onto the board and better positioning the hard
drive and floppy connectors, material cost of cables and add-in cards are
reduced.
 By reducing the number of cables and components in the system, manufac-
turing time and inventory holding costs are reduced and reliability will
increase.
 By using an optimized power supply, it's possible to reduce cooling costs
and lower acoustical noise. An ATX power supply, which has a side-
mounted fan, allows direct cooling of the processor and add-in cards making
a secondary fan or active heatsink unnecessary in most system applications.

Power-On/Off (Remote)
This board has a 20-pin ATX power supply connector (Figure 4 . For power
supplies that support the Remote On/Off feature, this should be connected to the
mainboard front panel PW_ON connector for the computer power On/Off button.
This board has been designed with Soft Off" function. You can turn off the system
in two ways: by pressing the front panel power On/Off button or using the "Soft
Off" function that can be controlled by an operating system such as Windows®XP/
ME/2000/98.
Note: For maintaining the DDR SDRAM power during STR (ACPI S3) fun tion, it is strongly
re ommended to use power supplies that have a +5VSB urrent of (>=) 2A. Please he k the
5VSBs spe ifi ation printed on the power supplys outer ase.
Note: The board requires a minimum of 250 Watt power supply to operate. Your system onfigura-
tion (amount of memory, add-in ards, peripherals, et .) may ex eed this minimum power
requirement. To ensure that adequate power is provided, use a 300 Watt (or higher) power
supply.
I/O Shield Connector
The I/O back panel for this mainboard is shown below (Figure 3 . When installing
the mainboard into the computer case, use the bundled I/O shield to protect this
back panel.
