AthlonTM Processors
The AMD AthlonTM is a seventh-generation micro architecture with an integrated
L2 cache, which is powerful enough to support the bandwidth requirements of a
large range of applications, hardware, graphics, and memory technologies. These
processors implement advanced design techniques such as:
Socket A (PGA 462
266/333MHz system interface based on the Alpha EV6 bus protocol.
Three out-of-order, superscalar, pipelined Multimedia Units.
Three out-of-order, superscaler, pipelined Integer Units.
Fixed-sized internal instruction formats (MacroOPs .
72-entry Instruction Control Units.
AMD enhanced 3DNow! technology
L1 and L2 caches.
Dynamic branch prediction.
Socket A is the name for AMDs new socketed interface designed to support AMD
AthlonTM processors. This innovation is made possible by integrating the L2 cache
memory on chip with the processor. Socket A will help enable smaller enclosures,
and ultimately result in a wider variety of solutions in the market.
The AthlonTM processors in the Socket A format continue to deliver the ultimate
performance for cutting-edge applications. They bring to desktop systems running
industry-standard x86 software superscalar RISC performance. Being provided in
the Socket A format they are the worlds most powerful x86 processors. They easily
deliver the highest integer, floating-point, and 3D multimedia performance for
applications running on x86 platforms around.
It features full-speed, on-chip cache memory, a 266/333MHz front side system bus,
and enhanced 3DNow! technology. The AMD AthlonTM processor is targeted at
the performance segment, and as such will have more cache memory and higher
clock speeds.

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 a LAN chipset. It allows the mainboard to
connect to a local area network by means of a network hub.
Serial ATA (Optional)
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.

Mainboard Form-Factor
This board is designed with M-ATX form factor - the latest industry standard for
chassis design. The M-ATX form factor is essentially a Baby-AT baseboard
rotated 90 degrees within the chassis enclosure and a new mounting configura-
tion 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. M-
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 5VSBs spe ifi ation printed on the power supplys
outer ase.
Note: The board requires a minimum of 250 Watt power supply to operate. Your
system onfiguration (amount of memory, add-in ards, peripherals, et .) may
ex eed the minimum power requirement but to ensure that adequate power is
provided, use a 300 Watt (or greater) power supply.
I/O Shield Connector
The board is equipped with an I/O back panel (Figure 3 . Ensure that your computer
case has the appropriate I/O cutout.
