Introducing the Mainboard

Congratulations on purchasing the K7S5A2 mainboard. The

K7S5A2 mainboard is an ATX mainboard that uses a 4-layer

printed circuit board and measures 244 mm x 304 mm. The

mainboard features a Socket 462 that accommodates AMD

Athlon/Duron processors supporting frontside bus (FSB)

speeds up to 133 MHz.

The K7S5A2 incorporates the SiS735 Northbridge and South-

bridge chipsets which combine support for the new high-

bandwidth Double Data Rate (DDR) 266 SDRAM, and the AC

97 audio codec.

Note: SDRAM provides 800 MBps or 1 GBps data trans-

fer depending on whether the bus is 100 MHz or

133 MHz. Double Data Rate SDRAM (DDR

SDRAM) doubles the rate to 1.6 GBps or 2.1 GBps

by transferring data on both the rising and falling

edges of the clock. DDR SDRAM uses additional

power and ground lines and requires 184-pin DIMM

modules rather than the 168-pin DIMMs used by

SDRAM.

K7S5A2 V1.0

Processor The K7S5A2 mainboard uses an AMD 462-pin

Socket A that has the following features:

•Supports 100/133 MHz frontside bus (FSB)

•Accommodates AMD Athlon/Duron processors

Chipset The SiS735 Northbridge and Southbridge chipsets

are based on an innovative and scalable architec-

ture with proven reliability and performance. A few

of the chipset’s advanced features are:

•A low 2.5-volt DDR266 SDRAM power con-

sumption which makes it an excellent solution

for notebooks and desktops with a small foot-

•Support for a 4xAGP interface providing vivid

3D graphics and video performance

•An ATA 100 interface on the chipset, which

helps boost system performance by providing

a high-speed connection to ATA 100 Hard

Disk Drives, delivering maximum sustained

data transfer rates of 100 MB/sec

•Built-in multithreaded I/O link used to enhance

performance, providing enough I/O bandwidth

for throughput up to 1.2 GB/s

Additional key features include support for six

USB ports, an AC 97 link for audio and modem,

hardware monitoring, and ACPI/OnNow power

management.

Memory The mainboard supports both DDR SDRAM and

SDR SDRAM. It accommodates two unbuffered

2.5V 184 pin slots and two unbuffered 3.3V 168

pin slots. Each slot can support up to 512 MB with

a total maximum capacity of 1.0 GB.

VGA The K7S5A2 includes a 4xAGP slot that provides

four times the bandwidth of the original AGP

specification. AGP technology provides a direct

connection between the graphics sub-system and

the processor so that the graphics do not have to

compete for processor time with other devices on

the PCI bus.

K7S5A2 V1.0

AC 97 Audio

Codec The AC 97 Audio codec is compliant with the AC

97 2.1 specification, and supports 18-bit ADC

(Analog Digital Converter) and DAC (Digital Ana-

log Converter) resolution as well as 18-bit stereo

full-duplex codec with independent and variable

sampling rates. Further features include support

for four analog line-level stereo inputs.

Expansion

Options The mainboard comes with the following expan-

sion options:

•Five 32-bit PCI slots

•An 4xAGP slot

•A Communications Network Riser (CNR) slot

(AC97 interface only)

•Two IDE channels and a floppy disk drive in-

terface

The K7S5A2 supports Ultra DMA bus mastering

with transfer rates of 33/66/100 MB/sec.

Integrated I/O The mainboard has a full set of I/O ports and con-

nectors:

•Two PS/2 ports for mouse and keyboard

•Two serial ports

•One parallel port

•One MIDI/game port

•Two USB ports

•Audio jacks for microphone, line-in and line-

out

BIOS

Firmware This mainboard uses Award BIOS that enables

users to configure many system features including

the following:

•Power management

•Wake-up alarms

•CPU parameters

•CPU and memory timing

The firmware can also be used to set parameters

for different processor clock speeds.
