Processor
The mainboard uses an AMD 462-pin Socket A that supports
133/166 MHz frontside bus (FSB).
Chipset
The SiS746 and SiS963/963L chipsets are based on an inno-
vative and scalable architecture with proven reliability and
performance. A few of the chipset’s advanced features are:
•
Supports AMD Socket A CPU: 133/166 MHz
•
Synchronous/Asynchronous Host-t-DRAM timing:
133/200, 133/266, 133/333, 166/266, 166/333
•
Supports 200/266/333 DDR SDRAM
•
Supports up to 2 unbuffered DIMM DDR333 or up to 3
unbuffered double-sided DIMM DDR266/200
•
AGP v3.0 Compliant
•
Bi-directional 16 bit data bus
•
1 GB/s performance in 133MHz x 4 mode
•
PCI 2.2 Specification Compliance
•
Integrated Multithreaded I/O Link Mastering with Read
Pipelined Streaming
•
Supports Enhanced Software and Automatic schemes to
access PHY registers
•
Supports Ultra DMA 33/66/100/133
•
USB v2.0 and Enhanced Host Controller Interface (EHCI)
v1.0 compatible
Additional key features include support for six USB ports, Fast
Ethernet MAC controller, AC97 interface, IEEE 1394 host con-
troller
(except for SiS963L Southbridge chipset)
, advanced power
management, integrated DMA controller and keyboard control-
ler.
Memory
•
Supports DDR up to 200/266/333 MHz SDRAM memory
module
•
Accommodates three unbuffered 2.5V 184-pin slots
•
Each slot supports up to 1 GB with a total maximum
capacity of 3 GB
AGP
The L7S7A includes an AGP slot that provides eight times the
bandwidth of the original AGP specification. The AGP 3.0
(8xAGP) offers a significant increase in performance along
with feature enhancements to AGP2.0. This interface repre-
sents the natural evolution from the existing AGP to meet the
ever-increasing demands placed on the graphic interfaces
within the workstation and desktop environments.
AC’ 97 Audio
Codec
The AC’ 97 Audio codec is compliant with the AC’ 97 2.2
specification, and supports 18-bit ADC (Analog Digital Con-
verter) and DAC (Digital Analog Converter) resolution as well
as 18-bit stereo full-duplex codec with independent and vari-
able sampling rates. Further features include support for four
analog line-level stereo inputs.
Expansion
Options
The mainboard comes with the following expansion options:
•
Five 32-bit PCI slots
•
One 4x/8x AGP slot (supports 1.5V AGP Interface only)
•
A Communications Network Riser (CNR) slot (AC97 inter-
face only)
