Processor The K7S5A+ mainboard uses an AMD 462-pin Socket A that
has the following features:
• Supports 200/266 MHz frontside bus (FSB)
• Accommodates AMD AthlonXP/Athlon/Duron processors
Chipset The SiS745 chipset is based on an innovative and scalable
architecture with proven reliability and performance. A few of
the chipset’s advanced features are:
• A low 2.5-volt DDR266 SDRAM power consumption
which makes it an excellent solution for notebooks and
desktops with a small footprint
• 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 connec-
tion 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 perform-
ance, 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 can accommodate 2.5V DDR SDRAM. It ac-
commodates three unbuffered 2.5V 184 pin slots. Each slot
can support up to 512 MB with a total maximum capacity of 1.0
GB (2 unbuffered DDR333 DIMM) or 1.5GB (3 unbuffered
DDR266/DDR200 DIMM).
VGA The K7S5A+ includes a 4xAGP slot that provides four times
the bandwidth of the original AGP specification. AGP technol-
ogy 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.
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.
Onboard LAN
(optional) The Realtek RTL8100B LAN chip is incorporated in the chipset
providing the mainboard with integrated Ethernet PCI LAN
capabilities.
Expansion
Options K7S5A+ has five 32-bit PCI slots, an AGP slot and CNR
(Communications and Networking Riser) slot.
The K7S5A+ supports Ultra DMA bus mastering with transfer
rates of 33/66/100 MB/sec.
