Introducing the Motherboard
Introduction
Thank you for choosing the RS400-A motherboard. This motherboard is a high perfor-
mance, enhanced function motherboard that supports LGA775 Pentium 4/Celeron proces-
sors for high-end business or personal desktop markets.
The motherboard incorporates the RS400 Northbridge (NB) and SB400 Southbridge (SB)
chipsets. The Northbridge supports a Front Side Bus (FSB) frequency of 800/533 MHz using
a scalable FSB Vcc_CPU. The memory controller supports DDR/DDR2 SDRAM interface
of DDR400/333/266 MHz or DDR2-667/533/400 MHz. It supports four DDR Sockets with
up to maximum memory size of 2GB. Aside from the onboard AGP Express slot, one PCI
Express x16 slot, intended for Graphics Interface, is fully compliant to the PCI Express
Base Specification revision 1.0a.
The SB400 Southbridge supports two PCI slots which are PCI 2.3 compliant. In addition,
two PCI Express x1 slots are supported, fully compliant to the PCI Express Base Specifica-
tion, Revision 1.0a. It implements an EHCI compliant interface that provides 480Mb/s
bandwidth for eight USB 2.0 ports. Two onboard IDE connectors supports 4 IDE devices in
UDMA 133/100/66/33 modes. The Southbridge integrates a Serial ATA host controller that
is SATA v1.0 compliant, supporting four SATA ports with maximum transfer rate up to 150
MB/s each.
The RS400-A motherboard is equipped with advanced full set of I/O ports in the rear panel,
including PS/2 mouse and keyboard connectors, COM1, LPT1, VGA, four USB ports, one
optional LAN port, and audio jacks for microphone, line-in and line-out.

Feature
Processor
The RS400-A uses an LGA775 type of Pentium 4 that carries the following features:
•
•
•
Accommodates the latest Intel P4/Celeron processors
Supports a system bus (FSB) of 800/533MHz

“Hyper-Threading” technology enables the operating system into thinking it’s hooked
up to two processors, allowing two threads to be run in parallel, both on separate
“logical” processors within the same physical processor.
Chipset
The RS400 Northbridge (NB) and SB400 Southbridge (SB) chipsets are based on an
innovative and scalable architecture with proven reliability and performance.
