Introducing the Motherboard
Feature
• Accommodates the latest Intel P4/Celeron processors
• Supports a system bus (FSB) of 800/533MHz
• Supports “Hyper-Threading” technology CPU
The RS400 Northbridge (NB) and SB400 Southbridge (SB) chipsets are based on an
innovative and scalable architecture with proven reliability and performance.
RS400 (NB)
• Supports 128-bit dual-channel DDR/DDR2 SDRAM interface
• 1 x2 (expandable to x4) A-Link Express interface (PCI Ex-
press 1.0a compliant) for connection to the ATI IXP
• Supports one PCI Express x16 for Graphics Interface, fully
compliant to the PCI Express Base Specification revision
1.0a.
• Supports up to four x1 PCI Express for general purpose
links
• Supports 64, 128, 256, 512 Mb, and 1Gb system memory,
with x8, x16, and x32 memory device width
“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.
The RS400-A uses an LGA775 type of Pentium 4 that carries the following features:
