Introducing the Motherboard
Feature
• Accommodates Intel P4 processors
• Supports a system bus (FSB) up to 800/533/400 MHz
• Supports “Hyper-Threading” technology CPU
The SiS661GX Northbridge (NB) and SiS964 Southbridge (SB) chipset is based on an
innovative and scalable architecture with proven reliability and performance.
SiS661GX
(NB)
• Supports 12 outstanding transactions and out-of-order
completion
• Accommodates high throughput SiS MuTIOL 1G intercon-
necting to SiS964 MuTIOL 1G media I/O with bi-directional
16-bit data bus to perform 1GB/s bandwidth in 133 MHz x
4 mode
• Supports AGP 8X/4X Interface with Fast Write Transaction
• Supports DDR400/333/266 SDRAM
“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 661GX/800-M uses a 478-pin socket type of Pentium 4 that carries the following
features:
SiS964
(SB)
• Supports DDR400/333/266 MHz DDR SDRAM memory module
• Accommodates two unbuffered DIMM of 2.5 volt DDR SDRAM
• Up to 1 GB per DIMM with maximum memory size up to 2 GB
