2-1. Features of SG-71 Motherboard
The SG-71 is designed for use with Intel’s latest generation of Pentium
®
4 (400/533 MHz FSB) 478 pins
processors. Based on the new SiS 651 chipsets (SiS 651 & SiS 962L), The SiS 651 Host, Memory and
AGP Controller integrates a high performance host interface for Intel
®
Pentium
®
4 processor, a high
performance memory controller, a AGP interface, and SiS MuTIOL 1G Technology connecting w/ SiS
962L MuTIOL 1G Media IO.
The SG-71 can support external AGP slot with AGP 1X/2X/4X capability and Fast Write Transactions.
The memory controller supports two DDR DIMMs (Unbuffered & Non-ECC) for a maximum of up to 2
GB. It can offer bandwidth up to 2.7 GB/s under DDR333 in order to sustain the bandwidth demand from
host processor, as well as the multi I/O masters and AGP masters.
The SG-71 has integrateds Universal Serial Bus 2.0 Host Controllers, the Audio controller, the ATA-133
IDE controllers, the high-speed host controller implements an EHCI interface that provides 480 Mb/s
bandwidth for six USB 2.0 ports. Each of six USB ports can be automatically routed to support a
High-speed USB 2.0 devices or Low-speed USB 1.1 devices. The SG-71 has integrated ATA-133 IDE
Master/Slave controller features Dual Independent IDE channels supporting PIO mode 0,1,2,3,4, and
Ultra DMA 33/66/100/133 MB/s. It provides two separate data paths for the dual IDE channels that
sustain the high data transfer rate in the multitasking environment.
SG-71 offers users a robust, high performance and low cost computing-platform. Moreover, on board
10/100 Mb LAN provides high speed networking capability, and built-in 2-channel audio delivers a
multimedia solution.
This motherboard also supports three PCI slots and one AGP slot. In addition, this motherboard gives
users enormous flexibility through ABIT’s SoftMenu
™
with plenty clock frequency selections. The user is
able to alter both the FSB speed and the multiplier to get the CPU processing speed of your choice. This
motherboard has built-in hardware monitoring functions that monitors and protects your computer,
ensuring a safe computing environment.
