In accordance with AMD?s launch of the 400MHz front side bus Athlon? XP3200+ desktop CPU, SiS announced the SiS748 core logic chipset today. As the highest level core logic chipset for AMD platforms, SiS748 has been well received right at its launch to the market. Currently, SiS748 has become the first choice of many motherboard makers, including leading makers like AOpen Inc, ASRock Inc, FIC (First International Computer Inc.) and MSI (Micro Star International Inc). The excellent performance of SiS748 has made a great compliment to AMD high level platforms. New motherboards using SiS748 include AK76F-400N from AOpen, K7S8XE from ASRock, KT748 from FIC, and 748Delta from MSI. Each motherboard maker has adapted exclusive technologies respectively to extend the horizon of SiS748 so as to meet different customer requirements. The SiS748 logic chipset supports the AMD Athlon XP processor 3200+ with 400 front side bus, integrated high-performance DDR400 memory controller, AGP8X interface, MuTIOL® 1G and HyperStreaming? functions. It is a unique logic chipset equipped with all these 5 top-lined features. The exclusive function of MuTIOL® 1G technology will be best demonstrated when combining SiS748 to SiS963L south bridge chip. This combination provides faster and smoother communication links between north and south bridge chips at 1GB/sec when running at 533MHz on 16-bit two-way data bus. SiS963L is also integrated with USB 2.0/1.1 controller, ATA133/100/66 standard dual IDE channels, 5.1 channel audio, V.90 modem and Ethernet function to provide perfect high-speed transfer interface for users.   Features Benefits CPU supported AMD Athlon XP FSB 400 MHz.
