Desktop Chipsets

* RAID Level 0+1 requires four Serial ATA drives; support for the two additional drives can only be implemented with two external Serial ATA ports enabled through a SATALite PHY.

Unified VIA Hyperion 4in1 Drivers
VIA's unified approach to Chipset drivers has been established for 8 generations of Chipsets, allowing end users to benefit from high performance and seamless compatibility when using any Microsoft Windows?.

Native Serial ATA Support
The VT8237R Plus is the latest in a series of market leading South Bridge chips integrating the latest in I/O innovation like Serial ATA enabling supreme performance in the most Hard Drive intensive tasks.

A Platform for Next Generation Integrated Audio
The 6-Channel Surround Sound Audio supported in the VT8235 and VT8237R Plus South Bridges, combined with a high quality external Codec like the VIA VT1616 with enhanced driver support, enables a rich, vibrant sound that will enhance the user experience when listening to music, watching movies, or playing games.

FastStream64 Technology
VIA FastStream64 Technology uses an expanded array of prefetch buffers to reduce latency in the memory controller, extending performance at a lower transistor cost than dual channel implementations. With a 200/266/333MHz processor bus and supporting DDR200/266/333/400 memory, the VIA KT400A provides lightning fast access to system memory and can reach a peak bandwidth of 3.2GB/sec, 25% greater than the KT400, enabling the full performance potential of the fastest AMD Athlon XP processors to be harnessed.

The VT8237R Plus also features support for Parallel ATA-133 devices extending flexibility to the system integrator by allowing for mainstream or value configurations leveraging the existing technology standard. Additional features include a VIA MAC for 10/100Mbps Fast Ethernet, integrated PCI support, and an MC'97 modem. The VIA KT400A also benefits from VIA Hyperion 4in1 Drivers which deliver seamless compatibility with the latest software and hardware.

In addition, the VIA KT400A supports the very latest I/O technologies including AGP 8X deriving maximum performance from the most powerful graphics processors. 6-Channel surround sound AC'97 audio completes the audio-visual experience offering an integrated high quality sound solution when listening to mp3s, watching movies, or playing the latest games. The KT400A North Bridge is connected to a through the fast 8X V-link connection at 533MB/s. With two channel native support for Serial ATA in the South Bridge supplying 150MB/s of bandwidth, as well as up to Eight USB 2.0 ports the VT8237R Plus offers the highest possible peripheral performance for professional and home users.

Building on the success of seven generations of market leading Chipsets for the AMD Athlon XP processor, the VIA KT400A boasts a complete set of today's cutting-edge features combined with VIA's ultra efficient FastStream64 memory controller technology, delivering performance equivalent to or superior than 128-bit solutions. DDR400 memory support, offering 20% more memory bandwidth to the CPU than DDR333, and the fast 200/266/333MHz processor bus, unleash the full power of AMD Athlon XP processors, enabling stunning performance across the full spectrum of applications.

The VIA KT400A takes the AMD Athlon XP processor to the summit of system performance with a FastStream64 memory controller technology, 333MHz Front Side Bus, AGP 8X Graphics, 6-Channel Audio, Serial ATA, ATA-133, USB 2.0 and 8X V-Link chip interconnect.
