Bringing Exceptional Integrated Graphics and Innovative Features to the AMD64 Platform

This product is available fully ROHS-compliant.

The VIA K8M800 is the world's first chipset for the AMD64 platform to feature an Integrated Graphics Processor (IGP) as well as an unparalleled range of cutting edge I/O and multimedia features, allowing both consumer and business users to enjoy an exceptional graphics experience while unleashing the full performance potential of the AMD Athlon64™ and Opteron™ processors.

At the heart of the K8M800 North Bridge lies the all new VIA Chrome® Pro IGP, delivering a rich visual experience through the implementation of innovative features such as integrated MPEG-2 hardware acceleration for flawless digital media playback and a dual pixel pipeline, 128 bit 2D/3D engine with support for up to 64MB of shared 64/128bit DDR memory for robust 3D gaming and applications. The K8M800's highly flexible and scalable architecture also allows for an external AGP 8X port for optional graphic card upgrades.

VIA's ground breaking Hyper8™ technology provides a fast 16-bit/1.6GHz HyperTransport link between the K8M800 North Bridge and next generation 64-bit compatible platforms based around AMD Athlon™ 64 and Opteron processors, achieving data transfers speeds of up to 6.4GB/s. Combined with the VIA VT8237R Plus South Bridge and VIA companion chips, the K8M800 enables an unparalleled range of cutting edge I/O and multimedia features, including Native Serial ATA/RAID, 7.1-surround audio, and Gigabit Ethernet.

Featuring the VIA DriveStation™ Controller Suite, the VIA VT8237R Plus South Bridge provides the most comprehensive support high-performance integrated storage interface technologies available on the market today. In addition to enabling high-speed 150MB/s dual channel connections to Serial ATA Hard Drives while retaining support for up to four Parallel ATA-133 devices, it combines exceptionally fast disk data transfer rates and optimal data integrity with easy installation and manageability through V-RAID, the first native RAID controller integrated into a South Bridge supporting multiple RAID Level 0, RAID Level 1, RAID 0+1, and JBOD configurations.

The VIA VT8237R Plus also features the VIA Vinyl™ Multichannel Audio Suite for superlative integrated and onboard 5.1 and 7.1 surround sound, and offers a host of high-bandwidth connectivity options, including support for the VIA Gigabit Ethernet companion chip, integrated 10/100Mbps Fast Ethernet and up to eight high-speed USB 2.0 ports.

The VIA K8M800 benefits from VIA's unique V-MAP (VIA Modular Architecture Platform) architecture that facilitates faster product development and speeds up time to market, and features the high-throughput V-Link interconnect running at speeds of up to 533 MB/s between the North and South Bridge.

Native Serial ATA/RAID Support
The VIA DriveStation™ Controller Suite with native dual channel Serial ATA/RAID controller, provides direct support for two 150MB/s Serial ATA devices and its unique SATAlite™ interface expands support for two additional SATA devices. The V-RAID controller features native RAID 0, RAID 1, RAID 0+1* and JBOD, ensuring optimum data integrity and system performance. The user friendly V-RAID software interface enables easy disk array configuration and management.

VIA Vinyl Multichannel Audio Suite
Delivering rich, warm surround sound at resolutions as high as 24/96 through up to six- or eight-channel outputs, the VIA Vinyl Audio 5.1 surround sound and VIA Vinyl Gold Audio 7.1 surround sound enables crisp, clear performance, representing the highest levels of audio quality in a mainstream integrated or onboard solution.

Unified VIA Hyperion 4in1 Drivers
VIA's unified approach to drivers has been established for eight generations of chipsets, allowing end users to benefit from seamless hardware and software compatibility.

* 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.
