Intuitive Technologies Powering the Pentium® 4 Platform

Optimized for the Intel® Pentium® 4 processor, the VIA PT880 chipset features support for 800MHz FSB, Hyper-Threading, AGP 8X and includes the new VIA DualStream64™ dual channel DDR400 memory controller. Paired with the acclaimed VIA VT8237R Plus South Bridge, the PT880 provides professionals and PC enthusiasts with unparalleled performance in demanding 3D graphics and multimedia applications, as well as a full arsenal of multimedia and I/O connectivity options including native Serial ATA/RAID, 8 Channel Audio, and Gigabit Ethernet.

Harnessing revolutionary new intuitive technologies, the VIA DualStream64™ memory controller enables lightning fast access to system memory and optimum system performance through an enhanced data prefetch protocol and improved memory branch predictions. Further performance enhancements include a larger on-chip branch table and a tighter read/write turn-around for improved clock timings. Furthermore, with an asynchronous bus design, the PT880 allows maximum system flexibility and optimization options, as is often demanded by today's power users.

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 VT8237R Plus also features the VIA Vinyl Multichannel Audio Suite for superlative 6-channel and 8-channel immersion audio. VIA's Advanced Connectivity Suite 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 PT880 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 Ultra V-Link interconnect running at speeds of up to 1066MB/s between the North and South Bridge.

Benefits of VIA PT880

DualStream64
VIA DualStream64 is the world's most intelligent dual channel memory controller featuring revolutionary new intuitive technologies. The VIA DualStream64™ memory controller enables lightning fast access to system memory and optimum system performance through an enhanced data prefetch protocol and improved memory branch predictions. Further performance enhancements include a larger on-chip branch table and a tighter read/write turn-around for improved clock timings.

Native Serial ATA/RAID Support
The VIA DriveStation™ Advanced Connectivity 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, and RAID 0+1*, ensuring optimum data integrity and system performance. User friendly software interface enables easy disk array configuration.

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.
