VIA PT890: Offering Full-Featured Support of Microsoft® Windows Vista™ Premium

This product is available fully ROHS-compliant.

Supporting a full range of Intel® processors up to 1066MHz FSB, the VIA PT890 provides SIs and OEMs an ideal solution to create a wide range of desktop systems that can take full advantage of the enhanced 3D capabilities of Microsoft's® Windows Vista™ Premium.

Optimized to work seamlessly with the latest PCI Express graphics cards, the VIA PT890 includes support for x16 PCI Express connectivity, delivering up to 4GB/s of dedicated graphics bandwidth per direction. The VIA PT890 also features additional x1 PCI Express peripheral support, providing 250MB/s per direction bandwidth to PCI Express peripheral devices such as Gigabit Ethernet and HDTV tuner cards.


The VIA PT890 also features VIA’s unique StepUp™ memory technology to provide support for both DDR and DDR2 memory standards on the same motherboard, allowing motherboard makers the option of implementing either standard depending on the demands of their target market at any given time.

The VIA PT890 features a high bandwidth V-Link bus to allow communication between the chipset’s North and South bridges at 533MB/sec. When combined with solutions such as the market-leading VIA VT8237A South Bridge and a broad array of VIA companion chips, the VIA PT890 provides a comprehensive range of storage, multimedia and connectivity features, including native Serial ATA and V-RAID, 6-channel or 8-channel VIA Vinyl Audio, VIA Velocity™ Gigabit Ethernet, USB2.0, and 1394.

    Benefits of VIA PT890

    VIA StepUp Memory Support
    The VIA PT890 integrates VIA’s StepUp memory technology for lightning fast access to system memory and optimum system performance. VIA’s StepUp memory technology enables support for DDR1 and DDR2 memory standards giving maximum flexibility.

    Native Serial ATA/RAID Support
    The VIA VT8237A South Bridge features a native Serial ATA/RAID controller, providing direct support for two 150MB/s Serial ATA devices, and an additional two (for a total of four SATA devices) in combination with the SATAlite™ interface. The integrated V-RAID controller supports native RAID 0, RAID 1, RAID 0+1* and JBOD, ensuring optimum data integrity and system performance, while 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 suite includes support for VIA Vinyl HD audio, VIA Vinyl AC'97 audio, and VIA Vinyl Gold Audio, representing the highest levels of audio quality in a mainstream integrated or onboard solution.

    VIA Modular Architecture Platform
    The VIA PT890 chipset is part of VIA's unique Modular Architecture Platform (V-MAP), which minimizes design times and time-to-market for motherboard partners through a flexible, pin-compatible design approach for VIA core-logic solutions. Motherboard partners are able to cover multiple market segments with fewer design resources, and also benefit from a single unified driver base.

    Unified VIA Hyperion Pro 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.
