Compatible with the latest Intel® processors, the VIA PT880 Ultra chipset includes support for 1066MHz FSB and Hyper-Threading Technology.

logo_dualgfxFeaturing VIA’s revolutionary Universal Graphics Interface (UGI), the VIA PT880 Ultra enables support for the latest generation of PCI Express Graphic cards as well as existing AGP 3.0 graphics cards, providing OEMs, SIs, and end-users much needed flexibility during the transition period. Furthermore, motherboards based on the VIAPT880 Ultra support VIA DualGFX Express, by running both AGP and PCI-Express graphics cards simultaneously, providing the ability to connect to as many as four separate displays.


By harnessing the advanced VIA StepUp memory controller technology, motherboards based on the VIA PT880 Ultra can support either DDR or DDR2 memory modules on the same motherboard, providing users the flexibility to use whatever memory standard best suits their requirements.

pt880ultra_mainThe VIA PT880 Ultra features a high bandwidth Ultra V-Link bus to allow communication between the chipset’s North and South bridges at a blazing 1GB/s. When combined with solutions such as the market-leading VIA VT8237R Plus South Bridge and a broad array of VIA companion chips, the VIA PT880 Ultra 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.

The VIA PT880 Ultra chipset has received PCI-Express certification, having successfully completed the rigorous testing procedures of the PCI-SIG Compliance Workshop.

Benefits of VIA PT880 Ultra

VIA Universal Graphics Interface: The unique VIA Universal Graphics Interface allows connection of both AGP and PCI Express graphics cards on the same motherboard, truly bridging the gap between the two standards. Furthermore, users can enable advanced VIA DualGFX Express technology by running AGP and PCI Express graphics cards simultaneously, opening up a new expanse of user options.

VIA DualGFX Express: For users requiring powerful multitasking capabilities, VIA’s unique DualGFX Express technology allows two PCI Express graphics cards to be implemented on a single motherboard, supporting any brand of graphics card. With the ability to run two high-performance graphics cards simultaneously, user can easily connect to two, three, or even four monitors with no substantial hit on performance.

VIA StepUp Memory Support: The VIA PT880 Ultra 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 VT8237R Plus 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 and VIA Vinyl Gold Audio enable crisp, clear performance, representing the highest levels of audio quality in a mainstream integrated or onboard solution.

Ultra V-Link Bus :Delivering data throughput speeds of up to 1066 MB/s from the VIA VT8237R Plus South Bridge to the VIA PT880 Ultra North Bridge, the Ultra V-Link interface delivers the necessary bandwidth and low latency required by today’s increasingly demanding multimedia applications.

VIA Modular Architecture Platform :The VIA PT880 Ultra 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 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.
