This product is available fully ROHS-compliant.

Optimized to deliver a great Hi-Def™ visual experience when playing digital video content, the VIA P4M800 Pro chipset supports the latest platform technologies such as Dual Core processors, 1066MHz FSB, and DDR2.

By harnessing the advanced VIA StepUp memory controller technology, motherboards based on the VIA P4M800 Pro 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.

The VIA P4M800 Pro 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 VT8251 South Bridge and a broad array of VIA companion chips, the VIA P4M800 Pro 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.

Leveraging an advanced shared memory architecture, the VIA P4M800 Pro utilizes the VIA Chrome® Pro Integrated Graphics Processor (IGP) ensuring optimal performance for all multimedia, entertainment, and productivity applications. With an internal data flow equivalent to the latest AGP 8X graphics cards, a 200MHz 2D/3D graphics engine features dedicated 128-bit data paths for pixel data flow and texture/command access.

The VIA Chrome® Pro IGP graphics core also features the Chromotion CE Video Display Engine, raising the bar for digital entertainment support on PC systems. The P4M800 Pro is able to deliver the Hi-Def experience via a comprehensive range of display devices, supporting outputs to CRT, LCD, standard definition TV and HDTV up to 1080p resolution*.

The Chromotion CE Video Display Engine employs a multi-faceted approach to displaying multimedia content, implementing a number of advanced tools at every stage of video processing. These include integrated MPEG-2 decoding, for flawless digital video playback with ultra-low CPU-utilization, and advanced rendering tools such as Adaptive De-Interlacing and Video Deblocking, which ensure clearer playback of digital content on all display devices.
