Albatron K8X800 Pro II Motherboard



The K8T800 is Via’s newest edition to their long line of AMD chipsets. Albatron has taken this chipset and used it in their new K8X800 Pro II motherboard. This motherboard packs a lot of features into a motherboard waiting to unleash the power of AMDs 64-bit CPU. I want to get right into this review so lets take a look at the chipset. The information below is from Via’s website.

The VIA K8T800 chipset with Hyper8 technology is powering next generation 64-bit compatible platforms based around AMD Opteron™ and new Athlon™ 64 processors, including Dual Opteron™ processor based workstations and servers, and Athlon™64 processor based performance PC platforms. Combined with the VIA VT8237 South Bridge and VIA companion chips, the K8T800 enables an unparalleled range of cutting edge I/O and multimedia features, including an 1.6GHz HyperTransport Bus Link, AGP 8X, Native Serial ATA/RAID, 7.1-surround audio, and Gigabit Ethernet.

The HyperTransport link between the AMD64 processor and chipset provides a 16-bit/1.6GHz data transfer rate for a total bandwidth of 6.4GB/s. To counter the massive data loads and high propensity for signal interference of a 16-bit/1.6GHz link, several AMD64 supporting motherboards currently available feature a below-spec HyperTransport implementation. By reducing the processor-to-chipset HyperTransport link to deal with signal interference, total bandwidth is reduced from 6.4GB/s to as little as 3.2GB/s. With support for VIA’s unique Hyper8™ technology the VIA K8T800 enables the industry’s first full 16-bit/1.6GHz implementation of the HyperTransport bus for the AMD64 platform, ensuring AMD Opteron and AMD Athlon 64 processor based systems achieve their full performance potential.

Featuring the VIA DriveStation™ Controller Suite, the VIA VT8237 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 VT8237 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 K8T800 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.
