ATI Radeon® XPRESS 200/ULI M1575 chi pset

The ATI Radeon® XPRESS 200 Northbridge and the ULI M1575 Southbridge provide the vital interfaces for the motherboard. The ATI Radeon® XPRESS 200 Northbridge integrates the ATI X300 GPU, an integrated graphics processing unit (GPU) for enhanced 3D, 2D, and video capabilities. The Northbridge also provides the interface for a processor in the 775-land package with 533/800/1066 MHz front side bus (FSB), single channel DDR 2 memory, one PCI Express x1 slots, and a PCI Express x16 slot for discrete graphics card.

The ULI M1575 Southbridge represents the sixth generation I/O controller hub that provides the interface for PCI Express and 6-channel high definition audio.

Enhanced I ntel SpeedStep® Technol ogy (EI ST)

The Enhanced Intel SpeedStep® Technology (EIST) intelligently manages the CPU resources by automatically adjusting the CPU voltage and core frequency depending on the CPU loading and system speed or power requirement. See page 2-22 and the Appendix for details.

PCI Express™ i nterface

The motherboard fully supports PCI Express, the latest I/O interconnect technology that speeds up the PCI bus. PCI Express features point-to-point serial interconnections between devices and allows higher clockspeeds by carrying data in packets. This high speed interface is software compatible with existing PCI specifications. See page 1-21 for details.

6-channel audi o

The motherboard comes with the ADI AD1986A audio CODEC that provides 6-channel audio, audio jack-sensing and enumeration technology, and S/PDIF out support. See page 1-25 and 1-26 for details.

Seri al ATA 3Gb/s technol ogy

The motherboard supports the next-generation Serial ATA 3Gb/s technology through the Serial ATA interfaces and the ULI M1575 chipset. The SATA 3Gb/s specification provides twice the bandwidth of the current Serial ATA products. Additionally, Serial ATA allows thinner, more flexible cables with lower pin count, and reduced voltage requirement. See pages 1-28.
