ASUS P5RD2-VM 1-3
ATI Radeon ® XPRESS 200/ULI M1575 chipset
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 Intel SpeedStep ® Technology (EIST)
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™ interface
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 audio
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.
Serial ATA 3Gb/s technology
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.
