Intel® EM64T The motherboard supports Intel® Pentium® 4 CPUs with the Intel® EM64T (Extended Memory 64 Technology). The Intel® EM64T feature allows your computer to run on 64-bit operating systems and access larger amounts of system memory for faster and more efficient computing. See the Appendix for details. 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. DDR2 memory support The motherboard supports DDR2 memory which features data transfer rates of 667/533 MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia, and Internet applications. The dual-channel DDR2 architecture doubles the bandwidth of your system memory to boost system performance, eliminating bottlenecks with peak bandwidths of up to 10.7 GB/s. See pages 1-15 to 1-17 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. Serial ATA Technology The motherboard supports the Serial ATA technology through the Serial ATA interfaces and the SIS 965L. The SATA specification allows for thinner, more flexible cables with lower pin count, reduced voltage requirement, and up to 150 MB/s data transfer rate. See page 1-27 for details. SIS Advanced HyperStreaming™ Architecture The motherboard supports the SIS HyperStreaming™ technology that smartly manages data streaming between the Northbridge and Southbridge, memory, graphics interface, and other peripherals for efficient and superior performance.
