Intel® 975X Express/ICH7R chipset The Intel® 975X Express Memory Controller Hub (MCH) and the ICH7R I/O controller hub provide the vital interfaces for the motherboard. The Intel® 975X Express is the latest chipset designed to support Dual PCI Express graphics, along with the maximum 8 GB dual-channel DDR2 800/667/533 MHz, 1066/800/533 FSB, and dual-core CPU. The MCH also supports the Intel® Memory Pipeline Technology (MPT) that boosts system performance. The Intel® ICH7R Southbridge integrates four Serial ATA I/II connectors enabled through the Serial ATA 3 Gb/s RAID controller to ensure data security and enable powerful multi-task processing. 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. Intel® Memory Pipeline Technology (MPT) The Intel® MPT increases system-level and standard operating performance by optimizing memory access between CPU and system memory. 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 4-27 and the Appendix for details. DDR2 memory support The motherboard supports DDR2 memory, which features data transfer rates of 800/667/533 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 page 2-14 for details.
