1.4Special features
1.4.1Product highlights
Latest processor technology 
The motherboard comes with two LGA-771 sockets that support Dual‑Core and Quad-Core Intel® Xeon™ processors with 1333/1066/667 MHz Front Side Bus (FSB). Dual-core processors contain two physical CPU cores to meet demands for more powerful processing. Intel® Xeon™ processors incorporate the Intel® Hyper‑Threading Technology and Extended Memory 64-bit Technology (EM64T). The EM64T enables the support for 64-bit operation system, such as 64-bit Windows® and Linux. See page 2-11 for details.
Intel® 5000V and Intel® 6321ESB chipset
The Intel® 5000V Memory Controller Hub (MCH) and the Intel® 6321ESB provide the vital interfaces for the motherboard.
The MCH provides the processor, dual-channel FB-DIMM memory support, and PCI Express interfaces. The Intel® 6321ESB is a new generation server class I/O controller hub that provides the interface for PCI 2.3, PCI Express, and PCIX.
Intel® EM64T 
The motherboard supports Intel® processors 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.
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.
FB-DIMM memory support
This motherboard supports fully buffered DIMMs (FB-DIMMs), the latest memory solution that extends memory capacity and provide high-speed, high-density system memory peformance. FB-DIMMs use Advanced Memory Buffer (AMB) chips that transmit signals between the memory modules and controllers with improved signal integrity and reduced errors. See page 2‑16 for details.
