1.3.1Product highlights

Latest processor technology

The motherboard comes with two LGA-771 sockets that support DualCore and Quad-Core Intel® Xeon™ processors with 1600/1333/1066 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

®Extended Memory 64-bit Technology, enabling the support for 64-bit operation system, such as 64-bit Windows® and Linux. See page 2-9 for details.

Intel® Seaburg and Intel® ESB2E chipset

The Intel® Seaburg Memory Controller Hub (MCH) and the Intel® ESB2E provide the vital interfaces for the motherboard. The MCH provides two channels for processor, quad-channel FB-DIMM memory support, and two PCI Express 2.0 interfaces. The Intel® ESB2E 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 214 for details.

PCIe 2.0

This motherboard supports the latest PCIe 2.0 device for twice the current speed and bandwidth. This enhances system performance while still providing backward compatibility to PCIe 1.0 devices. See page 2-21 for details.
