Product highlights

Latest processor technology

The motherboard comes with dual 604-pin surface mount ZIF sockets
designed for the Intel

Xeon™ processor with 800 MHz Front Side Bus

(FSB) and 1 MB L2 cache. The processor incorporates the Intel

Hyper-Threading Technology, the Intel

NetBurst™ micro-architecture that

features hyper-pipelined 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

E7520 and Intel

ICH5R chipset

The Intel

E7520 Memory Controller Hub (MCH) and the Intel

ICH5R (I/O

controller hub) provide the vital interfaces for the motherboard.

The MCH provides the processor, dual-channel DDR 333 memory, and PCI
Express interfaces. The ICH is a new generation server class I/O controller
hub that provides the interface for PCI 2.3.

DDR333 memory support

The motherboard supports DDR333 memory which features data transfer
rates of 333 MHz to meet the higher bandwidth requirements of the latest
server applications. The dual-channel memory architecture doubles the
bandwidth of your system memory to boost system performance, eliminating
bottlenecks with peak bandwidths of up to 5.32 GB/s.

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 or PCI-X specifications. See page 2-20 for details.
