1.3Special features
1.3.1Product 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 2-9 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 DDR2-400 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.
DDR2 memory support 
The motherboard supports DDR2 memory which features data transfer rates of 400 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 6.4 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.
Ultra320 SCSI feature (NCL-DS model only)
The Adaptec® AIC-7902 PCI-X SCSI controller is onboard to support two 68-pin Ultra320 SCSI connectors, each can connect up to 15 devices. See page 2-29 for details.
Zero-Channel RAID (ZCR) solution (NCL-DS model only)
The motherboard comes with a ZCR socket for an optional Zero-Channel RAID card, allowing RAID0 (striping), RAID1 (mirroring), RAID10, and RAID5 configurations. The ZCR capability provides a cost-effective high- performance and added reliability. See page 2-20 for details.
