1.2.1 Product highlights

Latest processor technology

The NR-LSR motherboard supports the Intel® Pentium® 4 processor via a 478-pin surface mount ZIF socket. The processor features the Intel® NetBurst™ micro-architecture that includes hyper-pipelined technology, a rapid execution engine, a 400MHz system bus, and an execution trace cache to offer a significant increase in performance. See page 2-4 for more information.

DDR memory support

Employing the Double Data Rate (DDR) memory technology, the NR-LSR motherboard supports up to 8GB of system memory using PC2100/1600 registered ECC DDR DIMMs. The ultra-fast 200MHz memory bus doubles the speed of the PC100 SDRAM to deliver the required bandwidth for the latest 3D graphics, multimedia, and Internet applications. See page 2-10.

Dual-channel Ultra-160/320 SCSI

The LSI® 53C1010R 64-bit/66MHz PCI SCSI controller is onboard to support dual-channel Ultra-160 SCSI connectors that provide high-speed data transfer interfaces.

Advanced 64-bit PCI-X slots

The 64-bit/133MHz expansion slot onboard supports a proprietary riser card with two PCI-X slots (on both sides). The PCI-X slots maximize I/O bandwidth for the next generation 64-bit PCI-X cards that support 133/100MHz bus. The PCI-X specification 1.0a allows full peer-to-peer transactions between PCI buses and provides options for intelligent I/O and server management cards.

Onboard LAN

The motherboard comes with the Intel® 82550PM Fast Ethernet controller and the Intel® 82544GC Gigabit Ethernet controller to support the latest LAN technologies.
