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.
