1.3.1 Product highlights

Latest processor technology

The PR-DLSW motherboard supports the Intel® Xeon processor via dual 604-pin surface mount ZIF sockets. 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 PR- DLSW motherboard supports up to 12GB 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 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 PCI-X slots onboard maximizes I/O bandwidth for the next generation 64-bit PCI-X cards that support 133MHz 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.

AGP Pro 4X slot

The motherboard comes with an Accelerated Graphics Port (AGP) Pro 4X slot for 3.3V/1.5V AGP cards. The slot supports 1X, 2X, or 4X mode bus to support high performance 3D graphics applications.
