1.3.1 Product highlights

Latest processor technology

The PR-DLS533 motherboard supports the Intel® Xeon processor via dual 603/604-pin surface mount ZIF sockets. The processor features the Intel® NetBurst™ micro-architecture that includes hyper-pipelined technology, a rapid execution engine, a 533/400MHz 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-DLS533 motherboard supports up to 12GB of system memory using PC2100/1600 registered ECC DDR DIMMs. The ultra-fast 266MHz memory bus doubles the speed of the PC133 SDRAM to deliver the required bandwidth for the latest 3D graphics, multimedia, and Internet applications. See page 2-10.

Dual-channel Ultra320 SCSI

The LSI® 53C1030 64-bit/100MHz PCI-X SCSI controller is onboard to support dual-channel Ultra320 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.

ATA/100 IDE support

The dual-channel bus master IDE connectors comply with the ATA/100 protocol and supports ATA/100, Multi-Word DMA Mode2, PIO modes 3 & 4 IDE devices such as ATAPI IDE CD-ROM, CD-R/RW, ZIP, and LS-120 drives.
