Processor and Chipset Intel® Server Board Set SE8500HW4

2.2Intel® E8500 Chipset

The Intel® E8500 Chipset is the highest performance, most scalable platform offering in the 64- bit Intel® Xeon™ Processor MP family. The chipset represents the sixth-generation Intel four- way multi-processor platform, is architected for multi-core processors and includes these advanced features:

ƒSupport for up to four 64-bit Intel® Xeon™ Processors MP FSB operating at 667 MHz

ƒMaintains coherency across both buses

ƒDouble-pumped 40-bit address buses with a total address bandwidth of 167 million addresses/second

ƒQuad-pumped, 64-bit data bus providing a bandwidth of 5.3 GB/s per bus

ƒx8 Single Device Data Correction (x8 SDDC) technology for memory error correction

ƒHardware memory initialization

ƒECC protection on data signals and parity protection on address signals

ƒSupport for hot-plug memory and performance operations

This section provides an overview of the chipset components, for more detailed information refer to the Intel® E8500 Chipset Datasheets referenced in the Appendix.

2.2.1North Bridge (NB)

The Intel® E8500 Chipset North Bridge (NB) is the center of the system architecture and provides interconnection to:

ƒUp to four 64-bit Intel® Xeon™ Processors MP via two 667 MHz FSBs optimized for server applications

ƒUp to 64GB memory via four Independent Memory Interfaces (IMI)

ƒI/O subsystem components via one PCI Express and the Intel® 82801EB I/O Controller Hub 5 (ICH5)

2.2.2eXtended Memory Bridge (XMB)

The Intel® E8500 Chipset eXtended Memory Bridge (XMB) provides interface between the NB and DDR2 400MHz DIMMs. The Intel® Server Board Set SE8500HW4 includes up to four Memory Boards, each with an XMB and four DDR2 400MHz DIMM locations.
