Features and benefits

Supports two Intel® Xeon® processors over an 800 MHz system bus for dual-processing workstation and server systems

Optimized performance for multiple DP market segments and price points, supporting a larger number of users/transactions with faster response times.

800 MHz system bus capability

Increased platform bus bandwidth (50% more than 533 MHz) delivers increased system performance.

PCI Express*

Serial I/O technology that provides a direct connection between the MCH and PCI Express* devices with bandwidth up to 4 GB/s on each PCI Express* x8 interface; PCI Express offers higher bandwidth, lower latency and less I/O bottlenecks than PCI-X.

DDR2-400 memory interface

  • Offers a maximum memory bandwidth of 6.4 GB/s.
  • Decreased power consumption—especially important on dense rack, HPC and blade configurations.
  • Increased DIMMs per system providing enhanced memory scalability for memory-intensive applications.
Intel® 6700PXH 64-bit PCI hub
  • Optional component introduces next-generation PCI/PCI-X performance and significant enhancements to platform flexibility.
  • Supports two independent 64-bit, 133 MHz
    PCI-X segments and two hot-plug controllers (one per segment).

Intel® Hub Interface 1.5 connection to the Memory Controller Hub (MCH)

Point-to-point connection between the MCH and the Intel® 82801ER I/O controller hub or Intel® 6300ESB I/O controller hub provides 266 MB/s of bandwidth.

Advanced platform RAS

  • Features such as memory Error Correction Code (ECC), Intel® x4 Single Device Data Correction (x4 SDDC), DIMM sparring, DIMM scrubbingand memory mirroring can improve system reliability.
  • 32-bit CRC on PCI Express*.
  • SMBus port hooks into Intel® E7520 and Intel® E7320 chipsets for remote management operation and support for variety of third-party Base Management Controller (BMC) and BIOS solutions.
