Features and benefits
Supports 2 Intel® Xeon® processors with 512 KB L2 cache for dual-processing server systems Delivers a platform that brings Intel NetBurst® microarchitecture and the Hyper-Threading Technology of the Intel® Xeon® processor to deliver best-in-class performance for peak server workloads.
400 MHz system bus capability Supports a high-performance, balanced platform by enabling a 3.2 GB/s system bus bandwidth that can support greater memory and I/O bandwidths.
Intel® Hub Architecture 2.0 connection to the MCH This point-to-point connection between the MCH and the 3 P64H2 devices provides greater than 1 GB/s of bandwidth. Error Code Correction (ECC) protection, coupled with high data transfer rates, support I/O segments with greater reliability and faster access to high-speed networks.
64-bit PCI/PCI-X Controller Hub-2 Introduces next-generation PCI/PCI-X performance and significantly enhances platform flexibility. Two independent 64-bit, 133 MHz PCI-X segments and 2 hot-plug controllers (1 per segment) for each P64H2 allow up to 6 PCI-X buses per system.
Dual-channel DDR-200 memory interface Offers a maximum memory bandwidth of 3.2 GB/s through a 144-bit wide, 200 MHz Double Data Rate (DDR) SDRAM memory interface with densities up to 512 megabits.
Advanced platform RASUM Provides a more reliable platform with features such as memory Error Correction Code (ECC) with Intel® x4 Single Device Data Correction (SDDC), hardware memory scrubbing, MCH SMBus target interface, hub interface ECC, and the availability of enhanced error status information maintained through reset.

1. Requires an Intel® Hyper-Threading Technology (Intel® HT Technology)-enabled system, check with your PC manufacturer. Performance will vary depending on the specific hardware and software used. Not available on the Intel® Core™ i5-750. For more information, including details on which processors support HT technology, visit www.intel.com/content/www/us/en/architecture-and-technology/hyper-threading/hyper-threading-technology.html.


2. In a x4 DDR memory device, the Intel® x4 Single Device Data Correction (Intel® x4 SDDC), provides error detection and correction for 1, 2, 3, or 4 data bits within that single device and provides error detection, up to 8 data bits, within two devices.
