Intel® E7501 Chipset |
|
|
|
|
 The second in a family of volume server chipsets, the Intel® E7501 chipset supports dual-processor (DP) server systems optimized for the Intel® Xeon® processor. The Intel E7501 chipset design delivers maximized system bus, memory and I/O bandwidth to enhance performance, scalability and end-user productivity while providing a smooth transition to next-generation server technologies.
|
| Platform Features that Maximize Performance |
 | Dual Intel® Xeon® processors with a 533 MHz system bus provide up to 4.3 GB/s of available bandwidth. |
| Dual DDR-266 memory channels operate in lock-step to provide up to 4.3 GB/s of memory bandwidth. |
| Three hub interface 2.0 connections provide multiple high-bandwidth I/O configuration options, yielding up to 3.2 GB/s of I/O bandwidth. |

| Features |
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. |
| 533 MHz system bus capability |
Supports a high-performance platform by enabling a 4.3 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 Intel® 82870P2 controller hub devices provides greater than 1 GB/s of bandwidth. Error Correction Code (ECC) protection, coupled with high data transfer rates, support I/O segments with greater reliability and faster access to high-speed networks. |
| Intel® 82870P2 controller hub |
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 Intel 82870P2 controller hub device allow up to 6 PCI-X buses per system. |
| Dual-channel DDR-266 memory interface |
Offers a maximum memory bandwidth of 4.3 GB/s through a 144-bit wide, 266 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 Correction1, hardware memory scrubbing, MCH SMBus target interface, hub interface ECC, and the availability of enhanced error status information maintained through reset. |

| † Hyper-Threading Technology (HT Technology) requires a computer system with an Intel® Processor supporting HT Technology and an HT Technology enabled chipset, BIOS, and operating system. Performance will vary depending on the specific hardware and software you use. See www.intel.com/products/ht/hyperthreading_more.htm for more information including details on which processors support HT Technology.
1In 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. |
