Intel® E7520 and E7320 Chipsets
Click to Enlarge
The Intel® E7520 and E7320 chipsets, the next generation Intel® dual-processor (DP) server chipset technology, enable reduced power consumption and improved platform reliability and system manageability. These chipsets enable new dual-processor servers to deliver outstanding performance, dependability and value to enterprise front-end, small-medium business (SMB), or high performance computing (HPC) applications.

Performance-Enhancing Features
Dual Intel® Xeon® processors and an 800 MHz system bus provide up to 6.4 GB/s of available bandwidth delivering a high-performance balanced platform with greater bandwidth for increased memory and I/O throughput compared to previous generation platforms.
Dual DDR2-400 memory channels deliver 6.4 GB/second bandwidth and up to 16 GB of physical memory, providing up to 20 percent increase in memory bandwidth over DDR333 and up to a 40 percent decrease in power consumption.
PCI Express* I/O delivers up to 4 GB/s throughput on each x8 interface for demanding I/O and networking applications, allowing I/O to keep pace with the rest of the platform.

Intel® E7520 and E7320 Chipset Features
Features 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*1 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 Correction2 (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.
