Product Brief
Intel^® E7520 Chipset
For Intel^® Xeon^TM Processor and Low Voltage
Intel^® Xeon^TM Processor with 800 MHz System Bus
Product Overview
The Intel^® E7520 chipset, utilizing next-generation
dual-processor high-bandwidth chipset
technology, enables reduced power consumption
with improved platform reliability and system
manageability compared to previous-generation
solutions. It enables new dual-processor
platforms to deliver outstanding performance,
dependability and value to embedded customers
and their applications.
The Intel E7520 chipset includes revolutionary
PCI Express*¹ serial I/O technology and next-
generation DDR2 memory technology to help
increase I/O bandwidth and reduce system latency
for data-intensive applications. The 800 MHz
system bus allows it to support the Intel^® Xeon^™
processor and Low Voltage Intel^® Xeon^™ processor
with 800 MHz system bus. These processors
support Intel^® Extended Memory 64 Technology^∆
(Intel^® EM64T), Hyper-Threading Technology,^§
Enhanced Intel SpeedStep^® technology and
Streaming SIMD Extensions 3 (SSE3) Instructions.
Advanced Technology Enhances
Price/Performance and Flexibility
The Intel E7520 chipset delivers a high-
performance, balanced platform with greater
bandwidth for increased memory and I/O
throughput. Designed specifically for performance
and volume applications, the chipset supports
a variety of configuration options, allowing
platforms to address a wide range of price points
and unique application environments. The E7520
Memory Controller Hub (MCH) is the central hub
for all data passing among the core system
elements: processors, memory, PCI Express
I/O and legacy I/O subsystems. It supports dual
Intel Xeon processors up to 3.2 GHz as well as
Low Voltage Intel Xeon processors with 800 MHz
system bus with 1 MB L2 cache, delivering
bandwidth up to 6.4 GB/second.
Memory
Intel E7520 chipset-based platforms can be
designed to support DDR 266, DDR 333 or
DDR2-400. DDR2-400 memory technology
is ideal for storage and memory-intensive
applications, providing up to 20% increase in
memory bandwidth, and up to 40% decrease in
power consumption over DDR 333. The memory
subsystem interface to the MCH is dual channel,
supporting three or four registered DIMMs per
channel—depending on memory technology—
for a total system bandwidth of up to 6.4
GB/second. The MCH supports up to 16 GB for
DDR2-400 memory, up to 32 GB for DDR 266,
and up to 24 GB for DDR 333.
