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?epending 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. product brief
pci express* 1 for demanding i/o and networking applications, pci express interfaces attach a variety of intel and third-party i/o solution components and adapters directly to the mch at throughput speeds of up to 4 gb/second on each x8 interface, allowing i/o to keep pace with the rest of the platform. the intel E7520 mch has three x8 pci express interfaces which can each be bifurcated into two x4 interfaces for additional configuration flexibility. intel 6300esb i/o controller hub available as the i/o controller hub for legacy i/o support, the intel 6300esb i/o controller hub (ich) attaches directly to the mch through the intel hub interface 1.5 connection at 266 mb/second. for the most demanding storage data transfers and support for optional third-party software raid 0, 1 technology, the intel 6300esb ich integrates dual independent sata controllers with 32-bit pci connectivity, each capable of up to 150 mb/second transfer rate. four hi-speed usb 2.0 ports allow easy i/o connection, while offering improved bandwidth compared to usb 1.1 devices. unlike the intel 82801er i/o controller hub (ich5r), the intel 6300esb ich includes a pci-x* 64/66 bus supporting up to four pci-x 64/66 mhz devices. optional intel 6700pxh 64-bit pci hub the intel 6700pxh 64-bit pci hub connects to the mch through a point-to-point x8 or x4 pci express interface. each hub contains two bus segments that can be independently configured to operate in pci (33 or 66 mhz) or 64-bit pci mode 1 (66, 100, or 133 mhz), for either 32-bit or 64-bit pci/pci-x devices. in addition, each intel 6700pxh 64-bit pci hub integrates two pci standard hot plug controllers?ne per pci/pci-x interface?nd can be independently configured up to two pci-x 64/133 mhz segments. the intel 6700pxh 64-bit pci hub supports multiple pci-x slots and frequencies for high-bandwidth i/o connectivity. intel ?
