The Intel® E7520 includes revolutionary PCI Express*1 serial I/O technology and DDR2, the next generation memory technology, to help increase I/O bandwidth and reduce system latency for data-intensive applications. The 800 MHz system bus allows these chipsets to support the Intel® Xeon® processor as well as the Low Voltage Intel® Xeon® processor with 800 MHz system bus with Intel® Extended Memory 64 Technology (Intel® EM64T), Hyper Threading technology, Enhanced Intel SpeedStep® Technology and Streaming SIMD Extensions 3 (SSE3) Instructions.
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.
