The Intel E7520 chipset platform configuration suits a wide range of price points and unique application environments. 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, PCI Express*1 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 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. standard hot plug controllers—one per PCI/PCI-X interface—and can be independently configured up to two PCI-X 64/133 MHz segments.
