3.3 Intel

5520 Chipset IOH

The Intel

5520 Chipset component is an I/O Hub (IOH.) The Intel

5520 Chipset IOH provides

a connection point between various I/O components and Intel processors through the Intel

QPI

interface.

The Intel

5520 Chipset IOH is capable of interfacing with up to 36 PCI Express* lanes, which

can be configured in various combinations of x4, x8, x16, and limited x2 and x1 devices.

The Intel

5520 Chipset IOH is responsible for providing a path to the legacy bridge. In addition,

the Intel

5520 Chipset supports a x4 DMI (Direct Media Interface) link interface for the legacy

bridge, and interfaces with other devices through SMBus, Controller Link, and RMII
manageability interfaces. The Intel

5520 Chipset supports the following features and

technologies:

Intel

QuickPath Interconnect (Intel

QPI)

PCI Express* Gen2

Intel

I/O Acceleration Technology 2 (Intel

I/OAT2)

Intel

Virtualization Technology (Intel

VT) for Directed I/O 2 (Intel

VT-d2)
