Intel I/O Controller Hub (ICH). The DMI is equivalent to a x4 PCIe Gen1 link with a transfer rate of 1 Gb/s

in each direction.

PCI Express Generation 2

PCI Express is a serial point-to-point interconnect for I/O devices. PCIe Gen2 doubles the signaling bit

rate of each lane from 2.5 Gb/s to 5 Gb/s. Each of the PCIe Gen2 ports are backwards-compatible with

Gen1 transfer rates.

In the Tylersburg-36D IOH, there are two x2 PCIe Gen2 ports (1Gb/s) and eight x4 PCIe Gen2 ports (2

Gb/s).Thex2portscanbecombinedasax4link;however,thisx4linkcannotbecombinedwithanyof

the other x4 ports. Two neighboring x4 ports can be combined as a x8 link, and both resulting x8 links

can combine to form a x16 link.
