Technical specifications
PCIe®specifications
The primary I/O bus for the main board is PCIe Gen2. The following table lists the characteristics of the
PCI-E bus segments. Details about each bus segment follow the table.
NOTE: The signaling bit rate of PCI Express is 2.5Gbit/s one direction per lane for Gen 1 and 5.0Gbit/s one
direction per lane for Gen 2.

NOTE:
1. Indicates the number of physical electrical lanes running to a PCIe® connector.
2. Default bus assignment (in decimal). Inserting cards with PCI™ bridges may alter the actual bus
assignment number.
3. Slots are enumerated differently based on the operating system. Microsoft® operating systems
enumerate Device ID by bus starting from the lowest bus to the highest.
