2.2.2.2 Add-in Card Connectors

The board has the following add-in card connectors:

• PCI Express x16: one connector supporting simultaneous transfer speeds up to

4 GBytes/sec of peak bandwidth per direction and up to 8 GBytes/sec concurrent

bandwidth.

• PCI Express x1: two PCI Express x1 connectors. The x1 interface supports

simultaneous transfer speeds up to 250 Mbytes/sec of peak bandwidth per

direction and up to 500 MBytes/sec concurrent bandwidth.

• PCI Conventional (rev 2.3 compliant) bus: one PCI Conventional bus add-in card

connector. PCI Conventional bus add-in cards with SMBus support can access

sensor data and other information residing on the board.

Note the following considerations for the PCI Conventional bus connector:

• The PCI Conventional bus connector is bus master capable.

• SMBus signals are routed to the PCI Conventional bus connector. This enables PCI

Conventional bus add-in boards with SMBus support to access sensor data on the

board. The specific SMBus signals are as follows:

⎯ The SMBus clock line is connected to pin A40.

⎯ The SMBus data line is connected to pin A41.
