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.
