2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
• One PCI Express x16 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: three 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: three PCI Conventional bus add-in card
connectors. The SMBus is routed to all PCI Conventional bus connectors. 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 connectors:
• All of the PCI Conventional bus connectors are bus master capable.
• SMBus signals are routed to all PCI Conventional bus connectors. 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.
