2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
• One PCI Express x16 connector:
⎯ Supports PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each
direction (500 MB/s total). The maximum theoretical bandwidth on the
interface is 4 GB/s in each direction simultaneously, for an aggregate of 8 GB/s
when operating in x16 mode.
• PCI Express x1: one PCI Express x1 connector. The x1 interface supports
simultaneous transfer speeds up to 250 Mbytes/sec of peak bandwidth per
direction and up to 500 MB/sec concurrent bandwidth.
• PCI Conventional (rev 2.3 compliant) bus: two 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.
