Add-in Card Connectors
The board has the following add-in card connectors:
•
PCI Express 2.0 x16: one PCI Express 2.0 x16 connector supporting simultaneous
transfer speeds up to 8 GB/s of peak bandwidth per direction and up to 16 GB/s
concurrent bandwidth.
•
PCI Express 1.1 x1: two PCI Express 1.1 x1 connectors. The x1 interface
supports simultaneous transfer speeds up to 250 MB/s of peak bandwidth per
direction and up to 2 GB/s concurrent bandwidth.
•
PCI Conventional (rev 2.3 compliant) bus: one PCI Conventional bus add-in card
connector.
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
desktop 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.
