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 2.0 x1: two PCI Express 2.0 x1 connectors. The x1 interface supports
•
simultaneous transfer speeds up to 2.5 Gb/s of peak bandwidth per direction and
up to 5.0 Gb/s concurrent bandwidth.
PCI Conventional (rev 2.3 compliant) bus: three PCI Conventional bus add-in card
•
connectors.
Note the following considerations for the PCI Conventional bus connectors:
The PCI Conventional bus connectors are bus master capable.
•
SMBus signals are routed to the PCI Conventional bus connectors. 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.
