2.2.2.2 Add-in Card Connectors
The board has the following add-in card connectors:
PCI Express 2.0 x16: two PCI Express 2.0 x16 connectors 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 1 GB/s of peak bandwidth per direction and up
to 2 GB/s concurrent bandwidth.
Conventional PCI (rev 2.3 compliant) bus: three Conventional PCI bus add-in card
•
connectors.
Note the following considerations for the Conventional PCI bus connector:
The Conventional PCI bus connectors are bus master capable.
•
SMBus signals are routed to the Conventional PCI bus connectors. This enables
•
Conventional PCI 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.
