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: three 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: two 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.
