Add-In Card Connectors - Intel DQ67OW Specification

2.2.2.2

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. This connector supports
simultaneous transfer speeds of up to 8 GB/s of peak bandwidth per direction.
• PCI Express 2.0 x4: one PCI Express 2.0 x4 connector. The x4 interface supports
simultaneous transfer speeds up to 500 MB/s of peak bandwidth per direction and
up to 4 GB/s concurrent bandwidth.
• PCI Express 2.0 x1: one PCI Express 2.0 x1 connector. 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.
• One Conventional PCI (rev 2.3 compliant) connector.
Note the following considerations for the Conventional PCI bus connector:
• The Conventional PCI bus connector is bus master capable.
• SMBus signals are routed to the Conventional PCI bus connector. 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.
