Add-in Card Connectors
The board has the following add-in card connectors:
• PCI Express x16: one connector supporting simultaneous transfer speeds up to 8 GBytes/sec
• PCI Express x1: the D915PCY board has two PCI Express x1 connectors; the D915PCM
• PCI Express x16: one connector supporting simultaneous transfer speeds up to 8 GBytes/sec
• PCI Express x1: the D915PCY board has two PCI Express x1 connectors; the D915PCM
board has one PCI Express x1 connector. The x1 interfaces support simultaneous transfer
speeds up to 500 MBytes/sec
speeds up to 500 MBytes/sec
• PCI Conventional (rev 2.2 compliant) bus: the D915PCY board has four PCI Conventional
bus add-in card connectors; the D915PCM board has two PCI Conventional add-in card
connectors. The SMBus is routed to PCI Conventional bus connector 2 only (ATX expansion
slot 6). PCI Conventional bus add-in cards with SMBus support can access sensor data and
other information residing on the Desktop Board.

Note the following considerations for the PCI Conventional bus connectors:
• All of the PCI Conventional bus connectors are bus master capable.
• SMBus signals are routed to PCI Conventional bus connector 2. This enables PCI

Conventional bus add-in boards with SMBus support to access sensor data on the boards. The
specific SMBus signals are as follows:
specific SMBus signals are as follows:
The SMBus clock line is connected to pin A40.
The SMBus data line is connected to pin A41.
