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 D915GAV board has two PCI Express x1 connectors; the D915GAG 

board has one PCI Express x1 connector.  The x1 interfaces support simultaneous transfer 
speeds up to 500 MBytes/sec. 

•  PCI Conventional (rev 2.2 compliant) bus:  the D915GAV board has four PCI Conventional 

bus add-in card connectors; the D915GAG 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: 
  The SMBus clock line is connected to pin A40. 
  The SMBus data line is connected to pin A41.
