Technical Reference 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 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 2.5 Gb/s of peak bandwidth per direction and up to 5.0 Gb/s concurrent bandwidth. • PCI Conventional (rev 2.3 compliant) bus: one PCI Conventional bus add-in card connector. Note the following considerations for the PCI Conventional bus connector: • The PCI Conventional bus connector is bus master capable. • SMBus signals are routed to the PCI Conventional bus connector. This enables PCI Conventional 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. 2.2.2.3 Power Supply Connectors The board has the following power supply connectors: • Main power - a 2 x 12 connector. This connector is compatible with 2 x 10 connectors previously used on Intel Desktop boards. The board supports the use of ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables. When using a power supply with a 2 x 10 main power cable, attach that cable on the rightmost pins of the main power connector, leaving pins 11, 12, 23, and 24 unconnected. • Processor core power - a 2 x 2 connector. This connector provides power directly to the processor voltage regulator and must always be used. Failure to do so will prevent the board from booting. Table 18.

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 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 2.5 Gb/s of peak bandwidth per direction and
up to 5.0 Gb/s concurrent bandwidth.
•
PCI Conventional (rev 2.3 compliant) bus:
one PCI Conventional bus add-in card
connector.
Note the following considerations for the PCI Conventional bus connector:
•
The PCI Conventional bus connector is bus master capable.
•
SMBus signals are routed to the PCI Conventional bus connector.
This enables PCI
Conventional 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.
2.2.2.3
Power Supply Connectors
The board has the following power supply connectors:
•
Main power
– a 2 x 12 connector.
This connector is compatible with 2 x 10
connectors previously used on Intel Desktop boards.
The board supports the use
of ATX12V power supplies with either 2 x 10 or 2 x 12 main power cables.
When
using a power supply with a 2 x 10 main power cable, attach that cable on the
rightmost pins of the main power connector, leaving pins 11, 12, 23, and
24 unconnected.
•
Processor core power
– a 2 x 2 connector.
This connector provides power
directly to the processor voltage regulator and must always be used.
Failure to do
so will prevent the board from booting.
