Issue Details

  • I have an NI PCIe (PCI Express) card and I want to know how many bus lanes it uses.
  • In my Development PC I have few PCIe slots: x1, x4, x8, x16. Some of them are taken, how can I check if my card is compatible with these interfaces?

Solution

A. You can know your device's PCIe lanes in the following ways:
  1. By checking the Specification Sheet of the device, and looking under the Bus Interface section.
  2. By checking the connector size of the card in its product page.
For example: The PCIe-6509 showcases an X1 connector form factor.

B. You can know the compatibility of your card by checking the Specification Sheet, or following the guide located in: Select the Right PC for Your PCI Express Hardware
For example: The PCIe-6361 supports x1, x4, x8, and x16 PCI Express slots. Please see the Bus Interface section within the Device Specification for more information (page 16).
 

Additional Information

  • Higher bandwidth slots e.g. 4x, 16x are working properly with lower bandwidth cards.
  • Some motherboards reserve the x16 slot for graphics use.
