When you configure detection toolsdetectors, select Nvidia GPUs one by one.

Note
titleAttention!
  • If only one Nvidia GPU is installed, select Nvidia GPU 0.
  • If several Nvidia GPUs are installed, select the graphics card on which you want to perform the detection process.
  • If you select an uninstalled Nvidia GPU, detection isn't performed.

The table lists the parameter names and detection toolsdetectors, configuring which you can select the required Nvidia GPU:

You can change the order of the Nvidia GPU display using the CUDA_DEVICE_ORDER system variable (see Appendix 9. see Creating system variable) by specifying the required value:

  1. The FASTEST_FIRST value numbers the GPUs from the most powerful card to the less powerful ones, that is, Nvidia GPU 0 is the most powerful card.
  2. The PCI_BUS_ID value numbers the GPUs according to the physical location of the cards in the PCI-E slots on the motherboard, that is, Nvidia GPU 0 is the card in the highest slot.

To find out information about the availability, quantity, and numbering of Nvidia GPUs, do the following: 

  1. Run the command prompt as administrator.
  2. In the command prompt, enter the Nvidia-smi query.
  3. Press Enter.

The command prompt window displays the information about the installed Nvidia GPUsGPUs.
