Insufficient PCIe resources are detected.

If you see an error message stating “Insufficient PCI Resources Detected,” complete the following steps until the problem is resolved:

  1. Remove one of the PCIe adapters.

  2. Restart the system and press F1 to display the Lenovo XClarity Provisioning Manager system setup interface.

  3. Click UEFI Setup > System Settings > Devices and I/O Ports > MM Config Base; then, modify the setting to the lower memory capacity. For example, modify 3 GB to 2 GB or modify 2 GB to 1 GB.

  4. Save the settings and restart the system.

  5. The action for this step will differ based on whether or not the reboot is successful.

    • If the reboot is successful, shutdown the solution and reinstall the PCIe card you removed.

    • If the reboot failed, repeat step 2 to step 5.
