0146-PCI Out of Resource Error for Intel® Server Board Product Families


Maintenance & Performance



When an Intel® Xeon Phi™ Coprocessor or multiple PCI Express* (PCIe*) adapters are installed, the following error can display during POST, and the server halts: 0146 - PCI out of resource

To resolve the issue, follow these steps:

  1. Temporarily remove the add-on PCI Express adapters.
  2. Update the BIOS and firmware to the latest revision.
  3. Disable any unused devices and Option ROMs in the BIOS.
    1. For onboard SATA/SAS controllers, go to Advanced > Mass Storage Controller Configuration.
    2. For onboard NICs, go to Advanced > NIC Configuration.
  4. Go to Advanced > PCI Configuration.
    • Set Maximize Memory below 4 GB to Disabled.
    • Set Memory Mapped I/O above 4 GB to Enabled.
    • Set Memory Mapped I/O Size to 256 G or higher, for an Intel® Xeon Phi™ Coprocessor. For other PCIe Adapters, use an appropriately large value.
  5. Install the add-on PCI Express adapters one at a time and see if the server boots properly.
