RAID Card Not Detected for Some Intel® Server Systems


Slot limitation with the single processor for Intel® Server Systems.


If the RAID card is installed in Riser 2, or in the bottom slot of Riser 1, with only one CPU installed, the following happens:

  • The Intel® RAID Controller is not detected.
  • ​The system reports adapter not found.
  • First make sure that the board and card combination are compatible.
  • If there is only one CPU installed in the Dual Socket system:
    • Use the top slot of Riser 1 for controllers or adapters.
  • On single-socket Boards
    • Clear the event log, load the Default Settings in the BIOS, and restart the system.
    • Confirm that Quiet Boot in BIOS, under the Main Menu, is set to Disabled.
      • If enabled, you may not see the POST prompt message to enter the RAID Card BIOS.

An additional task that may be useful is to clear the CMOS:

  1. Shut the system down.
  2. Unplug the power cord.
  3. Open the chassis lid
  4. Locate and remove the Real Time Clock (RTC battery) and leave it out for at least 2 minutes.
  5. Insert the battery
  6. Plug in the power cord
  7. Close the chassis cover
  8. Power on the system.

Check and see if the RAID card is detected. If necessary, go into the BIOS Setup Utility and reset any customized BIOS settings again.
