Step 1 – Determine if Your Product Is Really Defective

Take a moment to review the suggestions below to be certain the processor is indeed defective. Often, the cause of the problem is not the processor itself.

  1. Visit the motherboard manufacturer's website and check that the processor is fully supported by the motherboard. New processors may require a motherboard BIOS update to correctly recognize a new processor.

    For a list of supported processors per BIOS version, please refer to the CPU Support List document available on your motherboard manufacturer's website:

    On your motherboard manufacturer’s website, make the appropriate selections to view the BIOS version required to support your CPU.  BIOS download and installation instructions are also found on their website.

    For more information, watch this video on how to update motherboard BIOS.
  2. Check that the memory installed is supported by your motherboard. Most motherboard manufacturers publish a list of tested and approved memory.
  3. Make sure that all power connectors are properly connected and that your power supply is sufficient for your system.  For more information, please refer to KB article: How to Troubleshoot System Stability Issues Caused by the Power Supply Unit
  4. If possible, try testing the processor in another compatible system to verify that the processor is indeed faulty. 

    For information on how to correctly install or replace your processor, please watch this video:
    Note! It is important to always use proper care when handling the processor.  Please refer to our Processor Handling Guidance page for tips and best practices. 

Step 2: Determine What Is Not Covered by Warranty

  1. Try to determine if your processor defect is covered by warranty (see examples below). AMD is not liable under warranty if, through testing and examination, it is AMD’s reasonable opinion that the alleged defect or malfunction of the CPU has been caused by misuse, neglect, improper installation or testing.
  2. Remove the processor from the other components before you return it. Warranty service requires that only the processor be returned. Do not return the heat-sink and fan that was packaged with your processor. Upon receipt of the processor, AMD will inspect for mechanical damage and test it.

    Common examples not covered by warranty:

    Chips and Cracks

    Bent and/or Damaged Pins

    Burnt and/or Heated Damaged Processor

Step 3 – Provide Required Product Information

You should include the following product information in your warranty service request:

  • Processor’s Model Number.  Also known as the OPN.
  • Processor’s Serial Number

The Processor’s Model Number and Serial Number can be found on the box, on the processor’s surface and in the instruction book.


Continue to Step 4: Request Warranty Service

An email will be sent to you with further instructions on how to proceed with sending in your defective processor. Be certain to send only the processor. The heat-sink and all other original packaging is not required.
