How to Obtain Warranty Service
To obtain warranty service for your
AMD Processor in a Box, contact your computer system manufacturer or distributor during the systems warranty period. After your computer system warranty has expired, you can submit a warranty request to AMD Customer Care. To submit a warranty claim visit *
http://support.amd.com/en-us/warranty.
Please be prepared to provide: (1) your name, address, and telephone numbers;
(2) proof of purchase; (3) a description of the type of boxed processor;
(4) the serial number found on your boxed processor and; (5) a description of the computer system including the brand and model; (6) an explanation of the problem; and (7) your election to accept return of the processor to you, at your cost, if AMD determines the processor is not covered by the limited warranty or to consent to AMD’s destruction of the part. The AMD Customer Care Representative may need additional information from you depending on the nature of the problem and all requested information must be provided before AMD will process any RMA request.
Upon receipt of a Return Material Authorization (RMA) number from a Customer Care Center Representative, you will be required to send in your processor.
If requested by AMD, you will also be required to send in the heatsink/fan that was packaged with your processor. The packaging materials themselves will not be required to process your RMA. If AMD, in its sole discretion, determines that the processor is not covered by the AMD limited warranty, AMD will return or destroy the processor pursuant to your election.
Above is for boxed CPU
AMD probably detected that the buyer wasn't sold a boxed CPU. In fact at this point the buyer might have been sold a fake CPU for all we know.
