AMD K8 S754 MS  (Week ??, Year 2003)   

This sample is a non-fonctional CPU known as "Mechanical sample". It looks like a standard Socket 754 CPU, but it was only intended for testing or demonstration. It could be used on all Socket 754 motherboards to test the fixation of heatsinks. This mecanical sample seems to be an electrical sample too because it is able to POST but crash before the end of the boot process.
