You can properly identify a processor by running the Intel® Processor Identification Utility.
You can download the Intel® Processor Identification Utility at:
If you are referring to physically identify the processor, I would suggest also calling the local support center at:
And providing them all the information on top of the processor, so the customer service agent will be able to determine if it is an original processor from Intel.
