Note
  • 2D matrix (or 2DID, or 2D barcode) is on the topside of the processor, that is, marking on the IHS (integrated heat spread) of the processor.
  • 2nd copy of the 2DID is added on the bottom-side starting with the 4th Gen Xeon (Sapphire Rapids) processors for server and workstation including boxed processor SKUs.
  • Processor manual covers the details.

 

Note

Use the Intel® Processor Identification Utility – Windows* version to identify the specifications of your processor. Also, review the sockets that are supported by your processor.

The following information helps you identify server processor markings. Processor markings let customer support know if you are eligible for a warranty exchange.

Note Intel® Xeon® Scalable Processors are dictated by the manufacturer.

Where do I find the processor markings?

All Intel® Xeon® Scalable Processors have markings inscribed on the top of the processor package. The most recent Intel® Xeon® Scalable Processors packages and markings are described here.

The serial number is required for warranty processing. The serial number of a processor is typically a combination of the finished process order (FPO) number and the assembly test process order (ATPO) number. If the ATPO Number is not present, provide the FPO number.

If you have the FPO number and ATPO numbers in hand, check your warranty coverage online at the Warranty Center.

If you are not sure about the processor package or socket for your processor, collect the processor markings and Contact Support.

4th Generation Intel® Xeon® Scalable Processors

On the 4th Generation Intel® Xeon® Scalable Processors, a change was made on the markings, as in the example below:

Note These are only examples for orientation purposes. The number will not match any Production product.

Scan PPIN Scan for Vis_ID
Scan PPIN M26P8K1400671

For Boxed 4th Generation Intel® Xeon® Scalable Processors, the Serial Number on the box will be matching the Serial Number engraved on the CPU:

There is also a 5 number digit on the internal side of the 4th Generation Intel® Xeon® Scalable Processors which is used for internal control and will not match any Box information.
