How to Identify My Intel® Xeon® Processor Markings for Warranty Requests
| Note: |
|
| 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.

Intel® Xeon® 6 Processors
On Intel® Xeon® 6 the marks are on the examples below:
| Note: | The image below depicts a pre-production CPU and does not represent the final production version. |
| Line | Top Side Marking |
| Line 1 | Intel Logo |
| Line 2 | INTEL Brand |
| Line 3 | N/A (SKU level/Naming) |
| Line 4 | Spec Code (QDF/SSPEC) |
| Line 5 | (FPO) |
| Line 6 | Human Readable (SubMark Content) |
| Line 7 | IHS 2D Mark (PPIN+QDF/SSPEC+FPO) |
| Line 8 | Package Carrier |
| Line 9 | PIN1 Mark on Lid |
| SubMark | Randon Number |
| Bottom 2D Mark | PPIN+ SSPEC+FPO |
On the orders for Intel® Xeon® 6 the word INTEL will automatically print on the labels and is hard coded in iLabel.
| Note: | There is a 3 character on the right side of the 2D Mark (see example) that is a random number used for internal controls. This number is not linked to any SKU specification or CPU feature. |
4th and 5th Generation Intel® Xeon® Scalable Processors
On the 4th and 5th Gen Intel® Xeon® Scalable Processors, a change was made on the markings, as in the example below:
| Note: | The image below depicts a pre-production CPU and does not represent the final production version. |
| Scan PPIN | Scan for Vis_ID |
 | M26P8K1400671 |
| Line | Top Side Marking |
| Line 1 | Intel Logo |
| Line 2 | Intel Brand |
| Line 3 | SKU level/Naming |
| Line 4 | Spec Code (SSPEC) |
| Line 5 | (FPO) |
| Line 6 | Package Carrier |
| Bottom SubMark | Randon Number |
| Bottom 2D Mark | PPIN+ SSPEC+FPO |
There is also a 5-digit number on the internal side of the 4th and 5th Gen Intel® Xeon® Scalable Processors, which is used for internal control and will not match any Box information.
