Hmmm... I would first look at this: Where Can I Find Intel® Boxed Processors and Fan Part Numbers?
Then, I would run this: Support for Intel® Processor Identification Utility
Then, I would run this: The Intel® Processor Diagnostic Tool
After all of that, if I still had a doubt, I would probably return the processor.
- Go to Warranty Information
- Under product type, select processor.
- In the "FPO Number" field, please type the Batch number located on the white sticker on the box.
- In "ATPO Serial Number" please type the S/N located on the same white sticker.
- Click on "Check Products"
If the website shows the model number of your processor along with the approximated warranty expiration date, it means that is a valid Intel® Core™ i7-7700 Processor.
*Please don't share the FPO/ATPO combination in this thread.
Please let me know how it goes.
I will take the tool approach.
Has there any fake processor(s) been made to pass tool approach in the past?
The tools will confirm the processor type and specs and The Intel® Processor Diagnostic Tool will tell you if it is a genuine Box or Tray processor.
However, it will not be a guarantee against a counterfeit unless the results differ from what you expected (i.e.: remarked processor).
The best way to confirm the processor's validity is with the FPO and ATPO Serial Number on the Warranty Center (provided above). This will validate the processor and the warranty options. For serial numbers not human-readable, you will have to rely on the Retail box.
I hope this is helpful.
