How to Identify a Boxed vs. an OEM Processor

Intel sells processors through retail stores, such as Best Buy, Fry’s, your neighborhood computer shop, etc. and wholesale channels such as Hewlett-Packard, Dell, Gateway, etc. or resellers. The wholesale channels are often referred to as original equipment manufacturers (OEMs).

Retail processors are sold in clearly marked individual boxes and typically carry a 3-year warranty directly from Intel.

Wholesale processors are not sold in retail boxes and are typically pre-installed by an OEM or reseller. Intel ships the processors to OEMs in trays so we refer to these types of processors as OEM/Tray processors.

Intel does not provide direct warranty support for wholesale processors. If your processor was sold through an OEM or reseller, you must contact your OEM or reseller for warranty support. Also, see the Intel Warranty Guide for Processors video.

If you are not sure who to contact, find the fan/heatsink and processor markings (see below) and contact Intel.

If your system is newer than 3 years, you may go to the Intel Boxed Processor Verification website to identify if your processor is a boxed vs. an OEM processor. For Intel China boxed processors, please go to Intel China Boxed Processor Verification website.

Note It is important to have both fan and processor markings when you contact Intel Customer Support. Specific fan/heatsinks are shipped with most processors, certain fan/heatsinks may not work with all processors. Mobile and Some Enthusiast SKUs (Unlocked Processors) do not ship with a fan/heatsink or Thermal Solution.

Fan/Heatsink markings
Record the part number and manufacturer from the top of the fan. The part number is generally the first number found and starts with a 'D' 'E' or 'C'. The manufacturer is located near the bottom of the label (for example, Nidec, Fujikura, Sanyo-Denki, Delta).

Processor markings
Record the processor markings from the physical processor. The markings on the box label are not sufficient. The information you need is identified in example 2 and 3.

Figure 2 details the general markings used for most current Intel® Processors. Figure 3 shows the markings for older processors. The location of certain markings (for example, Processor #) vary based on the type of processor you have.
