Find processor Product Codes:


Board Revision Note : A small bar-coded label, similar to the diagram shown below, can be found on the component side of the desktop board. The numbers following the letters "AA" can help identify the type and version of your desktop board. The AA contains a 6 digit main number, and a 3 digit dash number (the 3 numbers following the "-").

The statement "...or later" refers to the dash number of the AA (the three numbers following the "-"). If this number is greater than the number listed in the table, the board supports the associated processor(s).

If your 6 digit main number is not listed in the table, contact your system manufacturer for processor support information.




The sSpec number is also known as specification number. It is a five character string (SL36W, XL2XL, etc.) that is printed on the processor, and used to identify the processor. You can find this number by looking at the markings on the processor or on the label that came with your boxed processor.

Warning: Processors not specifically listed by type and rated speed may have requirements that are not supported by the desktop board's design. Use of unsupported processors may result in improper operation, damage to the desktop board or processor, or reduced product life. Except as provided in Intel's Terms and conditions of Sale for such products, INTEL ASSUMES NO LIABILITY WHATSOEVER, AND INTEL DISCLAIMS ANY EXPRESS OR IMPLIED WARRANTY, RELATING TO SALE AND/OR USE OF THE INTEL PRODUCTS INCLUDING LIABILITY OR WARRANTIES RELATING TO FITNESS FOR A PARTICULAR PURPOSE, MERCHANTABILITY, OR INFRINGEMENT OF ANY PATENT COPYRIGHT OR OTHER INTELLECTUAL PROPERTY RIGHT.
