The Product Specifications and Comparisons tool was designed as a reference to help you look up technical specification information on your Intel® Xeon® Processor. To find technical specifications, you'll need to know your processor's sSpec number.
Need help finding your sSpec number?
The sSpec number is also known as specification number. It's a five character string (SL36W, XL2XL, and so on) printed on the processor and used for identification. You can find this number by looking at the markings on the processor (see Figure 2), or on the boxed processor label. See Figure 1 below for an example of how to read the label to find your sSpec number.
