The Intel® Processor Frequency ID Utility was developed by Intel Corporation to enable consumers with the ability to identify and in some circumstances determine if their Intel processor is operating at the rated frequency intended by Intel Corporation. Beginning with the Pentium® III processor, the Intel Processor Frequency ID Utility has the capability to provide actual and intended frequency, or speed, information.
The Specification Update and Product Specifications and Comparisons are resources which contain information about the different steppings and versions of processors. If you need information about the voltage, thermal specifications, the processor packaging, or other information about a particular Pentium III processor, you will need to view the part numbers on your processor and compare that information with the Specification Update or the Product Specifications and Comparisons tool.
The Specification Update is a document that has more complete information, but the Product Specifications and Comparisons tool may be a bit easier to use.
The Product Specifications and Comparisons tool was designed as a reference to help you look up technical spec information on your Intel® processor. To find the information that you are looking for, you will need to know your processor's sSpec number.
Package Markings: Single Edge Contact Cartridge (S.E.C.C.)
The Pentium III processor's S.E.C.C. cartridges have laser etched markings that indicate the processor's core speed, L2 cache size, S-spec number, serialization code, and country of origin. The markings are located on top of the cartridge. Refer to the Specification Update for more details.
