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 the Product Specifications and Comparisons tool 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: Flip-Chip Pin Grid Array (FC-PGA)/FC-PGA2
These markings are located on the top side of the package. On one edge, the copyright, country of origin, speed of the processor, cache size, bus speed of the processor and voltage. On the opposite edge are the FPO serialization number, production specification (sSpec) number and the branding of the processor. Refer to the Specification Update for more detailed information. The FC-PGA2 packages are similar to the FC-PGA package except the FC-PGA2 use an Integrated Heat Spreader (IHS) that covers the die.
Package Markings: Single Edge Contact Cartridge(S.E.C.C.) and Single Edge Contact Cartridge 2(S.E.C.C.2)
The Pentium III processor's S.E.C.C. and S.E.C.C.2 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.
