The Intel Processor Frequency ID Utility was developed by Intel Corporation to enable consumers the ability to identify and, in some circumstances, determine if their Intel processor is operating at the correct and rated frequency intended by Intel Corporation. Beginning with the Pentium® processor, this utility provides consumers with the ability to determine standard CPU identification of Intel processors. In addition, supported processors can utilize the Frequency Test feature of the utility to help determine if a processor has been overclocked. This version of the Intel Processor Frequency ID Utility has been updated to support the new Intel Xeon Processor, Pentium 4 processors, Mobile Intel Pentium 4 processors, Pentium III processors, Mobile Pentium III processors with Intel SpeedStep technology, Pentium III Xeon processors and Intel Celeron processors with 66, 100, 133, 400, 533 , and 800 MHz system memory bus products, as well as adding new processor identification functionality (CPUID).
