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, Mobile Intel® Pentium� 4, Pentium III, Mobile Pentium III with Intel SpeedStep" technology, Pentium III Xeon" and Intel Celeron® processors with 66, 100, and 133 MHz system memory bus products, as well as adding new processor identification functionality (CPUID). Please see the supported processors list for more detail.
There are two versions of the utility available. The Windows version of the utility can be used with systems that support the Windows operating system environment. The "Bootable" version of the utility does not require an operating system. By installing the tool on a bootable device (e.g. floppy drive) the tool is run as the system is booted, but before the PC's operating system is loaded. This is normally done from a PC's floppy "A:" drive.
