SYMPTOMS
When you run the Windows NT Diagnostics program in Windows NT 4.0 or the System Information tool in Windows 2000 and then try to view your computer's CPU speed, the displayed speed may differ from the actual speed of the CPU currently installed. For example, a computer with an Intel Pentium-II processor rated at 266 Megahertz (MHz) may be displayed as "x86 Family 6 Model 3 Stepping 4 GenuineIntel ~264 MHz".



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
The tilde ("~") that prefaces the CPU speed indicates that this is an approximate measurement.
