CPU-Z is more in-depth in some areas than the features that Windows XP provides to identify various hardware components, and is thus needed to identify certain components without opening the case, especially the core revision and RAM clock rate.
It has an unusual ability to directly detect hardware features, especially the ability to access, read and display the SPD data from memory modules. The ability to document clock speed makes it an important tool for motherboard overclockers, as a way of proving the CPU speeds achieved by various experiments.
This software is a portable application — installation does not generate complex interdependencies with the operation system; the resulting executable file can simply be copied to any data storage device and executed on any Windows computer.
