What is CPU-Z?

CPU-Z is a freeware that gathers information on some of the main devices of your system.

The CPU-Z's detection engine is now available for customized use through the CPUID System Information Development Kit, a professional SDK built for the Microsoft Windows operating systems.

CPU

• ·        Name and number.
• ·         Core stepping and process.
• ·         Package.
• ·         Core voltage.
• ·         Internal and external clocks, clock multiplier.
• ·         Supported instruction sets.
• ·         Cache information.

Mainboard                                                                                                                                  

• ·         Vendor, model and revision.
• ·         BIOS model and date.
• ·         Chipset (northbridge and southbridge) and sensor.
• ·         Graphic interface.

Memory

• ·         Frequency and timings.
• ·         Module(s) specification using SPD (Serial Presence Detect) : vendor, serial number, timings table.

System

• ·         Windows and DirectX version.

Install & configuration

Install and Remove
Since version 1.51, CPU-Z includes an installer. The installation offers several advantages in comparison to the stand-alone version:

• The installation creates program entries in the start menu and on the desktop.
• It installs the right binary (x32 or x64) depending on your system.

Installation 

• Run the setup executable file, and let it guide you for the installation process.

Removal 

• You can remove the program either from the Add or Remove Programs window (from Settings, Control Panel), or choose Uninstall CPU-Z from Start menu, Programs, CPUID, CPU-Z.

Configuration file 

• CPU-Z uses a configuration file, cpuz.ini that allows setting several parameters for the program. The cpuz.ini file must be in the same directory as cpuz.exe.

Special Keys 

• ·         The F5 key allows saving a screenshot as a bmp file in the application directory. These are named cpu.bmp, cache.bmp, mainboard.bmp and memory.bmp.

• ·         The F6 key copies the current page in the clipboard.

• ·         The F7 key saves the validation cvf file in the current directory.

• ·         The F9 key switches between CPU clock computation methods.

Cache Latency Computation
The cache latency computation tool allows gathering information about the cache hierarchy of the system. For each cache level, it provides its size and its latency. Please note that code caches are not reported.
