What is CPU-Z

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

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

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.
• The kernel mode driver used by CPU-Z is installed on the system, that avoids to install / remove it at every run. That makes the process more stable and slightly faster.

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. 

Special Keys
The F5 key allows to save 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 to gather 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.
