CPU-Z is a freeware that gathers information on some of the main devices of your system.
CPU-Z 1.56  improved the support of the latest Intel "Sandy Bridge", "Gulfton" and AMD "Caspian" processor in CPU-Z. It does now display the processor name and logo, as well as the memory frequency and timings.
News are :
- Intel Core i3/i5/i7 "2000" serie processors (Sandy Bridge) with new logos.
- Intel Core i7 970 "Gulftown".
- Intel P67 chipset.
- AMD Phenom II, Athlon II and Sempron II "Caspian" processors.

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. The setup installs a service, that is started the first time that you run CPU-Z. After that first run, you can run CPU-Z from any account, even without administrator privileges. 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. The latency tool can be downloaded here. Supported :

• VIA VX900/VX900M and VN1000/VN1000M chipsets.
• Intel Core i5-760, Core i7-875K and Core i5-655K processors.
• Intel Core i7-940XM, 840QM, 740QM mobile processors.
• Intel Core i5-450M, 540UM, 430UM, Core i3-370M mobile processors.
• Intel Pentium P6000 processor.
• New parameter in cpuz.ini : UseDisplayAPI
