4.1  (335 votes)

CPU-Z is a free application developed to provide us with exhaustive information about our computer's inner works: processor, operating system, CPU, BIOS, graphic interface, memory, and so on.
The program's interface is divided into seven tabs, each one giving comprehensive information on one particular item: CPU, caches, mainboard, memory, SPD, graphics, and program information (which includes detailed information about our installed Windows operating system). We can use this program to know the exact model of the processor we have installed, the BIOS brand, version, and date; the graphic interface details, including the memory size, type, channels, and timings (DRAM frequency, CAS# latency and delay, RAS3 precharge, cycle time, etc.). This program also displays details about our computer's memory slot selection, timings table, GPU name, clocks core, shares, and memory size, type, and bus width. The displayed report can be saved either as a TXT or an HTML file. Optionally, this information can even be published online.

There are four completely free downloadable versions of this program: the first one includes an executable file for both 32-bit and 64-bit versions of Windows. The second and the third ones are zipped files for 32-bit and 64-bit versions separately, without any installation. The last one is a zipped file for Windows 98 OS.
