The CACHE tab displays the L1 Data Cache, L1 Instruction Cache, L2 & L3 Cache. Although I didn’t find this tab much useful as all this info was already mentioned in the CPU tab under Cache.

The MAINBOARD tab showed the name of the Manufacturer, Model number, Chipset, Southbridge & Sensor under the Motherboard option. Under the BIOS option it shows the brand of the bios, its version and release date. Under the Graphic Interface it showed the type of Graphic Card it utilizes i.e. AGP or PCI-e, its Memory and transfer rate.

Here is a list of chipsets supported by it:

Intel i430TX, i440LX, i440FX, i440BX/ZX, i810/E, i815/E/EP/EM, i840, i845, i845E, i845G, i850/E, i845PE/GE, E7205(Granite Bay), E7500, E7520, i852, i855, i865P/PE/G, i875P, i915P/G, i915PM/GM, i925X/XE, i945P/PL/G/GZ, i945PM/GM/GT, i955X/XE, P965, Q965, G965, i975X, 5000X/P/Z, 5400A/B, P35, G33, G31, Q35, Q33, X38, X48, P45

NVIDIA® nForce, nForce2, nForce3, nForce4, nForce4 SLI Intel Edition, GeForce 6100/6150 (nForce 410/430), nForce 520/550/560/570/590, GeForce 7050/7100/7150, 650i, 680i, 750a/780a, 750i, 780i, 790i ;

ATi® RS350, RS400, RS480/RX480, RS482, RD580/RX580, RS600/RD600, RS690, RS700, RD790 ;
SiS® 645, 645DX, 648, 648FX, 649, 655FX, 655TX, 656, 662, 735, 756, 761GX, 760, 760GX, 755, 755FX, 741, 741GX, 671/FX/DX/MX ;

AMD® AM-751, AM-761, AM-762 (760MP) ;.

Under the MEMORY tab, it displays the type of ram i.e.SD, DDR, DDR2, DDR3; its Size, Channel i.e. whether running in single channel or dual channel mode. RAM timings are also mentioned which are useful mainly to Overclockers.

The SPD tab shows all the information related to the RAM. There is a drop down button for selecting the ram slot alongside which is mentioned the type of ram. Then there is Module size, Bandwidth of RAM, Manufacturer, Serial Number, Manufacturing Date and RAM timings.

The last tab is the ABOUT tab which tells about the version of CPU-Z, Operating System used and DirectX version. Besides one can make a dump of all the information shown in CPU-Z as a text file, html file or a validation file.

There are also special hot keys available:

F5 key saves a screenshot as a bmp file in the CPU-Z directory.

F6 key copies the current page in the clipboard.

F7 key saves the validation cvf file in the current directory.

Besides this the software also comes along with an executable called Latency. Launch the application in order to see the cache latency computation.

Overall, I software is pretty good as it is a freeware, there is no need to install it, takes very little space on the hard disk, supports major devices on the market and is easy to use. And u can run it from a usb drive as well.
