Computer speed check tools are used for checking the clock speed of the CPU in your computer. You can download either the shareware or the freeware versions of the software and check various parameters concerning the speed of your computer system. You could also use one of several web-based computer speed check tools available on the Internet. There are two kinds of speed checks which are usually done on PCs; one which checks the CPU and other related speed elements in your computer, and the second one is the bandwidth speed of your ISP as related to your computer.

Computer speed check tools measure the actual performance speed of the CPU in your computer. Typical computer speed check software would indicate various aspects of your CPU speed parameters, such as, whether the CPU in your PC is over-clocked with your CPU clock speed running at a higher rate than specified. It would also indicate if the CPU is running faster than what it is rated, and whether the CPU is operating in its usual normal range.

Generally, the speed at which your CPU runs is available in your computer, especially that of Pentium 4 or later versions. Your computer should be performing at this speed or below the speed as specified by the manufacturer. A detailed description of the three levels of caches, as supported by the CPU in your PC, is also made available by the computer speed check tool. The larger the cache size, the computer becomes that much faster. Some of the speed check tools feature memory speed checks which provide information about the speed at which your data transfers take place between the CPU and the memory. This information is usually given in megabytes per second. The speed of data transfer is measured by execution of large memory to memory transfer. The transfer rate determines how fast your computer is.

Your speed check software not only checks the speed of the CPU in your computer, but the features allow checking of every speed component in your computer system, your network speed, and the speed at which your computer accesses the Internet. Some of the professional computer speed check software provides a control panel by which you can change the settings of the parameters for measuring the different speed levels of the related components such as, CPU clock speed, memory speed, etc. Results of these measurements are made available in a separate graphical screen.

By making changes in the BIOS settings, the clock speed of the CPU in your PC can be adjusted. If you find the speed of your computer system is falling, there could be various reasons for its lowered performance. One could be that the CPU in your PC is not operating to its specified speed, or there could be something wrong with your data transfer rates. Computer speed check utilities may be used to find out various speed elements in your computer. The analysis done by the software can help you determine which speed component is affecting the performance of your computer.

The type of CPU in your computer is automatically detected by the BIOS in your system. The BIOS also sets the clock speed of the CPU which can be adjusted by setting the multiplier factor in the BIOS. The overall functioning of your computer depends on the CPU clock speed, the multiplier factor, and the bus speed of your PC. The bus timings in your PC determine the speed at which data is transferred. If the rate at which the data is transported gets to be low, the performance of your computer degrades accordingly. Computer speed check utilities offer several features, and you can choose the one which is right for you. There are basic tools which just check the CPU speed, others provide detailed analysis of the speed related components in your PC.

The clock speed of your CPU could be set from your BIOS. This is done basically by setting the multiplier, which determines the overall CPU clock speed. Take the example of a processor having a speed of 550 MHz with a front side bus speed of 100 MHz. This would mean that the multiplier has been set to 5.5 times the speed of the front side bus, which in effect makes the processor work at 550 MHz. Before you set the CPU speed through your BIOS, you Sneed to find out the various parameter values that are governing the speed factor in your PC. Computer speed check software provides you with all the information that you require for setting the CPU speed correctly in your PC.
