A processor is a commercial product. That’s why no one computer company produces only one kind of processors. They produce the so-called product line of processors. It is always built using the same technology and the same materials. The difference is set for ready product: “fast” processors are expensive and “slow” processors are cheap. This difference arises from the multiplying ratio of a bus frequency which formally cannot be changed. In some cases you may try to change it yourself. But if it cannot be changed, you can try to change the bus frequency.
Thus, if you have a processor of middle frequency and price, it can be easily overclocked to the speed of more expensive and “fast” models. The outdated models of processors can only be overclocked to 10-15%.
You can overclock your processor using BIOS or switches on your motherboard.
How to Increase Computer’s Productivity Using BIOS?
The higher the bus frequency and the bus multiplying ratio (multiplier), the higher clock frequency you will get. It is better to increase frequency from a multiplier – this influences only processor and does not affect the other elements. But in most cases this procedure is unavailable.
In most modern versions of BIOS all setup parameters for multiplier, bus frequency and voltages are listed under the heading “Frequency/Voltage Control” (CPU Frequency Control, Hardware Monitor Setup). In older versions of BIOS some parameters for monitoring the bus frequency can be found in “BIOS Futures Setup”.
