Overclocking, techniques for increasing your computer's performance

Pushing other components

Any other element in the computer which works at a certain clock speed is capable of being stretched, including those at the motherboard frequency, which is responsible for sending data to the memories and PCI cards, and the graphics cards processors, for which there are specific programs. The hard part is finding out how to increase the speed of this element.

PCI DEVICES

The design of the PCI devices determines the work speed at 33 Mhz, half the frequency of many motherboards, since this value is obtained using a divider. So, when you increase the speed of the motherboard bus, the PCI bus also accelerates. As an example, with the boards that allow the bus to be put to 75 Mhz, you are stretching these devices at 38 Mhz, and if you put them to 83, the PCI bus will go to 42; in other words, the frequency will increase by 30%. It should be remembered that in more modern boards (from 100 to 133 Mhz), this frequency has to be divided by 3 and 4 respectively to get the bus frequency.

MEMORY

The memory works at the same speed as the bus on the motherboard, which means that by increasing this value you are also increasing the speed of data transfer between the memory and the system. It is a good idea to buy memory that can work at 133 Mhz so that you are not restricted when overclocking.

STRETCHING THE ISA BUS

To stretch the ISA bus, you just need to change some parameters in the BIOS. According to the specifications, the ISA bus works at 8 Mhz, and to get these 8 Mhz the board modifies the speed of the bus according to a dividing number to give 8 (or a similar number). This divider is usually indicated in the BIOS as clock divider, ISA clock divider or similar in the Integrated Peripherals section.

By decreasing the divider, you increase the speed of the bus, and any card connected to the ISA bus will go faster (SVGA cards, hard disk controllers, SCSI, network cards, etc.). However, this feature is tending to disappear in more modern boards.
