Re: what exactly CAN you overclock?

Discussion in 'Overclocking' started by Andy Cunningham, Jul 11, 2003.

  1. In theory, any component with a 'clock' can be overclocked. A 'clock' in
    this sense is an electrical pulse used to coordinate activities within the
    chip. The clock is produced by a clock generator. For many parts of the
    system, the clock is controlled by the motherboard via the FSB. The CPU and
    RAM clocks are arrived at from a set multiplier / divider of that frequency.
    Many motherboards allow changing the FSB speed, which in turn changes the
    CPU and RAM speeds. Most motherboards also allow changing the FSB/RAM
    divisor. Many new motherboards implement a separate clock controlling the
    PCI and AGP buses, settable independantly of the FSB clock - older
    motherboards set these buses by further divisors based on the FSB speed.
    Graphics cards also use separate clocks for their GPU and memory. These are
    usually settable through driver functions, accessible through various
    tweaking utilities.
