Devices attached to the PCI bus are much less over clocking friendly then either memory or a CPU. When you overclock a processor using the system clock your processor speed is determined in the same way as one would for finding normal clock speed: processor multiplier x system clock = processor speed.

CPU speed is how fast the actual processor clicks, or the amount of bits it can push through per second. The System clock is equivalent to the bus speed, which used to be either 100Mhz or 133Mhz. Nowadays the System clock might be 266, 400, 533, 800....

Whereas an Intel 80286 microprocessor requires 20 cycles to multiply two numbers, an Intel 80486 or later processor can perform the same calculation in a single clock tick. ... (Note that clock tick here refers to the system's clock, which runs at 66 MHz for all PCs.) These newer processors, therefore, would be 20 times...

SysClk and SysClk* are used to drive an on-chip phase-locked loop (PLL), which multiplies the system clock to create an internal processor clock, PClk.

The processor further includes a second system time clock providing second time values in response to being periodically incremented by the CPU.

18. The control method of the multiprocessor system according to claim 10, wherein said step of controlling the frequency of the clock being input to said first processor includes the steps of; counting the processing time of said first processor, counting the processing time of said second processor, and;

The computer system includes transitioning a processor (CPU) into a low performance mode using a clock generator that provides different clock frequencies, a high performance clock frequency and a low performance clock frequency depending on whether battery or AC power is used.

System Clock Tutorial & Circuits - Microprocessor Systesms Tutorials - Electronic Hobby Projects - The clock is a square wave generator whose frequency is controlled by a crystal. In a typical control system it oscillates at 1MHz (1 million times a second) and controls the speed at which the system operates.
