The Scope for
Improvement
The multiplication factor that the processor applies to the (external)
clock source to produce its internal clock can be compared to the
transmission in a car; increasing the transmission ratio allows the car to
go at higher speeds. Similarly, increasing the multiplication factor that
the processor applies to the clock source causes the processor to use a
faster internal clock, and so to operate more quickly.
The processor’s clock multiplication factor is determined by switches
on your PC’s system board. These switches set both the internal and
external clock speeds for the processor and must be set correctly for
the speed of processor installed in your PC.
