All right! But that answer  leads me to other questions.
There are motherboards that allows you manually to select the system bus,
cpu clock, voltage, etc.
I´ve heard many times about multiplier locking in Intel CPUs.
So. The CPU clock is internally genarate?, or it comes to a pin and then is
multiplied inside the CPU?
Even when the CPU runs at the right frequency, if the mobo detects a PIII
coppermine, that works at 1.65 volts, is the celeron being overloaded with
0.15 volts more (think it should run at 1.5 volts)
