what is overclock?
Overclock that personally had definition that is overspeed the computer above standard speed that was determined. For example Intel Core 2 Duo 6300 with clockspeed 1.866 GHz was overspeed to clock 3 GHz.
Overclock indeed became special preoccupation for the extreme users of the computer. With the minimal system, the user tried to search, what part in system that still could be maximised, with the addition of the cost and the peripheral as minimal as possible.
