A On older computers such as the 386 and 486, the processor often ran at the same speed (that is, had the same clock speed) as the motherboard. The 486DX2 processors introduced clock-doubling technology that allowed the processor to run at twice the speed of the motherboard. With your 486DX2-66s, the processor has a clock speed of 66MHz while the motherboard runs at 33MHz. With Pentium computers, the speed of the processor varies even more from that of the motherboard. However, the settings for the processor and motherboard clock speeds are on the motherboard. This places a limit on how fast a processor you can put in a Pentium motherboard. With the HyperRace processors, the clock multiplying takes place internally on the processor. These processors were specifically designed to add extra life to 486 computers.
