who has tried over clocking the at89c51 in KEIL C? how fast can it go? 10% 20% 100%? post your results.
well a bit roundabout answer is "there has been several threads over the years "why does my chip fail when I overclock"

Overclocking is similar to running with badly stabilized supply voltages. It might go well. But don't be surprised if it locks up or you get a corrupted result computed.

not only that, but "It might go well" and then days later when some coincidence happens (e.g. two ISRs firing at the same time) some "unexplained bug" may show up.
Overclocking obviously means that what works in the winter can fail in the summer because of a higher ambient temperature. And it matters if the equipment is near a window and the sun is shining on the device or if it is in shadow.
