- I would say that this is a dangerout thing to do unless the motherboard
- manufacturer specifically says this is possible. If the board originally
- has a 33Mhz processor then the other chips on the board were selected
- to work at 33Mhz also. If you increase the speed to 50 Mhz you are
- violating the specs for other parts on the board.
-
- The board might work most of the time with a 50Mhz clock, but you are
- taking chances, and it could crash on you at any time.
