I work in the PC repair business. If you run your AT at 10 or 12 MHz for
six months and THEN start having problems, don't send me the board and
tell me to ``FIX'' it so it works at the high speed again. I've seen
my share of 80286's that failed THERMALLY due to increased clock speed,
and also systems where the RAM or delay line for the RAM was too slow
for the ``new improved'' processing speed. Remember that all the components
in your computer work together , most at a speed determined by the crystal
you're changing. All you are doing is ``reving the engine higher'' without
changing the components that are designed to run slower. What happens when
you drive your car above the red line? That's what you're doing with your
computer, and while a safety margin is built in by most manufacturers, it
is not impossible to permanently damage components due to driving the
system too hard. 

Please, don't play garage computer engineer and expect a reliable system.
Weekend hot-rodders are continually fixing their cars. So are weekend
hot-clockers.


             I doubt any of these opinions are those of my employer.
                   I don't agree with ANYTHING they say.
