I have found the following when overclocking...

When AMD states a CPU speed, they generally mean it... (i.e. a 350 is a 350
and will never be anything more.)

When Intel states a CPU it is the slowest speed for which it passed some
rigerous QC test.  Those that pass at 400 become 400's, those that don't
become 300's, (or so they say, the market has somewhat dictated the lower
end speeds, and therefore some are just labeled that for resale, especially
the Celerons.)

Most overclocking is done by changing the bus speeds.  While you might push
a 300 AMD to 350 by fooling with bus speed and multipliers the most you may
push it probably 50mhz.  On the other hand the Celeron 300 an easily be
pushed to 450, (while the 333 can only be pushed to 416 because of
multiplier lock, 5 x 85bus.)

The secret is in the motherboard.  Those that are "jumperless" and let you
fool with bus speed, multiplier and voltages are the best to use, at least
during the initial phases.  As stated before you have to find the right
combination of the three settings to end up with a stable situation.

The best overclocking value is the Intel Celeron 300a, ($65) and the Abit
AH6 MB, ($110) which can be easily overclocked to 450.  While not a Pentium
II system some say the 128k cache at full speed is better than the 512 of
the Pentium II at 1/2 speed.  Even if you fry it you can buy 5 more and
still be cheaper than a full Pentium II CPU!
