I agree with that, but for example you could speed up the Pentium 70Mhz
to 90 or even 120 by just raising the clock speed. They make all
70,90,120 to be the same speed, but they test them at 120 until they
meet their quota, then 90, and then the rest are 70s. Some 90s don't get
tested as 120, and still might work. and most 70s are never tested at
all, so they could be 90s or 120s.


It doesn't wear out the processor even if a test fails at a higher
speed, if it did they couldn't keep testing them at lower speeds.


There was a nice article in Dr. Dobbs about how to speed up your Pentium
70 or 90.
