Well, there's an important point to be learned here... this may be a
stereotype I'm entertaining, but I generally would consider overclockers to
be people who leave their computers on for long periods of time, and are
very sensitive to what works and doesn't work. On the other hand, there
are *many* people I know who don't know how to overclock, and have systems
that are running at the rated speed but have *frequent crashes* due to
other system problems that they are not aware of. Case in point: my
computer used to be unstable; had I not been experimenting with
overclocking, and spending time trying to figure out why it was crashing, I
probably would have never found the bad ram chip I had, which was causing
crashes at *any speed*.
Overall what I'm saying is this: With the success that many have, it's
clear that most chips *can* be overclocked. Yes, these chips probably do,
as a result have a "1-in-a-trillion" chance of having errors.
Unfortunately, when a survey of computers is taken, I'd bet that 1 in every
50 computers running at rated speed has a worse problem. A good analogy
may be this: How many race cars burn oil? Conversely, when you're driving
on the road with non-race car drivers, how many of them have oil leaks?
Well, that's enough babbling for now. <g>
