I actually never succeeded in harming a CPU by over clocking. With the P4
CPUs there is not much idea in over clocking, they are normally fast enough.
Back in the the "old days" there was a lot to gain. Big difference in
running a 486 at 25 MHz or 40 MHz.
Anyway, who cares if the lifetime of the CPU is reduced to 5 or 10 years,
never used the same CPU more than 2-3 years anyway.

Those who has been trying to over clock a CPU, will know that often it
is
possible to tweak extra MHz out of the CPU, after it has been working
several hours.

CPUs are made to work at one temperature range well. You can push
them, but any "burn in" is likely hurting it.

It seems the height of idiocy to take a $400 CPU/MB combo and
shorten its life by half to squeeze out 5-8% more speed.
