I have a P4 775 stock at 3.0ghz i managed to oc it 3.527ghz it runs stable but i was wondering of the long term effects on the processor itself i have read a few things about the down side to ocing but i was looking for a little more info then i found any one who could help i wold appreciate it.

Could be bad if you dont have proper cooling

i posted a message about my cooling systems about a week ago i am running about 47c on the cpu and 28c on the system i was wondering about the life of the cpu and if it was good to always run my cpu oc i placed a couple of custom high rpm exhaust fans on my case there is more than enough cool air flowing through my case. Is the life of my processor shorter if i run it oc or will it last longer just leaving it alone also how long does a cpu last???? Thanks a ton

Does it shorten the life? Yes.

Will it shorten it to the point it will die before it's useful life is up? Almost certainly not.

Ie, it will now last 10 years instead of 12 years. Look at the CPU's of 10 years ago, and tell me - would you have any use for a Pentium 60 or 75MHz? I'd venture no.

Just keep it cool like you're doing, and you'll be fine.

If those 47°C are for running at 100% cpu
usage it a good low temperature and I don't
expect any problems.

If it's mesured with the cpu doing almost
nothing it will get hotter if you really
use it and I guess in that case it will
become quite hot.

Better check that because above 60°C you
shouldn't really go.

BTW:
I have my Athlon TBird now for about 5,5
years and from the first day it was clocked
to 10x133MHz instead of the original
12x100MHz and it's about the maximum it
will do. I got it a few MHz higher but the
benchmark results dropped so I got back to
the above setting. It alwasy ran quite hot
and stopped working at around 63°C so I had
to clock in down nearly every summer on hot
days until I found a unique way of cooling
it with self build air channel last year.
It's still working without any problems
after all that thim and now my nephew is
playing on it if he's visiting becasue I
upgrade to an Athlon64 at the start of the
year so that Athlon and board replaced the
750@1000MHz platform that was my nephews
game PC before!

Whether OC is a good thing depends on what you are doing with your computer.
My 1.8 gigahertz Athlon 2500 runs flawlessly with most programs while OCd to 2.2 gigahertz with most programs. But the software for my scanner won't work with the machine is OCd. Since I do a lot of scanning I had to drop back to standard settings.
