You know that overclocking the CPU drastically reduces its life span and automatically voids the warantee.
I take you off Ignore, and you post this crap...
Okay, look up the QX (Intel) and Black Edition (AMD) range. These have unlocked multipliers, for the sole
purpose of Overclocking. There is no other logical purpose to having unlocked multipliers.
If you want to get into the "Electro Migration" argument, I wouldn't advise it.
As has been stated, if the useful life of the CPU is now, ooohhh.... 10 years say, instead of 50-100, who cares? I guarantee you I will not be running it in 10 years, and I pity the person who is running it for anything other than Nostalgia or Collectors Value.
FWIW, I am running an AMD 6400 Black Edition now, and I have in the next room, a perfectly functioning AMD 386/40 that was ran at 56MHZ (IIRC, this was a while ago to say the least) for a few years. Crystal swapping was good, if somewhat unpredictable. There is also an XP1700 there as well, that, unless it's been beaten recently, holds the Euro aircooled record for that chip at over 2.8Ghz. Funnily enough, despite running at nearly double it's official rate, and having a rather large amount of volts shoved up it's Vcc pins, it still works perfectly.
