Wrong....Heat just accelerates electromigration rate.
Yea I had heard that electromigration kills the CPU, and it is accelerated by increased voltages and increased heat (which unfortunately usually go hand in hand). So theory would tell you that the part's life is decreased on any overclock, but by how much? That's what I'm trying to gage based on the experiences of OCN members how much of an effect it has.
Unfortunately I doubt any real scientific data can be collected, as we'd need to take many processors at stock and see how long they lasted on average under load, then take more of the same processors, overclock them and submit them to the same load and compare the lifetimes. No one has that kinda cash, time or probably even interest in the results haha, so I'm settling for answers like "my rig has been overclocked for years with no problems"
I'm more interested in this based on recommendations I'm making to friends and family. I'd feel guilty if I promised a long lasting overclocked machine only to have it die in 2-3 years. Most of us are gamers and replace our systems every 2-3 years but these old folks like their's to last a long time and I want to make sure I'm not significantly contributing to the computer's early demise.
I personally have lost a motherboard in just 18 months (and only 6 months of overclocking), but I can't be certain it was the result of overclocking as it could have been random failure or related to my UPC that was acting up.
