I was reading on here about overclocking & voltages and heard if you increase the Vcore, the process of electromigration speeds up? Can't remember if that's exactly what it was called, pretty sure it was, can anyone enlighten me on this? Many thanks X
Electromigration?

I believe that's correct. For example, I'm running my 65nm processor at 1.53-55V 24 hours a day and apparently it's gradually killing my processor regardless of the temperatures. I can probably agree that I'm killing it earlier than intended but if I keep it cool enough it won't speed up the process too much.
Also, electromigration happens over a long time unless the voltage amount is extremly excessive, such as popping 1.8V through a processor.

Unless the voltages are increased significantly the electromigration process reduces the ~10 year lifespan of the CPU to ~7 years so it's nothing to worry about, as most people will have upgraded by then.
You may want to look up 'Sudden Northwood Death Syndrome'.
Back when the P4 Northwoods were popular, a lot of people were heavily over-volting their CPUs which resulted in a large number of Northwood P4s failing after a few months of use.

Wikipedia have a section unfortunatley neither that informaiton nor anyone else can reasonably predict how much extra damage an over volt will do. But if you dont need the extra volts dont apply them.
Overclocking increases damage too as more current is used but at least the designer would have had some margin in mind for launcihng faster processors.
CPU's do fail (see ebay) but their design life is high and in most home applications they will be replaced before they fail.
I suppose one day someone will launch cheap cpu's with short use by dates.
