Core i7 - Is High VDimm really a Problem

Anandtech posted an interesting article on the subject that confirms what some people have read on here.

It's here http://www.anandtech.com/memory/showdoc.aspx?i=3426

Put simply, if you go crazy with VDimm, let’s say around 2.0V~2.2V without additional tuning, then expect to greatly reduce the processor lifespan to a few weeks or maybe days.

So sounds like you have to be careful with that expensive memory

Gibbo was saying he was running his at 2.1v with no problems, though looks like it will go pop very soon.

Yeah thats what interested me. We all know Gibbo is a power freak though, just look at his cars!

Its a problem but not unexpected generally with voltages at this level of electronics - usually 10% is perfectly safe, 15% minor risk, 20% moderate risk and anything over that dramatically shortens lifespan - so I don't know why people act so suprised... granted its a bit of a hinderance with RAM performance.
