Voltage Question

I have an E5200 with a VID of 1.225V that I've overclocked to 4.0Ghz at 1.5V (CPU-Z reports 1.488V). Load temps never go above 60C.

So, the question is - how much does increasing the voltage to this amount affect the lifespan of the CPU? Is this something you really need to worry about?
 
if you have good cooling, youll replace it before it dies. its going to effect the lifespan, maybe take 1 year off the expected 10 years.
 
Thanks, that's what I thought. When researching the subject I found everything from "Don't worry about it" to "OMG your chip is going to fry!".

This system just has to last long enough until the mainstream i7 stuff comes along, then it'll most likely go back to stock and become a NAS/server box. That doesn't need much, my old A64 3200+ will handle those duties until then.
 
1.5V on a 45nm C2D is way more than I would say is safe. Consider that Intel rates the absolute maximum voltage for that CPU at 1.45V, and it isn't guaranteed to operate at anything above that level. Even if you aren't bothered about killing the chip, I would still back down to 1.45V or less, if only just to make it more likely that it'll be able to maintain the same overclock until you end up replacing it. 4GHz should be doable at around 1.4V anyway, if you tweak your other voltages right.
