Re: i5 2500k OC help!!
I've an i5-2500k too.
When researching, I came accross an article (I think it was Bittech) that said intel had directly informed them that 1.5 volts can be handled by those CPU's as long as the temps are in check. I had to used 1.45V to get 4.9GHz outta the thing, but, when using manual voltage settings I couldn't get the sleep states to function correctly - and I like the sleep function of my PC.
Luckily, for me, I run prime stable on stock voltages at 4.5GHz.
I, personally, would up the voltage to 1.392V for your overclock and not worry about it. Sure, there's the possibility that the life of the CPU might shorten, but I think this is more heresay than fact - as I've never seen it happen, and every machine I own has been overclocked and, with the exception of my current build, over volted. If the temps are fine, the CPU will last as long as your ever going to need it.
Go for it! Live on the edge. Infact, take that heatsink off and start cooking eggs :P
(P.S. Don't take that heatsink off! Suppose, thermal throttling would protect it anyway....)
