This confirms what was already suspected. These chips die quickely on high vcore, at least quicker than 65nm chips. Again, loadline calibration and similar tools to bypass vdroop might give you a confortable feeling of security setting vcore to 1.4v, while, in real world, it hits 1.5v 1000x/sec without you know (overshoot)
Intel should have be more clear, but hey, no one would buy a 45nm if we can't OC to death :-)
