I just came across this article on Anandtech, linked from their Ivy Bridge review:

It's very interesting. While upping both the voltage and the clock speeds have rapid and averse affects on the temps of the chip... they managed to get a significant, stable overclock at 0.90 volts! Which suggests to me that if we go about it the right way, we can actually do fairly well at overclocking IB. Probably not as insanely awesome as SB, but still.
