Yea but those were 45nm, now we're talking 32nm chips though, I've run 1.53v 24/7 on a E6750 and 1.43 ~ 1.45v 24/7 on my i7-860 but 1.4 ~ 1.45v seems quite a lot for 32nm chips, I'd still probably use at least up to 1.4v on SB or possibly a bit more depending on how good/bad the sample is but wouldn't hurt to get more info from an Intel guy itself. :p
