I've read conflicting reports on whether or not the non-extreme Bloomfield and Lynnfield will be locked, so as not to allow overclocking. Is it true that the $999 3.2Ghz edition is the only Nehalem incarnation able to be freely overclocked?
Anything you hear about this now one way or the other is just going to be an unsubstantiated rumor. Even if the lower end Nehalem's have locked multipliers they will still be able to be overclocked, but it will be more difficult. Remember, people have been overclocking AMD Athlons with locked multipliers for years.
