Just spotted this bit of Info over at OC Forums posted by c627627! For those of you that haven't heard, new Bartons, Thoroughbreds and Durons are factory multiplier locked, (not even wire tricks work with them.)

It's finally official: ""...we now have a policy to lock down the frequency of all the products so there?s one product that will continue to be open and it?s the FX product line." Henri Richard, AMD Senior Vice President of Worldwide Sales and Marketing
