Thanks to Anton Nilsson at Nordic Hardware for sending over the Info:

In our review of the Intel Pentium 4 3.2 GHz Extreme Edition, we mentioned that it was an unlocked engineer copy. We surely hope that the 'real' P4 EEs will be unlocked as well, as this is a CPU for the enthusiast market. We do not have any information about regarding this, however, a piece of very interesting information about Intel's arch-rival AMD's enthusiast processor Athlon 64 FX and its multiplier is at hand.
