Last thing I knew the Unlocked Multiplier feature was reserved solely for the Core i7 965 XE and 975 XE. However, Anandtech and Wikipedia both say that every i7 processor, including the 920, features an unlocked multiplier. Is this true, or is it reserved only for the Extreme Editions like I originally thought?
