It is still a gamble according to what you say. > >-Matt I'm just saying you will get 2.3GHz out of an AIUHB 0242 or newer. That is a definite. Now, getting higher is up to the chip. It looks like the average is around 2.4ghz or so.. but if you want an absolute guaranteed 2.3ghz then you can't go wrong with the AIUHB 0242 through present (latest I've seen is 0304). Pretty good deal for $97, and if you want a definite 2GHz a JIUHB (any date) is your chip, and again.. $56 makes it a steal. :)
