Core i7 Overclocking by Batch #

[Osterman]

I habe been offered 2 different kind of batch.
One kind is 3849B wich is known that some can to 5ghz minimu with dice. I think the complete batch is 3849B028.
And the other batch is a 3845A wich was tested and it can do 4.2 with 1.25vcore

Well, does someone has one of those so I can hear at least one more opinion.

Thanks in advance.
