    Hi all,
    Sorry if that question was answered earlier, but why is the base Octo core on 1066 memory whereas it is a Westmear architecture ?

    I thought the quad cores were 1066 because they still are Nehalem.

    Thanks for clarification on that.

    The processors don't support 1333MHz memory. Nehalem and Westmere higher end processors (QPI of 6.4 GT/s and costing $900+) support 1333MHz memory. Apple just disabled it on the 09 models.

    Yes, ok that I understood, but the 6 and 12 cores support that memory and they are supposed to be the same generation aren't they ?
    Did intel make processors in the same generation ( Westmere) that support different memory speed ?

    Or are the octo westmere and 6 - 12 not really the same architecture ?

    They just have a different memory speed. Memory speed doesn't really have anything to do with architecture.

    Ok, thanks.
    From what I read, going from 1066 to 1333 does not improve performance tremandously anyway. SO I suppose it does not matter so much
