    I noted that my 2.80Ghz (under Windows 7 64bit) gets "only" 2.92Ghz in Turbo Mode instead of what should be (3.06Ghz, in agree with apple site and intel specs).

    I know that the Turbo feature is influenced by the CPU temperature, but mine are really good.

    Any other experience? What's your max turbo frequency?

    Turbo boost is a con, you never, ever get one core loaded and the others 'offine' to get the turbo boost to 3.06Ghz for your 2.8ghz Xeon.

    My 2.66 only goes to 2.8 and I only ever got it to go to 2.93 was to disable all but the 1st core in Windows 7 using the bootconfig .:rolleyes:

    The upside is that your 2.8 will always be at 2.93ghz with all 4 cores loaded.

    Personally I think turbo-boost is a waste of time.

    before the mac pro I had a custom PC with a core i5 750 (2.66GHz with Max Turbo Freq. at 3.20Ghz).

    in the same conditions as I tested the mac pro, the i5 750 gets up to 3.22Ghz, as expected.

    anyway turbo is not a waste of time, but it does not change my life, it was just curiosity
