FSB speed value can be seen in CPU-Z RRS feed

  • General discussion

  • Hello

    My name is jiyoon Park, I’m student studying intel CPU architecture.

    I have been know ‘CPU-Z’ program can showing CPU specification in current CPU.

    using CPU-Z, we can see Core Speed, Multiplier, Bus Speed..

    I think there is register that store Core Speed value, Multiplier value or Bus Speed value like MSR(Model Specific Register).

    I found MSR_FSB_FREQ that indicate scaleable bus clock speed for processor in Intel Core 2 family.

    But Intel microarchitcture code name nehalem including Intel Core i7 and i5 processor family, can’t know bus clock speed…. can’t found MSR_FSB_FREQ….

    Is there any register that I can get FSB? Or how can I calculate FSB Bus speed?

    Thank you for reading, and my poor expression, please approve it.
