    Step 6 --> Finding the fourth MSF
    We repeat the same procedure.
    Analyzing current data (O/c analyzer exponents):



    Exponents n1,n2 are:



    Xm n2=0.927 > n1=0.908 that's why you see negative loss....
    This means that this CPU loves Vcore!
    But after a point n is expected to be slower and so on...

    Anyway let's run General CPU speed estimator:



    The Vcore4 was 1.510 Volts (1.500 in BIOS and +3.3% VID increase --> MSI settings)..
    O/c analyzer find frequency/FSB:



    BAN method now!
    MSF4 <= 2544 (cos of O/c analyzer find frequency/FSB)...
    2520 < MSF4 < 2570 MHz (cos of General CPU speed estimator --> note 2519 MHz is the smallest value almost 2520 = 10 X 252 MHz).
    Thus 2520 MHz < MSF4 < 2540 MHz.
    Reboot and 10 X 254 MHz --> system failed SuperPi 8M.
    Reboot and 10 X 253 MHz --> system failed SuperPi 8M.
    Reboot and 10 X 252 MHz --> system passed SuperPi 8M!
    Thus MSF4=2520 MHz and Vcore4=1.510 Volts.

    Note:
    The second area of General CPU speed estimator has the smallest C.C. of all but 2519 MHz is more near to 2520 MHz (the actual MSF4).
