  • Matrox G400 32mb SH

    System Pentium Celeron 400 mhz 66mhz bus
    When i start the system in plain dos 6.22
    from a floppy en after that i run G4set
    it gives the valuas stated on this forum
    sclk 252
    G:d 1/2
    G:f 126
    M:d 2/3
    M:f 168
    W:d 1/2
    W:f 126

    So that is what it should be or not???

    When i change the FSB from 66 to 75
    Celeron on 450 mhz

    same procedure

    The G4set readings are

    sclk 165.857
    G:d 1/2
    G:f 82
    M:d 1/1
    M:f 165
    W:d 1/2
    W:f 82

    Twice the system is booting from a floppy
    generated bij sys a:
    copy G3set to a:

    that's all

    So no blame at the address of Pstrip.

    After seen this weard fonomena
    i cheanged the G400 bios back to 1.1 from the
    Cd.

    All the same.

    When the FSB is set to 75 MHZ i can change
    the setting back to what i see with 66 mzh
    The card will stick to that even after rebooting 10 times or more.


    Bottum line Whe have to Thank Matrox
    for a self regluating bios.
    Tho if you overclock the fsb above 66 mhz
    read the values before changing the fsb.
    After the change patch the bios with G4set
    to the values with 66 mhz.

    Succes Rob.
