  • Overclock Matrox G450 with by means of change of contents PINS 5.1. Help please!!!

    Dear Experts!
    Only you know structure PINS 5.1.
    I am engaged overclocking Matrox G450PCI.
    PINS 5.1 by mine videocard:

    ;MGA Bios Programming Utility v2.28.000d
    ;(C) Matrox Graphics Inc. (2001)
    ;
    Fill: 0 127 0xFF
    ;Matrox G450 PCI
    ;VGA Enabled - BIOS V2.0

    I have changed SClk with 288MHz on 376MHz.
    As a result of frequency: GClk=WClk=150MHz, MClk=188MHz.
    Memory frequency with factor 1/2,
    and GPU with factor 2/5 from frequency of the system generator.
    However PLL can form on the output of frequency and with
    other factors: 1/3 2/5 4/9 1/2 2/3 1.
    Prompt please where the factors PLL in PINS 5.1 are written down and what
    values correspond to all ruler of multipliers from 1/3 up to 1.
    Very much to you I shall be grateful.

    Roman.
