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.

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.
