I've been reading about people having good success overclocking their Matrox M3D PowerVR PCX2 due to its standard crystal and built-in clock adjustment in the AV7-05 PLL Frequency Generator. The issue I'm having is that I want to overclock a card using Videologic's reference design which has a quartz crystal clocked at 66Mhz with no PLL chip.
I found information about this specific clock chip from the manufacturer as well as the datasheet.
I also found what appears to be a drop-in replacement 80 Mhz crystal.
Does anyone have any previous experience modifying this particular card? I'm also interested in trying other frequencies if there are other compatible crystals available.
This board will also accept a larger crystal if necessary without the need for additional modifications.
Here is an Matrox M3D for reference for anyone who wants to see how these boards differ.
Here the source I used for my research for anyone looking for modify their Matrox M3D:
