Why not use 6.82 drivers then?

Because there are no additional tabs on the screen properties window. Only 6.23 driver has additional tabs - Information, Options, DualHead, Monitor Settings, Color where you can set a custom resolution on Monitor Settings tab:

Success! I've been able to modify the pins and the new frequency is now 124/155! I did two tries, the first one I modified just the pin 56 and 92. It gave the new clock in dos but not in windows, then I modified every 72 in the file to 78, it gave the higher clock in both environment. Apparently there are differeent clocks for different modes. The performance are faster, it doesn't suffer the drawback of powerstrip overclock. I'm going to push it further, if anything goes wrong I will be able to revert to the old pins.

As attachment the modified pins.

The attachment G450OC.TXT is no longer available

78 = 124/155
80= 127/159
83=133/166
87=139/173
88=140/176
89=143/179
93=149/186

I can say that the card doesn't support the 200 mhz on memory, it shows artifacts after some seconds.

I've been expierencing the same behavior with PowerStrip when trying to OC my 115.2/144MHz G450 PCI card and I found this post.
Well, I can't figure out how to use this text to overclock it. Could you please explain a bit more?
Also, my card has bios 1.7b3, are there any gains/disadvantages if I upgrade it to 2.1?

That's stuff I did 2 years ago so my memory can betray me.
With progbios there is a switch to use just to modify the pins, since in matrox cards they can be flashed separately.

Thank you for the instant reply! I'll search it further 😀

You are welcome, unlucky I don't have that pc working at the moment so I can't help you much but I'm sure you can flash that txt file with the right switch to have the overclocked frequencies and the bios you already have.
I didn't notice any difference between a version of the bios and another, unlucky I doubt there is a public changelog.
I also have another glimpse but it could be for the g550, which came with 6ns and 5.5 ns memories, the latter were able to achieve obviously a higher overlcock.
