need g400 PINS help

[thop]

so after 3 years or so i finally decided to o/c my g400 via PINS (for some q3a action)
i've searched the forum for the past hour, and checked out the matroX files, but i still didn't find out how to change the memory clock, and if i can change the core and RAMDAC independently.

here's my PINS file:

help

[Gohan]

Why don't you use PowerStrip?

[thop]

one more app in my systray. also i want to do it once, and forget about it then

I'll check the archives for a G400max pins file to compare to.

Yo look at this here you can find it all just read it and read is carfully and one good advise make a rescue boot disk firt is somthing go's wrong you can always use the resque boot disk

hmm still cant figure it out.

I'm not sure if you can do 140/180, more like 140/186 or 136/181 (182 ?).
I think it has a (3/4) core/memory ratio and what you can change is the core clock (for 2D and 3D) and it applyes the clock to memory based on the 3/4 ratio.
Well, I don't really know much about it, someone with more knowledge can explain the mechanism to you.

Anyway, to do 136/181 (182 ?) you need to change locations:

65 1 136
66 1 68

75 1 136
76 1 68

and for 140/186:

65 1 140
66 1 70

75 1 140
76 1 70

Make sure you backup your original pins and also get Matrox's Restore Bios utility, in case there are problems.

Actually that 3/4 ratio and that it adjusts memory autoatically according to the CORE clock was the info i was looking for. thanks a lot admiral

[thop]

wooohooo it worked also made the 75Hz DOS thing.

[Admiral]

How far did you push it ?
