Got this neat built by ATI card, cus its was cheap :rolleyes: But now i see my mistake, and find that nowhere on the web is a way to voltmod this neat card. Any help would be appreciated, and including a pic with partnumbers of the 2 most likely candidates for GPUvolt regulators. the top left one is above writing, and lower one below writing. It's hard to see writing, but it's an ISL 6539CA chip.

Again any help is appreciated.

Did you see this?

That's a very different looking layout for sure. Maybe a bigger picture would help, I can't really see much on this one;)

My one idea was wrong after looking this over. I posted over @ XS so maybe one of the guru's over there will have some idea(s) about this.

Have you tried checking the resistence on the various post of each IC? If you do you might locate the Posts that you need to solder to. I ussualy check this to make sure the voltmod will work with what i'm V-modding. The restistence between the two posts should be roughly the same as the max resistence your Pot you wan't to use. Resistence can be checked with the video card out of the computer.
