I'm the author of nvclock, nv30 based boards work different related to overclocking. Nvclock 0.7 will contain nv3x support but no overclocking yet since I don't have access to a nv3x based card
Hmm .. didn't read the second post ..
Did changing that make nvclock work on a FX5200?? Since I need a totally different algorithm for the other nv3x boards (FX5600/5800/5900). Did it see everything correctly at startup?
Please try to email me too, I'm not allways on this forum and I need more info.
