Me and a friend was able to remove the brand/card model restriction, and the voltage limit. If you guys allow a patch to be posted, I will post it. (I won't post the original program, just a patcher file) However, I was unable to test, as I don't have an NVIDIA card anymore.
Here's a screenshot of it running with the patch
By "limit removed", I mean set the max to 2.00v I can make it higher, but I don't think that's necessary.
