When I edit the 3d clocks _below_ the lowest possible clocks in CCC, my computer crashes when entering windows. This can be fixed by not loading CCC on startup. Now I was wondering if it was possible to be able to boot into windows successfully at ultra low 3d clocks, while still loading CCC? Is it possible by editing the registry, or will this have to be done in the bios with signatures as well, just as the upper-limit? Thanks for all the help! Ps. As for all the people wondering why I'd like to be able to do this: I am trying to figure out the multi-monitor flickering problem and this might help us get a fix out for this problem. Edit: This probably has to do with the fact the signature still states the default clocks are 850core/1200mem. Is it possible to edit these values as well? Or to make the lower-limit lower than they currently are in CCC (600/900)?
