Maybe, but I've never hit the CUDA button after installing ram, or any PCI card, and everything shows up correctly. (7600/132, 8600/200, 733 QS and dual 867 MDD) Maybe I've just been lucky. I did push the CUDA button when I installed a G4/450 card in my 7600/132. Is there some reason I should have?
