Does anyone know if it's possible to overclock the bus speed on a Digital Audio? I've found places online where folks talk about overclocking other G4 models but haven't found anything specific to the DA. If anyone knows, I would be interested in some concrete/proven step-by-step instructions. I've done just about everything else that can be done upgrade-wise to my machine, but some faster overall performance would be great. BTW just want to say up front in case anyone wants to know if I've upgraded the GPU, the CPU (and overclocked it), put in SSD for boot drive and maxed out the RAM, the answer to all of those questions is yes.
