The G4 that we run on was a MPC 7410, which is one of the modules we have here for the XE but not the one that is going to be on the final version. I wasn't sure how high this one goes, so we left it at 400 MHz to be sure the CPU's not fried
I would have at least tried to set it to 1GHz just for giggles. Put a big fat fan on top.....Then again, just before a show, that probably would not have been a good idea.
Any word if it will use the standard Mac CPU modules for the G4's?
