I will admit some trepidation at the thought of overclocking my MDD's bus. However, looking at the specs across the board of MDDs, mine is a second generation with FW800. All the first gen were running a 133MHz bus like mine, all the others run 1.67MHz. It looks to me like my machine is the first example of Apple's tendency to deliberately cripple the base model in every given range of PowerMacs (Think about the G5s with only four RAM slots). So based on this I figure there is a good chance that my board is the same as the other rev2 MDDs, and quite likely, the chip is the same too. Just downclocked by Apple, since they couldn't get the top of the range ones to run any quicker.....
I guess I could check the part numbers on some logic boards.
