The developers of the Setfsb-tool agreed to implement their support for the Mac Pro Boards. They ran into some issues and this is why I NEED YOUR HELP! It would be very great because then EVERYBODY could overclock their Mac Pro´s under Vista 64bit which is not possible at the moment with any other tool, including Systool!! I need someone to run Systool on a first generation Mac Pro (newer generation Mac Pro is also ok, but 1st generation-one is preferable) under Vista 32bit NOT XP and then run setfsb found HERE. The steps one by one: 1. Set FSB to over 350 with the utility systool. 2. start SetFSB. 3. select the clock generator to ICS932S401EGLF. 4. click "Diagnosis" button. 5. click "Get FSB" button. 6. click "Capture" button. 7. PLEASE post the "Diagnosis" screenshot of the /setfsb2_1_94_0/capture folder I really hope someone can do this! Thanks a lot and greets form Switzerland" I got Vista 64-bit. Maybe got Vista 32-bit here and and would help ?
