Afterburner crashes Windows after 7th GPU on startup

[dragonmike]

I set all my o/c settings in Afterburner and set it to apply on startup.
Unfortunately, it crashes/freezes the PC upon applying the o/c on the last, 7th card...  Every time

Any idea why it's doing this and what I could do to solve? I'd really love to use AB rather than specifying values in Claymore...
