I would think the last thing you would want to try is to OC an 040 CPU. They run so damn hot in the first place. You would need some serious airflow to keep it cool, and burning it and/or the accelerator would suck. I would not recomend it at all. You would be better off just getting an 060 accelerator. I'll bet in the next few months if OS4 comes out people will be selling off there classic Amiga to get an Amiga One like crazy if all is working as announced.
