Ok here it is:
1) The mediator 4000DI busboard is in my hones opinion to close to the indivision aga.
2) running with an open case, meaning no airflow
I did not have a fan small enough to blow air in the two holes of the indivision aga, creating in and out flow.
But I glued a fan as close as possible creating airflow between the busboard and the aga, stressed aga with 64 colors workbench a bit, running one hour, and the machine reboots with a display image!

So the error is not reproducable, meaning probably fixed.:nod:

I cannot feal any heat on the aga card anymore so.
My personal idea is that getting an 060, putting the colors higher, running highfx is a little to much work without proper cooling.
