Thanks Scott and Ross!
I have 23950 atoms and it's happening at random places given the same input
as you wrote, Scott.
The cards (both of them) produce the mentioned error from the first use ...
I have tried the 319.60, 331.20, 331.38 drivers. Now, I will try the 331.49
driver, and the test tool from Ross, than I will write again.
All the best,
Robert
