What is you render resolution and camera FOV?

This is just a guess, but it looks as if 1 GPU causes issues. Could try one GPU only and then test each of the 4 GPUs?

thanks for reply
karba : just a 2500x1600 pixel render, but these dots appear during a long cook (16000 samples), not at the beginning.
abstrax : yes, I was thinking about this,....

Hi there,
I never got that exact kind of problem, but have you tried playing with the RayEpsilon value?
(in the Kernel menu)
Cheers,
