Hello there,
trying to render in MAX with Iray GPU Support prove to be a
more complicated task. While Nvidia Mental ray does work,
Iray refuses to make use of the 4 Quadro 2000 cards installed.
They are not driving any displays and should be used for compute
only. The displays are attached to a AMD-W-7000. The control-
panel will not show unless a display is attached… bad Job ;)
I can select them as devices for I-Ray yet there is an error
message when I start rendering:

Autodesk suggests this to be a driver issue and suggest I should uninstall all the cards
and add them aknew one by one. Trifling task though I think this got to be achieved easier.
Also I did open this post because they recommended me to do so.
Any suggestions so far? It would be pretty neat to use them in addition to the CPU or in RATgpu
for example. The cards would not be used any more, but to say they are of no use, I refuse.
Kind regards
Daniel
