need help with second grafic card on win 10 please

[miohn]

Hi,

my second pc which I use as slave has a titan z for rendering with octane.
And I had (before with Win 7) a second GTX 560 Ti which is deactivated for octane but
usefull for the system or surfing in the web etc..

But with Win 10 I cannot get both cards to run.
Either the titan Z gets no driver and a yellow sign in the hardware-manager
or it happens with the GTX 560. Or the other way round.

Has anyone experience with Win 10 how to get 2 cards running?

thanks
Mike

Is everything up to date? Driver version?

Hi Tos,

yes of course latest NVidia Drivers.
Installed one card after the other.
When I change the cards in the pci slots, the
first card has prober drivers installed and the second failes.
And vice versa.

Nothing seems to help.
With Win 7 64 I had no problems.

(Btw I have a 1000W PSU)

regards
Mike
