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

Did you redownload the latest nvidia drivers?
I had some issues recently where cards weren't being recognized but when i switched the power cable to the cards they both worked. Makes no sense but it did the trick for me

You could give this a try..might help, might not.

It will clean out the currently installed drivers and associated gunk, then set a flag so Windows10 won't try to auto-install new drivers.

Download drivers directly from Nvidia, install and restart.

no chance!

used that tool to deinstall all drivers.
Changed power cables.
Changed order in slots.
All cards have same newest driver installed.

After every restart I get different info in hardware manager.

It seams, that the system (Win 10 Home 64) does not allow
to use 2 Grafikcards the same time!
(As said, with Win 7 Home 64 everything worked well)

Is there a configuration I have to change to tell
Windows to use both (or all 3) cards?
Back to Win7 ?
Any other idear?


thanks much

Hi,
Have you verify if there is a new bios update for your motherboard?

bepeg4d,

thank you very much!

A very old bios caused that problem with Win 10.
I updated bios to newest version.

Now it works!!!!!!!
