No cuda device when onboard vidio enabled

[amathews9518]

As soon as I enable onboard vidio octane doesn't recognize cuda device.
It shows up in device manager though.

Go into your LW > Octane Render > Plugin Options > GPUs - and make sure your GPUs that you want to use are enabled.

there is no gpu devices showing to enable.
When I go into bios and select onboard vga as main gpu LW shows no gpu available.
When I set pcie as display in bios then they become available in LW.
I am trying to set onboard vga as display so I can use cuda gpu at full speed.
Device manager shows them as working but does not show up in Octane

Did you just start using the 3.0.6 version by any chance? And if so, did you install the latest nVidia driver?

[amathews9518]

Using 3.05 & installed new driver.
I even tried setting onboard vga in bios & then install newest driver.
Windows recognizes both 780 cards but Octane does not.

Well, that is a head-scratcher... I was under the impression that plenty of Octane folk use integrated GPUs. I myself do not, so I have nothing else to offer you friend. Hopefully someone else will come to the rescue...

I feel pretty confident that this is not a LW Octane thing.. You should post this over in Commercial Support Forums > Video Cards / GPUs and Drivers. You will be way more likely to get help with this.

Yes, you should post this issue in the general forums. It doesn't seem related to the LW plugin (probably the Standalone has the same issue), and you could get more help there.

I don't know why this can happens. Perhaps something related to your BIOS settings, who knows.

Thanks,

Thanks.
I posted this in commercial forums.
This may be a limitation of the mother board.
I have changed settings in bios with no results.

did you check if CUDA cersion 8.x was installed? with version 7 octane will not show any GPU.

cheers
