Can't get both GPUs working together in Ubuntu Tweet

[edwardflorance_msoa]

I'm having trouble getting two GPUs rendering at the same time in Ubuntu.

The two GPUs are a GTX 780Ti and a GTX 580, which each work on their own if only one is activated in the Octane settings, but has the 780Ti fail if both are activated.

I have a feeling it might be a driver issue, but if anyone could point me in the right direction for getting them to both work together that would great!

Thanks

Yes, it could be a driver issue, try to update the driver and CUDA aswell. If the 780TI is overclocked then try bringing it down or underclock and see how it goes.
