Hi,

I have run into some problems with my render slave machine running windows 10. Its a Supermicro (https://www.supermicro.com/products/sys ... 8gr-tr.cfm)

At some point yesterday it showed me all 4 GPU's, (NVIDIA 980 Ti) but now it can only register 1 of them.

I have tried to install CUDA driver 7.5 from version 8 to see if that would change something, but it wont.

I have hardware monitor on that can see all 4 of them active, but inside Octane Standalone it only gives me 1 of them.

Heres the list from CPUID

Heres the view in Octane standalone

Im really in need of help here. Thanks guys!

Hi,
unfortunately this is not the best section to post this kind of questions, the best is to write in the General support or GPU and Hardware sections, I guess.
Maybe I have misunderstood, but you don't need to install specific CUDA drivers in Windows, please try with a fresh clean reinstall of the latest Nvidia display drivers :roll:
