ello,
i'm trying to fix a GPU computing issue.
I have two RTX A5000, and Octane renders properly if u use just one or the other GPU, but not if i use both.
I tried all sort of tests, from Furmark to OCCT, i ran in-depth tests and Hardware seems look ok.
I removed latest windows update, which is known for being buggy with GPUs, but problem is still here. Everything was working until past week, then all of a sudden this issue appeared. I changed nothing in HW or SW, just the windows update that i removed afterwards.

I also removed both A5000 and plugged a 3090 (with proper driver), and Octane perfectly works.
It looks pretty much a multi GPU support (octane is not faulty on this since it works on other machines with same software setup).
Any advice about how to fix this ?

Thanks in advance
Paolo

I sadly think this question is a bit beyond the scope of knowledge this server offers, have you tried contacting nvidia directly?
