I'm going to buy Enterprise edition this month. At the moment I'm using demo version and I can say that NV Link doesn't work at all. I have two RTX 2080ti. I had out of memory errors, too many polygons etc. Or Octane demo doesn't support NV Link ?

Ok NVlink is enabled but not functioning as it should. Crashes and out of memory like using one RTX card without doubled GPU RAM.

NVidia Driver - 431.70 - stable rendering ( last few days 5000+ frames ) scenes around 5-8mln poly
NVIDIA Driver ( latest ) 436.15 - unstable / crashes randomly ~100-150frames

Creator ready? I've seen some reports about stability issues on latest driver.

Did you tried DDU before installing it ?

How were you able to get it running in Octane?
I also made the NVLink Test with the tool you mentioned and its working. Still, no luck with Octane.

Is it true that only Quadro and Titan NVlink bridges doubles GPU memory ? I have Gigabyte Aorus bridge - it is the problem ?

Some technican from Nvidia said that Titan bridges are neccessary for double GPU RAM NVLink feature. So I bought one Titan RTX NVlink bridge and still get this :
I suppose that this Octane NVLink "feature" is only for advertising...
Peers from Octane Device Settings panel are always reseting to off state - maybe this is the problem ?
In Octane Standalone it works fine.
