Hello ,I have 3 nvidia 2080 founders editon connected to a dual xeon asus motherboard. Although they are not connected via nvlink, octane renderer sees the memory as 24 gb ı guess(available is about 18gb)
And ıt works when ı open a small scene. When ı try to render a loaded scene 3dsmax crashes. My assumption is that it is a nvlink-memory problem. I am using octane 2018 xb2 3dsmax plugin with 3dsmax 2019.

Hi umut_sert,
there is a known issue about the VRam that Octane shows. Without Nv-link bridge your available VRam is 8GB.
Without Nv-link bridge, you can only use CPU limit option.
anyway, try taking a look here:
