Hi,
in light of current CUDA errors you reported, could you please try as follow:
1 Updates windows 10 up to at least build.
2 Right click the Start button and select Control Panel.
3 Make your way to System and Security.
4 Click System.
5 Click Advanced system settings from the left sidebar.
6 Select the Hardware tab.
7 Press the Device Installation Settings button.
8 Choose No, and then press the Save Changes button.
9 Unistall the Nvidia drivers using DDU Nvidia unistaller drivers safe mode unistall - windows safe mode

10 - install this 442.92 studio Nvidia driver standard mode (not DHC)
http://us.download.nvidia.com/Windows/4 ... d-whql.exe
please doesn't install GeForce Experience and make a clean installation.
To start your test, please active the Out-of-core then set the head room to 512MB, parallel sample to 2 and max tiles to 4.
My personal idea about a good hardware configuration to render is:
1 GPU to connect monitor/s (Windows and applications will use this GPU and VRAM to work).
It is deactivated in Octane. I will use it for denoiser.
1 or more GPU active in Octane.
Minimum 64 GB Ram (3dsMax as other applications eats Ram).
Then I will set 512MB head room (you can try 1024MB but it depends on VRAM available).
With very large scenes increase parallel sample and Max tile starting from 2/4 > 3/6 > 4/8..
And last but not least, optimize scenes e.g. having a very high poly forest with 8k textures away from the camera 500 meters will not make your render more beautiful but will eat a lot of VRAM or use Greyscale image texture node (specular, roughness, opacity, bump, diplacement ..) when needed instead of RGB image texture node.
Avoid grouping objects that create high amounts of polygons and textures. VRAM better manages small data packets.
Make all proxy movable.
