CUDA Failure - Troubleshooting

I have a large scene, 10GB ORBX file.
I have 2 x 2080 with 8GB each. Since the file is so large, I added 55 GB of my 64 GB of RAM to be "OUT OF CORE" memory.
I am still getting a failure from both GPUS despite this. I am wondering if it is normal that 10GB file cannot fit into all this out of core memory and if there is anything else I can do to run this file with success?
