How to fix this

I'm trying this, waiting for the next epoch

Also try increasing the size of your page file.
My page file set at 20000MB, do I need to increase?

Depends how many cards you have. If you have 6+ then yes you should increase it. The page file has to be big enough to hold the DAG for all GPUs in the system.
Current DAG size is 2.65 GB
6 cards = 15.9 GB = 16281 MB
7 cards = 18.6 GB = 18995 MB
8 cards = 21.2 GB = 21709 MB
And so on those numbers will only get larger as the DAG continues to increase.
