Referring to the post on the link below, the size of NonePagedPool cannot exceed 128GB no matter how many RAMs are added to 1TB or more.

I am currently developing a program using a technology called RDMA, and in order to register memory in RDMA, I must register in the NonePagedPool area 1TB.

In a Linux environment, you can lift restrictions in the following ways

Let me know if there is a way to declare the size of a similar, NonePagedPool above 128GB in Windows

    A modern RDMA driver should be able to use pinned memory like Linux rather than non paged pool.
