Can you safely disable the pagefile?

If you run out of free memory, including virtual memory, the system cannot continue to guarantee deterministic execution, and ends itself. Before that happens, the operation system will do various other things such as killing programs that use too much memory. What I want to say is, memory is always finite, and every OS can deal with this. Therefore limiting total available memory to 64 GB won't harm Windows - many systems can't go beyond 8 GB even with a pagefile, because with 1 or 2 GB RAM the pagefile is usually a lot smaller than 6 or 7 GB.

Does it make sense to put the pagefile on a ramdisk?

To increase the available memory, most if not all advanced operating systems use some kind of swap file where they take some memory that's in RAM and hasn't been accessed for a while, write the memory to the harddisk (swapfile aka pagefile), and delete the memory from the RAM so that more fast memory is available. The swapfile is used to extend the maximum size of the memory beyond the size of the available RAM.

Therefore, using a ramdisk (which reduces available memory by the size of the ramdisk) to host the swapfile (which increases available memory by the size of the swapfile) will work, but it won't make a lot of sense. It will not offer more memory than disabling the pagefile, yet it will still require the system to run paging algorithms.

It should be noted that as long as you have an excessive amount of unused RAM, the overhead of the OS maintaining a pagefile will not be measurable.
