real memory = 1649265344512 (1572862 MB)
avail memory = 1057138888704 (1008166 MB)
..

I suspect address space issues, but don't know for sure.
Changing NUMA nodes per socket in the BIOS had an influence to make it
worse, but not better.

real memory = 1649265344512 (1572862 MB)
avail memory = 1057118396416 (1008146 MB)
Real memory is really the max physical address of the valid byte.
If you have holes in the phys map, real memory should reflect these
holes. Avail memory is the total memory as reported by EFI map.

Verify all that by looking at sysctl machdep.efi_map output.
