Hi there!
Do you know of any popular DOS game released after 1988 that has trouble with a 64MB setup?
No, not really.
However, please make sure there's enough cache memory installed.
Otherwise, the memory performance will be impaired ("cacheable area").
Also, make sure you use the Himem.sys from MS-DOS 6.x or similar! 😀
Otherwise, XMS memory will be limited to 16 MB.
Another stumbling stone might be the 15-16MB area.
It's at the end of the ISA bus (has 16MB wide address space).
That region sometimes serves a similar purpose as the UMA (640KB-1MB).
Graphics cards and other devices may use it for accesing their buffers, because developers did not expected consumers to have that much memory installed.
So in theory, parts of the memory of your 16-Bit VGA (linear framebuffer etc) could overlap with your system memory.
If that's the case, just enable the "memory hole" option of your CMOS Setup.
Good luck! 🙂🤞
Edit: BitWrangler was quicker! 😃
