I don't think it's just because of DDR SDRAM. DR EMM386 works for me
on a machine with 1024 MB DDR SDRAM, although multitasking does not
work and I haven't yet figured out why (the machine isn't mine and
I don't use it too frequently, particularly under DOS).

Please [tell him/her to] try excluding manually C000-EFFF area;
using MS EMM386; using HIMEM only; disabling DPMS.

More details on hardware configuration (mainboard, chipset, CPU,
add-on cards, RAM size) could be helpful as well -- maybe someone
has some experience with similar hardware?

Hope this helps,

Michal
