Have you checked the manufacturer's website?  Perhaps look up for the
Motherboard specs?
It will tell you if DDR3 is supported or not(should have 2 DDR3 memory
modules and 2 DDR2 modules), but AFAIK DDR2 400Mhz are far beyond frequency
from DDR3 which runs at 1333Mhz and most of the motherboards I assembled
which support DDR2 400Mhz will only support frequencies up to DDR2 667Mhz.

So I think you should return your memory modules or get another ones based
on your motherboard's specs.
