Following up on the very same topic as this thread,

I'm now trying to work out if adding 4x Samsung M393B2G70BH0-CK0 16GB on this Supermicro H8DGi board, my memory will go to 1600MHz.
Also I skimmed through the motherboard manual and I don't quite get the 128/64-bit reference on page 2-8
Finally I'm confused on the manual statement that says:

"Install to slots CPU1/DIMM1A, CPU1/DIMM2A, CPU1/DIMM3A and CPU1/DIMM4A, etc. Always install in groups of four and in the numerical order of the DIMM slots. See support information below. "

This table suggests that my memory modules shoud be ok:

However, does this motherboard really need 4x modules per CPU (so 8 modules since it's a dual CPU) to work efficiently? How about 2x 16GB per CPU? The image is not clear in regards...

Thanks!
