I am debugging a DDR3 issue on our boards. We put DDR3-1600 parts from
Samsung, Elpida and Nanya parts on these boards, of course, each board is
installed with the drams from the same vendor. For some reason, only those
boards installed with Samsung parts work stable. Those board installed with
dram from the other two vendors has  trouble running at 1600Mbps. These
parts should all be qualified for running DDR3-1600. Does anyone has any
idea what to look at first?
