16 unknown, possibly something related to memory size
2049 unknown, possibly something related to memory size
DIMM0 -- that is telling you EXACTLY which RAM memory DIMM has failed
J21 is telling you the component-slot number in which the failing DIMM is installed
its not ambiguous. you have at least one memory module that is not working adequately.
