Memory card with 1600 Mhz speed but listed as 1333 Mhz in system info
They aren't identical despite matching specifications. I inserted both units and adjusted the unusual one to 1600 MHz CL11, which should be the default setting, then tested with MemTest64 to check for stability problems.
The results pictured do not show any XMP profile. It just isn't there. Even in systems that don't support XMP operation, usually it can still be read. You might also want to try Thaiphoon Burner for one more go. That really digs into the details, but I doubt it'll report any differently. Note even if there was an XMP profile, that is not necessarily the "out of box" running setting. Generally speaking systems will run at the highest SPD speed officially supported by the CPU. There is no profile above 1333, so that's the fastest it'll run without manual adjustment.
