Yes, the memory is probably defective. But this kind of defective RAM is installed in many systems today, because the access pattern used by the rowhammer exploit is never found in real-world work loads, so they never tested for it.

MemTest86 v6 includes a test for rowhammer (test 13), but prior to that, MemTest86 didn't detect the rowhammer fault either.
