If it's listing more than a screenful of info then you got SEVERE problems. If it is the memory stick, then it's garbage.
But it could be the actual memory stick or it could be the motherboard, or it could even be the CPU (unlikely). There is no way for Memtest86, or any memory test, to know for sure. You could bring your stick of memory down to a local computer store and see if maybe they have memory tester.
