Scenario 2: DIMM-A Failure code:2000-0123

I have run diagnostics and I get the same failure on DIMM-A. I even changed the RAM stick to a new one and get the exact same error in Dell Diagnostics.Error Code: 0123 Msg: Error Code 2000-0123 Memory Integrity test fault. It is a Vostro 1700. I took the RAM out of DIMM-A all together and it is running diagnostics fine. Does this indicate a bad slot DIMM-A only or I am facing motherboard failure? It is out of warranty.
