I have been involved with DIMM for years. First, although all DIMM connectors look alike, they all do not function the same. Both the module gold pads and connector contacts need to be clean. The reseat issue is not unusual especially if cheap connectors are used or the manufacturing environment is not clean allowing debris to settle into the connector. Also, some DIMM makers don't treat the gold contact area on the module as the contact interface it is. Gold flash can be a problem. No or this nickel underplate is another.
