Yes, I've cleaned the edge connector twice, pencil eraser and Deoxit.
Then DeOxit the Molex connectors on the AR, and reseat them a few times.
Also, you should get the fiberglass pen, as it's more abrasive than a pencil eraser. You really need something slightly abrasive to break up the microscopic layer of oxide that builds up on the fingers.
Also, make sure the test points on the AR are clean. You can get the same buildup of crust and/or other grime on them that can cause unstable voltage readings. Take some fine sandpaper and hit the test points with them so they are bare, clean metal. That way you know you're getting solid readings.
More concerning is I'm getting two beeps but never in test mode...test mode shows all is well...
This is why I suspect the issue is more likely a logic failure that is screwing up the bus, causing the CPU to think there is a RAM error, when there isn't one. (If it really was a bad RAM, it should show up in test mode.)
