I have a faulty board I think. 95% of the time when starting it I get three long beeps (I had to add my own speaker) and code 21 on the panel. Renegotiating the RAM in the slots sometimes fixes it and then it runs flawlessly, but there's no guarantee it will boot again the next day, even if the device is unmoved.

Can I get confirmation from the board that code 21 is a memory addressibility issue before I RMA this? I assume it just has a defect I have the DIMM slots making the connection unreliable.
