5. If problem continues to recur on the same DIMM, re-inspect DIMM connector for foreign material and remove
any foreign material that is found. If the connector is damaged, replace the system board.
6. Remove the affected processor and inspect the processor socket pins for damaged or mis-aligned pins. If damage
is found, or this is an upgrade processor, replace the system board. If there are multiple processors, swap
processors to move the affected procesor to another processor socket and retry. If problem follows the affected
processor or there is only one processor, replace the affected processor.
