sequence).
3.
If the error still occurs on the same DIMM,
replace the affected DIMM.
4.
(Trained service technician only) If the problem
occurs on the same DIMM connector, check the
DIMM connector. If the connector is damaged,
replace the system-board assembly (see
“Removing the system-board assembly” on page
