1. Check the IBM support website for
an applicable retain tip or firmware
update that applies to this memory
error.
2. Swap the affected DIMMs (as
indicated by the error LEDs on the
system board or the event logs) to a
different memory channel or
microprocessor (see “Replacing a
memory module” on page 313 for
memory population).
3. If the error still occurs on the same
DIMM, replace the affected DIMM.
4. (Trained technician only) If the
problem occurs on the same DIMM
connector, check the DIMM
connector. If the connector contains
any foreign material or is damaged,
replace the system board (see
“Removing the system board” on
page 354 and “Replacing the system
board” on page 359).
5. (Trained technician only) Remove
the affected microprocessor and
check the microprocessor socket
pins for any damaged pins. If a
damage is found, replace the system
board (see “Removing the system
board” on page 354 and “Replacing
the system board” on page 359).
6. (Trained technician only) Replace
the affected microprocessor (see
“Removing a microprocessor and
heat sink” on page 347 and
“Replacing a microprocessor and
heat sink” on page 349).
