Memory-Related Error Codes

v
If the location code or the service action calls out one DIMM:
1. Replace the memory DIMM.
2. Replace the memory group (pair or quad).
3. Replace the memory card.
v
If more than one DIMM is called out, go to the service processor memory
configuration/deconfiguration menu to verify memory DIMM state. See

on page 384 for more information.
1. From the Memory Configuration/Deconfiguration Menu, select the card(s)
specified by the location code(s) of the failing DIMM(s). If the first character of the
error status of any DIMM is 1, 2, or 3 (but not 0 or 4), this is a suspect DIMM.
Record its location. See “System Information Menu” on page 382 for more
information on the error status of the DIMMs.
2. If only one DIMM was recorded in the previous step:
a. Replace the DIMM.
b. Replace the memory group (pair or quad).
c. Replace the memory card.
3. If more than one DIMM was recorded, and the DIMMs reside in more than one
group (pair or quad):
a. Replace the memory card.
b. Replace all of the failing DIMMs.
4. If more than one DIMM was recorded, and the DIMMs reside in one group (pair
or quad):
a. Replace all of the failing DIMMs.
b. Replace the memory card.
v Boot the system to the SMS menus. Power off the system and go the service
processor memory configuration/deconfiguration menu to verify that all memory
