Memory-Related Error Codes
You have been directed here because you have an 8-character error code that
indicates a problem with system memory. This section will help you isolate to the failing
FRU.
v If the location code or the service action calls out one DIMM, do the following:
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 DIMMs state (see ″Memory
Configuration/Deconfiguration Menu″ on page 260 for more information), then do the
following:
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 258 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).

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.
