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, quad, or octal).
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 374
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
372 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, quad, or octal).
c. Replace the memory card.
3.
If more than one DIMM was recorded, and the DIMMs reside in more than one group (pair, quad, or
octal):
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, quad, or octal):
a. Replace all of the failing DIMMs.
b. Replace the memory card.
Boot the system to the SMS menus. Power off the system and go to the service processor Memory
Configuration/Deconfiguration Menu to verify that all memory DIMMs are in the configured state after
the repair action. Go to ″MAP 0410: Repair Checkout″ in RS/6000 and Eserver pSeries Diagnostic
Information for Multiple Bus Systems.
