Error Code Description
Memory Error Notes
Use the location code obtained from the SMS Error Log utility (described in "Step 1020-4" on
page 48) to identify which memory DIMM (or memory DIMM pair) the error is reported against.
Memory error codes are in the form 25Cyyxxx where yy indicates memory DIMM present
detect-bits (PD-bits) and xxx indicates the last 3 digits of the error code.
See Table 4 on page 176 for information on how to interpret PD bits.
25B00001 No memory DIMMs detected.
25B00002 Multiple memory DIMMs failed a memory
25Cyy001 Memory DIMM is not supported.
25Cyy002 Memory DIMM fails memory test.
25Cyy003 PD bits are mismatched or missing one
25Cyy004 Memory DIMMs are disabled.
25Cyy005 Memory DIMM failed address test.

Action / Possible Failing FRU
Go to "MAP 1240: Memory Problem
Resolution" on page 49.
Go to "MAP 1240: Memory Problem
Resolution" on page 49.
Replace unsupported memory DIMM.
Note:
Memory DIMM must be replaced with
a supported type of memory DIMM. If
an unsupported memory DIMM is
replaced with the same unsupported
type, the error persists.
There might be two memory
module-related memory errors
reported to indicate a memory DIMM
pair. One of the two indicated memory
DIMMs may be good. When replacing
memory replace one memory DIMM at
a time, not both.
See Memory Error Notes on page 126
for more information.
Go to "MAP 1240: Memory Problem
Resolution" on page 49.
1. Make sure both memory DIMMs in
the pair are present and are the
same type.
2. Go to "MAP 1240: Memory
Problem Resolution" on page 49.
1. Use the memory config/deconfig
menu in the Service Processor
System Information Menu to check
the status of the memory DIMMs.
