Chapter 6.4 Memory Error Codes
Memory error codes result when the system detects a memory fault during the
Power On Self Test or as a result of a DIAGNOSTIC test. The TEST programs
attempt to isolate the memory fault to a specific chip, then generate a memory
error code that identifies the system board, memory board, or the defective
memory module to replace.
In some cases, replacing the memory module will not solve the problem because:
o The system may not be able to accurately determine which module is at fault
if multiple memory errors are detected.
o The problem may be due to a failure in the memory support circuitry, not
the memory.
The memory error code points to a specific memory address. The physical
location of the memory address depends on the memory expansion board or memory
module used.
