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.

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.
