Chapter 5.3 Memory Related Error Codes
Memory error codes result when the system detects a memory fault during the
Power On Self Test or diagnostic test.
The Test programs attempt to isolate
the memory fault to a specific chip, then generate a memory error code that
identifies the defective memory chip.
In some cases, replacing the memory chip will not solve the problem because:
o
The system may not be able to accurately determine which chip or chips are
at fault.
o
The problem may be caused by 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 type of system, the number and
type of memory boards installed, and the type of memory device used
(64K x 1 Bit RAMs or 256K x 1 Bit RAMs).
Tables 5-14 through 5-17 identify which memory device to replace when the
system shows a memory error.
Table 5-13 indicates the table to reference to
locate the defective chip.
