The following is an example with a memory compare error indicating bad DIMMs.
In most cases, the failing bank and DIMM position (Figure 3-1) are specified in the
error message. If the failing DIMM information is not provided, use the procedure
that follows to isolate a failing DIMM.
>>> memexer 3
*** Hard Error - Error #41 - Memory compare error
Diagnostic Name ID Device Pass Test Hard/Soft 11-NOV-1997
memtest 00000193 brd0 114 1 0 12:00:01
Expected value: 25c07
Received value 35c07
Failing addr: a11848

>>> kill_diags

To find the failing bank, compare the failing address (a11848 in this example) with
the show memory display or memory portion of the show config command display:
1. Banks with no memory present are eliminated as possible failing banks.
2. If the failing address is greater than the bank starting address, but less than the
starting address for the next bank, then the failing DIMM is within this bank.
(Bank 0 in the example using failing address a11848 and the following memory
display.)
>>> show memory
Memory
128 Meg of System Memory
Bank 0 = 64 Mbytes (16MB per DIMM) Starting at 0x00000000
Bank 1 = 64 Mbytes (16MB per DIMM) Starting at 0x01000000
