Troubleshooting

Example: Consider a system is populated with two rows of 256 MB DIMMS in
the upper board row 1-4 and row 5-8. If an SBE was detected in DIMM 5 during
the first row test and an SBE\MBE was detected in DIMM 1 during the base
memory test, then the following message will appear on the LCD:

“First row test”

“0064 MB”

“BASE MEMORY TEST”

“ERRORS IN MEMORY”

“RESETTING SYSTEM”

Upon reset, you will see the following messages on the LCD and the system will
halt:

“First row test”

“0064 MB”

“ALL DIMM MAP OUT”

User Action

1. Determine the first row of DIMMs using the scanning order defined in

Table 11-2. Replace the first row of DIMMs with known good DIMMs.
On replacing the DIMMs, make sure the size and HP part number match.

2. Clear CMOS via the front panel or via clear CMOS jumper in order to

clear previous defective DIMM history.

3. Power on the system.

NOTE

The defective rows of DIMM found during base memory test
can be determined once the system boots from the “DIMMs
mapped out” message. Then, those DIMMs can be replaced, if
needed.

Error Logging

The defective row/DIMM(s) found during the base memory test will be logged to
the SEL. This includes both single-bit errors (SBE) and multi-bit errors (MBE).
