Chapter 11: Troubleshooting
1. Determine the location of the row of defective DIMMs from the error message or by running
the EFI based SELViewer Utility or by running either the Intel Server Control (ISC) or Direct
Platform Control (DPC) to read the System Event Log (SEL). Replace the defective DIMMs
(in the example it is 5-8). 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 bad
DIMM history.
3. Power on the system to continue.
Error Logging
The defective row/DIMM(s) found during this test case will be logged to the SEL and reported on the
screen.
Case 2
The system is populated with more than one row of memory and the first row memory test encounters
a SBE (Single Bit Error). The base row test encounters memory errors on all the rows. In this case,
the BIOS will write the failing row from first row test into CMOS history, map out the first row of
DIMMs, and continues with base memory testing. The base memory test will write the failing rows
into CMOS history and map out the defective rows upon reset. If all the memory in base memory (<
2 GB) is mapped out due to memory errors, then the system will display a message on the LCD and
halt the system.
User Notification
This memory test occurs during POST and prior to video sync. Therefore, any error found during this
test will result in the following message displayed on the LCD panel and the system will halt.
"First row test"
"0064 MB"
"BASE MEMORY TEST" - displayed on the upper LCD line
"ERRORS IN MEMORY" - displayed on the upper LCD line
"RESETTING SYSTEM" - displayed on the lower LCD line (prior to resetting if an error was
Upon reset, you will see the following messages on the LCD:
"First row test"
"0064 MB"
"ALL DIMM MAP OUT" - displayed on the upper LCD line
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"
