Chapter 11
User Action
This memory failure must be fixed and can only be fixed by replacing the bad row
of DIMMs.
1. Replace the first row of DIMMs. Determine the location of the defective
row using Table 11-2. Starting with #1 in the "Order" column, determine
the "DIMM" locations (5-8 in this example) and memory board (upper in
this example). If memory is populated in these DIMM locations then this
is the first row and has defective memory. If not, the next set, if populated,
becomes the first row. Repeat until you have determined the first memory
row. 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.
Error Logging
The defective row/DIMM(s) found during this test cannot be logged to the SEL or
reported on screen.
Case 2
The system is populated with only one row of memory and the first row memory
test encounters a SBE (Single Bit Error). In this case, the BIOS will write these
rows into CMOS history, map out the only row of DIMMs, 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"
"0064MB"
"ALL DIMM MAP OUT"
Example 1: Consider a system that is populated with only one row of 256 MB
DIMMS in the upper board row 1-4. If an SBE was detected in DIMM 1 during
the first row memory test, the following message will appear on the LCD:
182
- displayed on the upper LCD line
- displayed on the lower LCD line
