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”
- displayed on the upper LCD line
“0064MB”
- displayed on the lower LCD line
“ALL DIMM MAP OUT”
- displayed on the upper LCD line
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:
“First row test”
- displayed on the upper LCD line
“0064 MB”
- displayed on the lower LCD line
“ALL DIMM MAP OUT”
- displayed on the upper LCD line
User Action
1. Replace the first row of DIMMs. On repacing 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 case cannot be logged to the SEL or reported on screen.
Base Memory Test
Description
The Base Memory Test will take effect after the completion of the first row test with no errors, or with single
bit errors, and if the system contains more memory to test. The base memory test will test the first 2 GB of
