Upon completion of the first row memory test, the memory testing continues with the base memory
test.
If the first row test fails, there are several possible failing cases. Two failing scenarios are described
in the following sections.
Case 1
The first row memory test encounters a MBE (Multi Bit Error) in the first populated row of memory
configured. Irrespective of the number of DIMMs populated in the system, if the first row test
encounters a MBE, the BIOS will display an error message on the front panel 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.
"First row test"
"Failed, sys halt"
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.
