Extended Memory Test - HP Integrity rx4610 User Manual

Chapter 11: Troubleshooting
User Notification
The BIOS will try to map out defective rows found during base memory test but will end up in an
infinite reset loop.
"First row test"
"0064 MB"
"BASE MEMORY TEST" - displayed on the upper LCD line
"ERRORS IN MEMORY" - displayed on the upper LCD lin
"RESETTING SYSTEM" - displayed on the lower LCD line (prior to resetting)
Upon reset, the above messages will display again on the LCD and will keep repeating in an infinite
loop.
User Action
1. Use the out-of-band mechanism of reading System Event Log (Intel's Server Management
software, specifically DPC, can be used for this) to determine the location of the row of
defective DIMMs from the 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 defective
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
screen.

Extended Memory Test

The extended memory test takes effect after both the first row test and the base memory test have
passed. The Extended Memory Test will test the physical memory above 2 GB to a maximum of the
total installed memory. Any errors found will be detected to the failing memory row and recorded
into the CMOS history bits for processing during the next reset. Since this occurs after system POST,
the BIOS will not reset the system. Instead, error messages will be displayed on the video screen.
There is a 2 GB fixed gap between the memory address 2 GB to 4 GB that is reserved for PCI. This 2
GB of memory addresses, as seen by the processor, will not be tested.
User Notification
There are two sets of messages associated with this test. The first occurs when the test is being
performed. The message is as follows:
XXXXX MB Total Memory Installed
XXXXX MB Configured
XXXXX MB Tested
Memory Errors Detected (will appear only if extended memory test
finds errors).
The first line is the total memory installed (regardless of condition). The second line is the total
memory useable (and is less than the first line, only if defective DIMMS were found). The third line
- displayed on the upper LCD line
- displayed on the lower LCD line
