Chapter 4
8C82: Errors found in memory subsystem. Failing rows will be mapped
out on the next reset. It is strongly suggested that you reset the
system now.Allowing the system to continue to BOOT may result in
unstable system behavior and/or hard disk corruption.
Hit <F1> to load defaults or <F2> to run SETUP or <ESC> to continue
The first line will be seen for each DIMM that on which the extended memory test has found an error. This
message will NOT be seen on subsequent POSTs.
The second and the third line will be seen each time a memory error was found by the extended memory
test.
User Action
Upon getting the notification of memory errors during extended memory testing, HP strongly recommends
that the server be reset by pressing the reset button. On the subsequent boot, the defective DIMMs, found
during extended memory testing, will be mapped out and will not be available as part of the useable memory.
Failure to do the reset would result in an unstable behavior of the system.
Under 'User Notification' in Example #2, the following error message can be seen if the system is reset.
32768 MB Total Memory Installed
30720 MB Configured
30720 MB Tested
8C9B: DIMMs mapped out: Upper Board, 17-20
NOTE:
Error Logging
For the extended memory test, four error records will be written for multi-bit errors, one for each DIMM. For
single-bit-errors during the extended memory test, error records will be one per DIMM. By specifications, the
DIMM number will be one less than the silk-screened number on the printed-circuit board. Please refer to
Error Log Format Specification Version 0.7 for details on the format of the error records.

Memory Test Duration

The time it takes for memory test depends on the size of memory and the exact population scheme. The
more memory that is tested, the longer this test takes, with a full test taking a significant amount of time. To
alleviate this problem, skipping memory locations can be done, but this does not exercise the entire memory
subsystem. To reach a compromise, there will be CMOS Setup options available to the user. These CMOS
options will allow a user to select a quick memory test or an exhaustive one. Refer to the section on "Setup
Dialog" section below for more information on the options.

Aborting the Memory Test

Users are given the option to abort the memory test by pressing the spacebar. The following string will
appear on the bottom of the screen when executing the extended memory test:
Press spacebar to abort memory test.
However, this method will only work for the extended memory test, but not for the first row or base memory
tests. The total amount of memory installed in the system will still be reported on the video screen.

Setup Dialog

The BIOS setup (F2) menu has the following selections:
->Advanced->Chipset Configuration->Memory Related Items:
On the above example, we do NOT see "Memory Errors Detected", because the
defective memory has been mapped out. This is shown because the second line
configured size is less than the first.
