The BIOS setup utility executes a memory test prior to configuring
the memory in POST and when a memory board is inserted into
the system during a memory hot-removal or hot-add operation.
If a DIMM fails the memory test, an LED will light on the memory
board to identify the location of the bad DIMM and the DIMM
bank will be disabled. The failed DIMM is logged onto the System
Event Log (SEL). BIOS setup utility will disable the DIMM and/or the
memory board. Upon subsequent reboots, this memory is not
initialized unless the BIOS setup option “Reset all system memory”
or “Retest board memory” is selected. Refer to “4 BIOS setup” on
page 101 for more information.
