Error logging
During the boot sequence following an uncorrectable memory error, the ROM BIOS will display an
error message similar to that shown in Figure 4.

HP integrated Lights-Out (iLO) software logs the memory error information (Figure 5) so that you can
easily identify the faulty DIMM from a remote console and replace it during the next maintenance
cycle.
