Handling of Uncorrectable Errors

This section lists facts and considerations about how the server handles uncorrectable errors.

Note – The BIOS ChipKill feature must be disabled if you are testing for failures of multiple bits within a DRAM (ChipKill corrects for the failure of a four-bit wide DRAM).

■The BIOS logs the error to the SP system event log (SEL) through the board management controller (BMC).

■The SP's SEL is updated with the failing DIMM pair's particular bank address.

■The system reboots.

■The BIOS logs the error in DMI.
