9.
If any DIMM has been marked as disabled for “MemBIST Fail ure ” (does not include “SPD Failure” or “Population
Error), assuming the there are still usable DIMMs available in the system:
x The BIOS sounds a memory error beep code.
x Error Manager Major error codes 0xE6xx (Memory BIST Failed) and 0xE1xx (DIMM disabled) are displayed
and logged to SEL for each DIMM that failed and was disabled.
x The System Status LED is set to AMBER/ON.
10. For all DIMMs disabled
as either “MemBIST Failure”, “SPD Failure” or pPopulation error:
x DIMMs are excluded from memory amount displayed in POST.
x DIMMs are shown as “Disabled” or “Failed” as appropriate in Setup Memory Display.
a. MemBIST Failure shown as “Failed”.
b. SPD Failure shown as “Disabled”.
c. Population Error shown as “Disabled”.
x DIMMs are coded as “Empty Sock
et ” in SMBIOS Type 17 structure.
x DIMMs are excluded from SMBIOS Type 19 address ranges.
x DIMMs are not included in SMBIOS Type 20 structures.
x
DIMMs are mapped out in SMBIOS Type 131 structure.
11. If any DIMM is disabled
, regardless of the reason:
x If RAS Mirrored Mode is configured:
a. The memory system falls back to max performance mode.
b. A SEL event is logged for RAS State
 Configured Mirror Mode, lost redundancy, operating in degraded
state”
.
c. Error Manager Major error code 0xE4FCEc (Memory was not configured for selected RAS mode) is
displayed and logged to SEL.
16.2.12.2.4 Memory Population Error
BIOS will disabled the DIMMs installed in wrong DIMM slots. Error manager will have 0xE1xx(DIMM disabled). BIOS
will also send SEL Memory Mismatch/Confuguration error to BMC.ED2[3:0] will have Population error bit set.Refer to
section 2.2.11.2.2.2.
16.2.12.2.5 BIOS Diagnostic / Error Screen

Configuration Error Pause 0xE4FC Memory was not configured for
selected RAS mode
Failure of BIOS to configure the
memory system in the selected
RAS mode.
DIMM failed BIST Major 0xE6xx DIMM_xy failed Self Test (BIST). DIMM failed during POST
Memory BIST.
Memory Disabled Error Pause 0xE1xx DIMM_x has been disabled. Any DIMMs which fail POST
Memory BIST will be disabled
prior to continuing POST
DIMMs installed in wrong DIMM
slot is disabled.
DIMM SPD Read Error Major 0xE7xx DIMM_xy Component
encountered a Serial Presence
Detection (SPD) fail error.
BIOS was unable to read DIMM
SPD data correctly. DIMM is
disabled.
Note: x is the instance number of the DIMM that failed.
