Memory Operating Mode
Description
NOTE:
To use memory sparing, this feature must be
enabled in the BIOS menu of System Setup.
NOTE:
Memory sparing does not offer protection against
a multi-bit uncorrectable error.
Dell Fault Resilient Mode
The
Dell Fault Resilient Mode
if enabled, the BIOS creates
an area of memory that is fault resilient. This mode can be
used by an OS that supports the feature to load critical
applications or enables the OS kernel to maximize system
availability.
NOTE:
This feature is only supported in Gold and Platinum
Intel processors.
NOTE:
Memory configuration has to be of same size
DIMM, speed, and rank.
Optimizer Mode
This mode supports Single Device Data Correction (SDDC) only for memory modules that use x4 device width. It does not
impose any specific slot population requirements.
●
Dual processor: Populate the slots in round robin sequence starting with processor 1.
NOTE:
Processor 1 and processor 2 population should match.
