System Memory
Voltage
Displays the system memory voltage.
Video Memory Displays the amount of video memory.
System Memory
Testing
Species whether system memory tests are run during system boot. Options are Enabled and Disabled. By
default, the System Memory Testing option is set to Disabled.
Memory Operating
Mode
Species the memory operating mode. The options available are Optimizer Mode, Advanced ECC Mode, Mirror
Mode, Spare Mode, Spare with Advanced ECC Mode, and Dell Fault Resilient Mode. By default, the Memory
Operating Mode option is set to Optimizer Mode.
NOTE: The Memory Operating Mode can have dierent defaults and available options based on the
memory conguration of your system.
NOTE: The Dell Fault Resilient Mode establishes an area of memory that is fault resilient. This mode
can be used by an operating system that supports the feature to load critical applications or enables the
operating system kernel to maximize system availability.
Node Interleaving If this eld is Enabled, memory interleaving is supported if a symmetric memory conguration is installed. If
Disabled, the system supports Non-Uniform Memory architecture (NUMA) (asymmetric) memory congurations.
By default, Node Interleaving option is set to Disabled.
Serial Debug Output By default, it is set to disabled.
