Figure 11. Memory Settings Node Interleaving Specifies if Non-Uniform Memory Architecture (NUMA) is supported. If this field is set to Enabled, memory interleaving is supported if a symmetric memory configuration is installed. If the field is set to Disabled, the system supports NUMA (asymmetric) memory configurations. This option is set to Disabled by default. Node interleaving is not supported when NVDMM-N is present in the system. WARNING: When Persistent Memory Interleaving is enabled in the Persistent Memory System Setup page, Node Interleaving setting also applies to Persistent Memory Interleaving. Select Persistent Memory to configure NVDIMM-N setup options: Persistent Memory Scrubbing Set Persistent Memory Scrubbing mode. Auto: System automatically scrubs persistent memory during POST when multibit errors have been detected. One Shot: System will scrub persistent memory during POST on the entire persistent memory range once. Upon next boot, system will go back to "Auto" persistent memory scrub mode. Enable: System will scrub persistent memory during POST on the entire persistent memory range on everyboot. NOTE: Scrubbing persistent memory on the entire persistent memory range could take more than 60 minutes during system POST depending on system memory population. BIOS 19

Node Interleaving
Specifies if Non-Uniform Memory Architecture (NUMA) is supported. If this field is set to Enabled, memory
interleaving is supported if a symmetric memory configuration is installed. If the field is set to Disabled, the system
supports NUMA (asymmetric) memory configurations. This option is set to Disabled by default. Node interleaving
is not supported when NVDMM-N is present in the system.
WARNING:
When Persistent Memory Interleaving is enabled in the Persistent Memory System
Setup page, Node Interleaving setting also applies to Persistent Memory Interleaving.
Select Persistent Memory to configure NVDIMM-N setup options:

Auto: System automatically scrubs persistent memory during POST when multibit errors have been detected.
One Shot: System will scrub persistent memory during POST on the entire persistent memory range once. Upon
next boot, system will go back to “Auto“ persistent memory scrub mode.
Enable: System will scrub persistent memory during POST on the entire persistent memory range on everyboot.
