BIOS.MemSettings.NodeInterleave (Read or Write)
Description
When set to Enabled, memory interleaving is supported if a symmetric memory configuration is installed.
When set to Disabled, the system supports Non-Uniform Memory Access (NUMA) (asymmetric) memory
configurations. Operating Systems that are NUMA-aware understand the distribution of memory in a
particular system and can intelligently allocate memory in an optimal manner. Operating Systems that are
not NUMA aware could allocate memory to a processor that is not local resulting in a loss of performance.
Node Interleaving should only be enabled for Operating Systems that are not NUMA aware.
Only available if 2 or more CPUs are present.
