Notes:
1. DIMM configurations that support Sub NUMA Clustering (SNC), which can be enabled via UEFI. SNC is
not supported if DIMM population does not follow the sequence indicated by the table above.
2. DIMM configurations that support Software Guard Extensions (SGX). See "Enable Software Guard
Extensions (SGX)" in Setup Guide to enable this feature.
The following table shows the sequence of populating memory modules (with different capacities) for
independent mode when two processors (CPU 1 and CPU 2) are installed.
