General memory module installation guidelines
To ensure optimal performance of your system, observe the following general guidelines when configuring your system memory.
If your system's memory configurations fail to observe these guidelines, your system might not boot, stop responding during
memory configuration, or operate with reduced memory. This section provides information on the memory population rules and
about the non-uniform memory access (NUMA) for single or dual processor system.
The memory bus may operate at speeds of 3200 MT/s, 2933 MT/s, or 2666 MT/s depending on the following factors:
● System profile selected (for example, Performance Optimized, or Custom [can be run at high speed or lower])
