Help text

This option is best suited for non-NUMA systems with flat address space. The FLATMEM is the most efficient system in terms of performance and resource consumption and it is the best option for smaller systems.

For systems that have holes in their physical address spaces and for features like NUMA and memory hotplug, choose "Sparse Memory".

If unsure, choose this option (Flat Memory) over any other.
