When the PPC440 option in the MIG tool is selected it limits the supported memory interface data widths to 16, 32 64 bit, and 72-bit with ECC.
When PPC440 is selected, it limits RDIMMs only for 72-bit data widths and components, UDIMM and SODIMM can be used for the other non-ECC data widths.
This is a limitation when selecting PPC440 rather than a limitation in the MIG GUI.
As a result, when you deselect PPC440 the 72 bit option becomes available.
