Optimal memory config

I added some more memory  to a couple R710s and both are displaying at boot that they have a non-optimal configuration, although they still run.  Below is my current config, is there a way to use these chips so both boxes get 128GB?  If I need to buy more/different chips let me know.  I thought I was following the R710 memory configuration guides properly, but apparently not.
