Did you find a specification for NEC ECO CENTER in English?
I couldn't.
If, like Supermicro 6015C-MTB, it is based on San Clemente chipset then Blackford/Seaburg based experience with regard to which memory is faster could not apply. It's possible that a couple of dual-rank DIMMs is the fastest memory option for that chipset.
