News Corsair Radically Expands 32GB DDR4 Desktop DIMM Availability

Nice! It would be nice to know if 4•16Gb or 2•32Gb is better option now for daysy chain motherboards...
Since nobody is "wasting" the higher-density chips on single-rank DIMMs, I'll assume both of those would be filled with dual-rank DIMMs. Some platforms get a small boost from having eight ranks rather than four, but it's not significant.
