Corsair today launched a new group of Vengeance LPX modules based on 16Gb (2GB) ICs, making capacities from 1x 32GB to 8x 32GB (256GB) available to anyone with the firmware to support it. The use of higher-density chips enables these to be organized in an industry-standard eight-chip-per-side layout, making them electrically compatible with the widest-possible range of DDR4-equipped consumer motherboards (unlike some double-capacity DIMMs that organized two modules on a single PCB).

XMP Data rates are quite limited, considering the recent release of non-XMP DDR4-3200, but that’s to be expected with higher-density, lower-volume silicon. We have no word yet on whether the modules use Samsung’s new A-Die or Micron’s new D9XPF, but it’s nice to finally see availability that extends beyond the almost-mythical Samsung OEM. Currently available at Corsair’s store, several of these kits are also available for pre-order at other online retailers.

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.
