16GB DDR3 un-buffered memory modules were planned but with the introduction of DDR4 un-buffered memory it appears memory manufacturers abandoned that idea as no such modules were ever introduced to the market. You can buy 16GB un-buffered DDR4 modules.

DDR4 was released to the market in 2014. The transition from DDR3 to DDR4 is taking longer than the approximately five years taken for DDR3 to achieve mass market transition over DDR2. Don't expect 16GB un-buffered DDR3 to take place as there is little interest or demand for it today.
