G.Skill offers 128GB 3000 MT/s DDR4 kit for Intel X99 systems
 

G.Skill thinks that 64GB still isn't enough for a single memory kit, and it's now releasing a 128GB DDR4 kit targeted at Intel's X99 platform. Yes, one hundred and twenty-eight gigabytes, a figure larger than many SSDs. 16GB DIMM support for Haswell-E CPUs and X99 mobos isn't official, but at least one board maker has enabled it with a BIOS update, and it seems likely others will follow suit.
