If you don't need insane amounts of memory, there's a DDR4-4000 64GB (8GB x8) kit with optimized CL15-16-16-36 timings. In order to run at the advertised speed with the aforementioned timings, the modules require 1.50V.
As with all high-end G.Skill memory kits, the ones announced today are built with hand-screened memory ICs and custom, 10-layer PCBs. They're also backed with G.Skill's limited lifetime warranty.
G.Skill didn't share pricing or a specific release date for the memory kits but said we can expect to see them on shelves sometime this quarter.
