The Vengeance SODIMM DDR4 4000 32GB (4x8GB) is a record breaker, Corsair says-- aimed at high-performance gaming machines and boasting "super-tight CL19-23-23-45 timings at 1.35V."
The memory kits require DDR4 SODIMMs, and are designed for use on the high-end desktop Intel X299 motherboard platform in SFF and mini-ITX form factor. The 32GB kit comes in four 8GB modules built on eight-layer PCB, and Corsair says it is made using hand-sorted and extensively binned Samsung B-die ICs memory chips.
A Corsair test has the memory kits validated using an ASRock X299-ITX/AC motherboard and an Intel Core i7-7820X Skylake-X processor. They are XMP 2.0 compatible, allowing for both easy installation and overclocking without need to enter the BIOS.
The Vengeance memory kits should start shipping soon.
