Right now G.SKILL is pretty much alone in bringing 8GB DIMMs to speeds above DDR4-3733. They already have a 2x8GB kit in the DDR4-4000 and DDR4-4133 ranges, but they’re now introducing a 4x8GB kit into the DDR4-3866 classification. The chip is rated at CL18-19-19-39 when supplied with 1.35V. This is much higher voltage than slower sticks, but, with a pretty good speed. It also supports XMP 2.0 to automatically configure your BIOS, which make life much easier for many of us.
While there are not that many situations where four channels of high-bandwidth memory will give you any real benefits, apart overclocking record categories. Oh for work there is high-end video editing of 4K and 8K footage and high-end CAD work does come to min.
Pricing has not yet been announced. That said, a 2x8GB DDR4-4000 (the next category up) of the same brand can be found for around $190 USD. 2x8GB DDR4-4133 (the next category above that) is about $220 USD. While those kits contain half the sticks, 2 vs 4.
