4GB Kingston HyperX FURY DDR4 2666MHz PC4-21300 CL15 1.2v Non-ECC Memory Module by Kingston

Automatic overclocking up to 2666MHz.
HyperX® FURY DDR4 automatically recognizes the platform it’s plugged into and automatically overclocks to the highest frequency published, up to 2666MHz, for hassle-free, plug-and-play functionality. It delivers automatic top-level performance for motherboards featuring Intel’s 200 series and X99 chipsets and complements Intel’s 2, 4, 6, 8 and 10-core processors for faster video editing, 3D rendering, gaming and AI processing.

Available in speeds from 2133MHz–26666MHz, CL14–16 latencies and capacities of 4GB, 8GB and 16GB single modules and 8GB–64GB kits, HyperX FURY DDR4 is a minimal investment in premium components that results in faster speeds, higher performance and enhanced reliability — plus it looks really cool. It stays cool, too, thanks to 1.2V power consumption resulting in less heat, with a lower voltage specification than DDR3. Its stylish, low-profile design complements the look of the latest PC hardware while helping you stand out from the crowd of squared designs.
