By default, HyperX have made their Predator DDR4 conform to the JEDEC 2400MHz CL17 standard, rather than 2133MHz CL15, do even if you do not go into the BIOS to enable the XMP setting, you will be sat at a higher frequency than what is commonly found, and you will of course have the peace of mind of a lifetime warranty backed by those awesome HyperX guys.
