Hello, i ve bought Kingstom 8GB KIT DDR4 2133MHz CL14 HyperX Fury Black Series (Dual-channel) 2 years ago. I want to upgrade my RAM. I want to buy 4 GB more, but i cant find CL14 timing anywhere on the internet (in my country). My question is : Can i combine CL14 8GB with 4GB CL 16 ? Thanks for your answers.
