[SOLVED] Is 2666MHz works on 2667MHz if you will mix it I have acer nitro 5 and it supports 2667MHz does it support 2666MHZ

Solution
Those are the same thing. However, mixing memory is always a gamble. Sometimes mixed memory will work, often it will not. Using a matched set of memory modules that came TOGETHER is the only way to guarantee that all sticks will play nice together.
