Hi, a few days ago I ordered Corsair Vengeance Pro RGB that's 3200mhz and 16gb (2 sticks). In the mail I got the same memory just at different speeds and capacity. It is 32gb @2666mhz. I'm wondering if I should return it for the original since I have a Ryzen CPU that benefits from fast memory but I could just add it to my already 16gb of ram that runs at 2666mhz. Any thoughts?
