Thanks for the reply. Unfortunately, I'm limited to 2400 by my motherboard (MSI B250 Pro-VD) and don't really want to upgrade. Am still running LGA1151 and an i7 6700k not overclocked. IMO still respectable performance out of my CPU. Since the theoretical limit is 2400, it would not be an improvement worth the whole new set, would it? Linus video on the topic is fairly old, so what really are the performance losses?

I'm still running 8GB of DDR4 2133mhz and since its affecting my performance in multitasking and in games, I want to upgrade. I currently have one stick of Crucial CT8G4DFS8213.C8FDD1. It's not available anymore and I don't want to spend twice the price for a whole new set of 16GB. Are ram sticks with the same speed and capacity but different brand compatible and what performance loss is there to expect? If they are not compatible, is there a chance of finding different ram from a different brand that is compatible?
