mixing ram Rules for mixing ram

[aRealCyborg]

What are the rules for mixing ram? so i have a Hyper X 8gb 3000mhz DDR4 ram and i want to get a RGB stick from hyper X can i do that.

do they have to be the same speed and same GB size and do they have to be the same timing and voltage?

what errors mite happen, will there be a chance that if they do work that they are more likely to stop working later by errors or what not.

They have to be the same memory type. You can't mix DDR4 with DDR3, and vice versa.

 

That's basically all there is to it, capacity doesn't matter, speed doesn't matter.

The motherboard will automatically default all RAM to match the speed of the slowest stick.

But can you mix RGB and non-RGB stick?

In theory that's true, but sometimes having different memory in the same channel can cause problems. Maybe that's not a thing anymore in new motherboards, but I've seen weird things on systems with mixed sticks.

Sure, the presence of RGB makes no difference whatsoever to the motherboard.

if i were to mix 2 different ram would i have to put them in different channels so no duel channel memory?

You will never get dual channel unless it's the same capacity. Additionally, the PC can altogether fail to post with mismatched ram, but that's not particularly common.
