So I'm upgrading my memory of 8GB of rams up to 32GB of it. I have a MSI 970 AM3+ Gaming Motherboard. I only have one ram stick, a Kingston Hyper X Fury 8GB 1600mhz blue. I know this is a dumb question but my plan is to buy three of this kind of ram stick but with different colors like the red, black, and white. Is it okay to buy three different colors but I will buy the same specs such as 8GB and 1600mhz. Thanks.
