So I'm getting a new motherboard and along with it, I want to upgrade my RAM. Is it possible that I buy 3 sticks of 4GB RAM seperately, for a total of 12GB, or even mix 4x4GB or 2x8GB for a total of 16GB? If I do mix, the RAM Sticks are gonna be exactly the same model but I'm not gonna get them in a bundle together, I'm gonna buy em seperately. Is this possible given my motherboards has 4 slots and supports up to 32GB?
