I happen to have 2x4GB (ddr4-2400) rams from a previous system, and I also bought 2x8gb ram (ddr4-2400 as well). I was wondering if I put all 4 in my motherboard, would I be able to use 24 gigs of RAM? All 4 rams are from the same manufacturer and have same timings. Also, if yes, what sequence should I put them in?
