I hope this isn't a stupid question. I am going to build my first computer with a Gigabyte mo/bo that will support 32GB's of RAM. Before I make the initial start of the computer upon completion, can I install 2 8GB modules of RAM, and leave the other 2 slots empty? I am asking this because eventually I will add more SSD's and more RAM and I don't want to fill the 4 RAM slots with smaller capacity modules and then later have to buy all new modules with greater capacity. Thanks for any advice on this subject!
