I currently own a Gigabyte Z97-D3H. It is upgraded from my GA-H61M-S2PV. On my previous motherboard, I had 2 sticks of 2GB of RAM, totaling 4GB. I currently have 8GB on this motherboard. Because the MoBo features dual channel mode, I was wondering if I could have my stick of 8 by itself in one channel and the two 2s running together to total 12GB?
