I have my eyes on this motherboard Asus M5A78L-M/USB3 AMD 760G (Socket AM3+) for fx6300 processor what makes me confuse the specifications says that the motherboard supports upto 16gb ram this means 2x8gb ram can be supported but i have only two dual stick of 4gb and they are running at 1333mhz. So my question is will this motherboard support my dual 4gb ram or i have to buy a single 8gb ram.
