I bought 16gb dual-channel memory (G.skill sniper), it's supposed to run at 1866 and my motherboard (asrock 990fx extreme3) is supposed to be able to handle that speed. So how can i make it run at 1866? i know it's an extremely small difference but i want to get the most of my investment, i wanna get exactly what i paid for. I am patiently waiting for your answers. Thanks in advance!
