So at the website of my motherboard, http://www.asrock.com/mb/Intel/Z170%20Extreme4/
You can see that it says it supports DDR4 3866+ OC Modules. My question is what does this mean, exactly? Is that the minimum amount of Mhz that it supports? I have a ddr4 ram stick which is 2666Mhz. Do I have to buy another one for my system to work properly? Because as of now my system will shut down on its own every 10 seconds when the ram stick is on the motherboard. When I take it out, I just get 3 beeps but the system stays on.
