I was recently told that i5 ivy bridge's do not utilize any ram speeds above 1333, is this an accurate statement? I have my 1866 ram oc'd to 2100, and I'm being told it's not even being used. I have tried to research this with no luck. I monitor my pc during heavy tasks and see that it is using up the majority of my ram, but this info is not good enough as proof. Please help me understand whether this is true or not.
