My motherboard can support up to 3100 MHz ram, so I fine in that department. What I wondering is if it matters if I exceed the ram speed limit on my CPU. If I were to buy 2400 MHz ram, would it just only use the ram up to 1600 MHz and just be a waste of my money for buying better ram, or will it actually use all of the ram and I would benefit from it. Please help, I've been looking everywhere for an answer for this and I can't find one. Thanks
