Ok, so I have 16gb of RAM 2400mhz and a 10-12-12-31 timing. I know how to correctly change my RAM manually but would like to know if I must adjust my CPU settings to achieve the correct speeds. I have a core i5 4690k which I know is overclockable and a motherboard that has XMP. I don't want to overclock my CPU at all just because I don't want to shorten its lifespan and XMP i've heard is a crappy way to change the RAM settings. Any help would be great! Thanks
