So. I have an asus z77 sabertooth mobo. I am running an i7 3770k. I know that my CPU can only run RAM at 1600mhz without overclocking, but in my BIOS it says my RAM is only operating at 1333mhz. I was just wondering if anyone could give me an idea of how to get my RAM running at 1600mhz. Any help would be greatly appreciated. Thanks in advance folks!
