I have a custom loop with a 480mmx80mm rad, and everyhting buyt my RAM and SSD are watercooled, so I know cooling is not the issue. I have an Asus Rampage IV extreme MOBO, an i7-3930k, GTX 780, 8GB of ram @ 1600MHz, and a 760watt PSU, and even though I enable all of the bios settings that are supposed to help with overclocking, and keep increasing voltages, I can't seem to get it stable, does anyone know of what settings/voltages I should be specifically tweaking, or care to share the settings that they are using with the same MOBO?
