To start off I am a relative beginner when it comes to overclocking. I am used to basic overclocking on previous boards like the Gigabyte z77x-ud5P where you adjust the core speed and the Bios took care of the rest. I used to get up to 5.1GHZ on that UD5P. I just recently built a new computer with the Rampage 4 Extreme with an Intel 4930K with 64Gb Crucial Memory and a Corsair H150 Water Cooler. I did see another post like this, however it looked like his issue was overheating. On my computer the second my frequency goes beyond 4.7 My computer shuts off and restarts. So if I try to set the core to 4.8 It will load until the login screen then the second I click anything it shuts off. By another scenario if I set the cores to 4.6 and allow them to go up to 4.9, when a core goes over 4.7 it shuts down and restarts. Now I've never dealt with voltage and the other parts of overclocking. I know that at 4.7 I am running a temp of around 34 degrees C so I feel that overheating is not an issue. I figured it might be memory or voltage related. Can anyone offer up their wisdom? Thanks
