Help with overclocking Gigabyte Z87X-d3h

It's not a nightmare, you just have to do some research and ask lots of questions. You've already asked some questions, now you just have research and ask more, and then from there, take baby steps.... and research and ask more questions. Pretty soon, you'll be able to tell the bull from the facts.

As for deleting this thread... while you can't delete the responses, you can certainly delete yours. BUT.... you might as well leave it as this could turn out not only helping you, but others in your situation. Plus as you learn, you can always come back and input what you learned or didn't. It helps everyone involved.

Good luck.
