Overclocking.guide is a website built and maintained by Der8auer with support content from other overclockers located around the globe. The goal of the website is to 1) void your warranty, and 2) help you figure out the overclocking settings of your hardware. You'll find guides on how to unlock power limits on Nvidia graphics cards, how to replace the GTX Titan X super-poor stock VRM with an external VRM, and much more.
Two weeks ago Der8auer published a guide on how to overclock the ASUS Maximus VI Extreme. Inside the article you will find all the tools needed to push the board (and your CPU) to the maximum. Der8auer also included a YouTube video in case you're at war with letters this week. You also find BIOS screenshots to help you overclock the latest Haswell K SKU processors from 3.5GHz to 4.3GHz. Oh, and if you don't know what those darn crazy terms used inside the BIOS mean, there's a helpful section with a basic rundown of the most important settings. All in all, well ... all you need.
