This guide is for original haswell but the Devil Canyon Oc the same way just usually better oc.http://www.overclock.net/t/1411077/haswell-overclocking-guide-with-statistics
Dowload x264 "the cool stressor" from above front page. Use that for stability. Passing 20 loops is going to be very close to stable.
Try 4.8ghz 1.250. if it gets to the desktop run 2-3 loops x264. if your vcore way off it will crash fast.
If it fails push vcore to 1.275v repeat. If it fails again push vcore to 1.3v. If 4.8 1.3v does pass drop back 4.7 1.250v and work up to 1.3v again.
Leave everything else on auto except set cache to manual 4.2 1.2v and input voltage to 1.85v.
Hopefully you get the idea. These cpus do 4.5-4.9 ghz at 1.25-1.3v depending on silicon lottery (quality of cpu).Edited by Wirerat - 1/24/16 at 9:10am
