I agree with photonboy. I have the 8600K and all I had to do initially was the change the cpu core multiplyer to 47, leave eveything else in auto and it worked overclocking to 4.7GHZ. I then moved slowly up and have settled on a 4.9GHz overclock with an offset vcore with a max at 1.278v. I did set the LLC to high...On my motherboard the options for LLC are Auto, Medium, High and Turbo. Anyway.
