So I'm stable at 4.6ghz on my 6600k. The only problem is I have to get close to 1.4V to get there. I'm just not understanding my voltages though. If I set my BIOS voltage to say 1.4, when I bench, it only gets up to about 1.370 or something. It never actually gets to what my BIOS is set to. But when I stop the stress test or bench, the voltage goes right up to my 1.4 V (or whatever it's set to). My voltage also does not drop down when CPU not under stress. Voltage is set to adaptive. Heat is not my issue at all. I could probably run this thing at 1.450 V without over temping. I just don't like how high my voltages are getting, and the fact that they aren't dropping at idle.
