Hi folks. I have a few questions. I'm trying to overclock my 2600K to 4.8GHz on a Gigabyte P67A-UD7-B3. The new F4 BIOS for the UD7 now has 10 multi-step levels of LLC and I'm pretty confused as I'm used to off/auto/level 1/level 2. I can get it Prime95 Blend stable for 6 hours (longest I'm willing to stress it) but the voltage dances all over the place. I have 1.385 vcore set in the BIOS and LLC level 6. According to CPU-Z v1.58 at idle it's anywhere between 1.392 and 1.404. When stressing it can go anywhere between 1.356 and 1.392. Is this right??? Any input folks will be greatly appreciated.

Between 1.356v and 1.392v fluctuation under load seems a hell of a lot, especially for a top end mobo.
I use a vcore offset which gives 1.32v load 90% of the time when stressing with P95 or LinX.
Occasionally it will drop to 1.312v or go up to 1.328v.
Just drooled on my keyboard when I saw the GPU's in your sig

Think I've sorted it, but it's pretty weird... I set vcore at 1.355 and load line calibration to level 6 and at idle it gives me 1.368v and when stressing it sits anywhere between 1.344 and 1.368. Ran Prime95 blend for 8 hours with no errors or warnings and max temp was 73 degrees. I'm pretty pleased, I seem to be getting there.
LLC 6 and LLC 7 are best for the UD7, UD5 boards. You have got that spot on. You get pretty much exactly what you have set in bios during load too.
The thing to remember is the volt drop as such is built into the desgin of Intel CPU's
