I decided to up my OC on my i7 2600k from 4.6GHz to 4.8GHz, so I went into BIOS and changed the multiplier and started testing voltages with manual voltage to get an idea of the correct amount of voltage. I found that the best was about 1.344 in CPU-Z (which was 1.345v in BIOS, with Ultra LLC and standard Phase control). I'd prefer having offset voltage so that my voltage lowers on idle, so I changed it to offset and started testing to find my proper voltage but it seems the computer will only boot with a load voltage of 1.376v or more reading in CPU-Z, anything else and windows won't boot it BSODs at login screen (the offset I have is +0.015v with same settings as manual voltage, Ultra LLC and standard phase control).

Why does offset require that much more voltage than manual does?

Lower LLC and raise offset accordingly. This will raise the voltage the CPU gets at light/medium load because of vdroop. I had this same issue on my 3930k. I'm actually using LLC on regular and it works great.

Just use LLC on high or lower

Did you test for stability at 1.344 volts? (12-24 hours of Prime95 using all available ram?)

If it is truly stable at 1.344 volts then ensure that at full load, you are hitting 1.344 volts with your offset. Disabling C-states (C3/C6) may also help with stability. It certainly did with my offset overclock.

Alright so I did manage to get 1.344v under load with offset voltage and high LLC and I also disabled C3 and C6 states but after 30s of Prime95 it BSOD'd so I'm going to add a bit more voltage and see what happens.

EDIT: Lowering the LLC means I have to increase the offset right?, so if I lower LLC to normal my + offset would have to be higher?

Ok so I added 0.05v and am running Prime95 now, CPU-Z shows voltage jumping around from 1.336 to 1.344 to (not very often) 1.352 but seems much more stable then before, but is really around the same voltage as before...weird..

If you're seeing errors 30 minutes in, your overclock is far from stable. You should have tested for maximum stability with manual voltage first but to answer your question. Yes, the lower your load line calibration the more voltage droop there will be.

It's what Scorpion said, if you have too high a setting for LLC then you end up with too low an offset (because of LLC adding voltage under load) and you get crashes in lightly loaded situations. For offset you generally want as low a setting for LLC as you can get away with and a higher offset to get the load voltage you want - whatever medium is on your board (they have different names/values) is a good start. It's always a good idea to test your system using a single thread of Prime95 once you get the offset in, just to make sure it is stable in that situation.

Ok so I've got it at full load to be 1.360v and ran Prime95 for 45 mins or so and nothing went wrong, gonna put it on for longer tomorrow when i got more time (I like to be watching it while I'm stress testing it so not leaving it overnight) and I will see how well this stands up for me. Thanks for your help everyone and goodnight.

Messing with LLC has always been a shot in the dark. You need to get your voltages stable first without going beyond 1.4v at any time. I know the 2600K can handle 1.5v for short periods of time or longer if you dont mind having your chip life degrade faster. Try increasing your offset until you get a stable boot first, run your stess test, and then mess with PLL if you want. But keep in mind, if you turn off CStates, you will be running hotter even under idle conditions.
