Probably ultra high? Which works for me.

Wow, the great info is coming in quick

So I keep hearing about LLC, but I'm wondering your guys' opinion on it: I read that LLC WITH offset voltage causes conflicts and voltage spikes... so should I keep it enabled it anyways when I move to offset? And it seems that my multiplier is locked at 45x and speedstep or turbo normalization are both not kicking in :S

Well I experienced voltage spikes without setting the LLC to ultra high with offset.
I hear different stories about LLC and each situation may differ. Asus z68 mobo goes well with
Ultra high in most situations according to the experience of alot of ppl.

So I found that my 2600k is pretty stable @ 4.5Ghz and 1.315v-1.320v, and I re-seated my hyper 212 and now my max temps are 67c

how would I get my PC to do all of this now with offset voltage instead of a fixed voltage?

If he can hit 45x, his goal~ then we can go to manual voltage. I didn't want him to overshoot or undershoot. If he can't do 45x on auto, then we wouldn't really have a good starting point, but you got him where I wanted him eventually anyway so it turned out ok. :3

There's a more precise science to doing what I did to get this to happen, someone might be more clear about exactly how this is done but I'll try to explain it in practical terms.

I use offset voltage, and it takes some trial and error. For me, what I did is I found out where I was most stable with manual voltage like you are now (which was 1.36 or so), then look at CPU-Z during LOAD on Prime95 to see where it was at when it was stable on load voltage wise.

So I set my voltage to +0.010 and saw my voltage was 1.39 or so in Prime95. It was stable, but more voltage than I wanted~ so I dropped it in 0.005 increments until my load voltage was where I wanted it to be. If It didn't boot into Windows, I'd up my LLC a notch which made my idle volts more stable. Every time you do this though, recheck your offsets.

I ended up actually only needing to set it to -0.005 to get to 1.35-1.36v on load, totally stable. These numbers are totally dependent on your VID, and vary from chip to chip, which is why I said it'll depend on trial and error. Like finding out where your center is, your zero~ then adding or subtracting with offset from there.

Maybe someone may help better with this.

Then change your multiplier to 45. Then come back. Make sure you have CPU-Z, Prime95 and Coretemp (or Realtemp) installed. Literally, that's all you're going to do. Change the multi, and then log into Windows.

You're overclocking one of the easiest processors in the world to OC. It's actually a little ridiculous.
Is the 2500K the same way?

Yes, but I'd recommend setting manual voltage once you figure out what your CPU can do.

I think you explained it sufficiently. It's somewhat complicated to explain even if you understand how it works. I like the new options in the new Intel motherboards. Much better than a couple years ago where you always had massive vdroop and had to mod the boards in some cases to get them to quit it. Now you can account for this through some bios settings to get almost the exact vcore you need.

Ok mate makes sense. It is indeed a matter of error and trial.
I ended up with a negative offset of 0.03 in order to get my
stable vcore. So as stated every situation is different.

He is on his way

Hmm this only seems to get more confusing

So I now have the following options:

Multi (by core, non adjustable in OS): 45x
PLL: Auto
Phase: Extreme
VRM: Auto
LLC: "Regular lvl 1" = 0%
Offset: +.05
max temp: 68c

and now my computer seems to be running stable @ 4.5ghz (was getting BSOD before when LLC was turned on auto...)

So now my CPU-Z shows max core voltage of 1.304 when using prime95, going down to 1.288 randomly. But my VID is showing 1.3761. Are these settings perfect the way they are, or is 1.3761 what my CPU is being fed?
