What's bothering me and preventing me from gaining a full understanding of this power delivery system Intel designed is that I just don't know what the hell these options really DO from a control theory perspective. I don't really physically know how LLC works, I just know what people say happens when you use it, and it eliminates vdroop. I guess I need to start with getting a full understanding of what vdroop does past "helps reduce voltage spike under load"... which is the barest of bare minimum explanations you can give.

LLC could be doing a number of things, and without knowing what its true technical purpose is, I can't really say much. All I know is its supposed to help with Vdroop.

It's pretty funny how I read an article here: http://hardforum.com/showthread.php?t=1578110 from an ASUS tech rep and in his guide he essentially indicates that they used trial and error for testing various overclocking methods. So even ASUS doesn't really know what these options do? lol?

Maybe I'm making it more complicated than it needs to be, but I feel like an 8 year old kid pushing random buttons trying to see what makes the light go green.... and this is after reading tons and tons of articles. By now all I know is what's probably going to work, but I have such a minimal physical understanding that it's hard to say I know more than "jack *****".

It's probably my fault though. I'm more than likely looking for information in the wrong places.
I completely agree with what you said. Even the experts that actually know how some of these features are implemented seem to contradict themselves on a number of topics. I think the fundamental problem is that each chip/motherboard is just slightly different enough to cause unexpected and inconsistent results. It doesn't help that a lot of practices have changed since Sandy Bridge came out.

Also, thanks for the tip on C states, I put them back to auto. Many of the guides I found had them disabled. Go figure

railfain884, what do you think about posts like this:

"As you go higher in clocks without LLC, you are risking your CPU gets killed by unwanted voltage spike.That is what LLC is for. To protect your CPU. Made by your motherboard company. So turning LLC ON to some degree is highly recommended. Unless you are trying for risky 5.4GHz+ Bench run or something that requires absolute stability over risking your CPU to get damaged."

For every post suggestion that LLC be disabled there is a post saying it should be enabled for Sandy Bridge. Not too sure what to make of it.
