You seem to be taking things out of your hat.
I doubt you even know how a CPU works if you can say that.

Voltage has nothing to do with the processor performance beside one thing: the cpus stability. It is possible to have a lower benchmark score if the voltage used was too low.

I know now where you took that whole efficiency thing. The very same article talking about possible overshoot due to LLC:
http://www.anandtech.com/show/2404/6

It appears using LLC causes the system to be less efficient looking at this image:


Hu ho, let's read a bit more:

Finally, let's take one last real-world look at the consequences of removing Vdroop. ASUS' implementation of this feature, labeled as Load Line Calibration and included with their latest line of motherboards, is particularly worthy of our attention for a number of reasons. The first is that setting lower voltages with this option enabled actually results in a condition in which the CPU voltage under load is higher than the idle voltage. Imagine our confusion as we desperately struggle to understand why our system is Prime95 stable for days yet continues to crash under absolutely no load. What's more, in spite of the absence of droop and for reasons unknown, enabling this feature artificially raises our CPU's minimum stable core voltage at 4.0GHz from 1.28V to about 1.33V. As a result, our system uses more power under load than is otherwise necessary. Our efforts to reduce our processor's supply voltage backfired - instead of lowering the system's total power consumption we managed to affect a 20W increase.

The 20W difference is due because their load voltage is higher with LLC than without.

"Let's forget about this discussion."

Just admit you were wrong. We all do mistake and this article was not one of their best. The image is quite confusing because they do not precise the load voltage used.

Let me precise that this article is date from 2007, the very first time LLC appeared. Now we can control it and adjust precisely the voltage we need to run at. We won't be in the situation of using extra voltage we don't need.

soooooooooooooo


what settings to i want to be using?!

The answer is already in the thread. Check a guide to overclock with P67 asus board if you are not confident. There is no magic answer. Confidence will come with knowledge. Learn the function of settings and when to change or use them. When I received my z77 I spent 1 day to learn all I needed to know about it. If you want to push to limit, this is what you have to do.

LLC is fine to use, high voltage is not. It is also true LLC generate a voltage spike so it is safe to say under 1.4v LLC is fine.
I would personally not use more than 1.4v daily some say 1.38v is the max safe, nobody really know.

One of my friends has ran 2500K at 5GHz with 1.52V from BIOS for over a year now since he got it, no sign of degradation yet atleast, same goes for my 2500K which has been at near 1.5V for the whole time that I have had it (slightly over a year).

So considering that, I think 1.4V is more than safe, I would say anything below 1.5V is completely safe even.

Huh? I told you I got that whole wall of text from shad0wfax. I was not inventing and did not get it from any forum. He was the one explaining all that stuff and I just shared it here. I won't admit I am wrong because I told at the very first that I got that information from shad0wfax which really makes sense from all the concepts I've learned from school while taking up my course.

I don't get you. You say you are FOR LLC. Then the post you just made says using LLC increases the load voltage needed than without it. So in that sense, without LLC is better, which was exactly my point?

That was a while back, now we can precisely adjust load voltage with LLC.

As for saying if you were wrong, you are spreading assumptions that are not backed by anything but a name and a source that does not seem to be anywhere close to be official.

Also, I was not able to find anything about that whole concept of higher efficiency beside the link from Anandtech showing the picture I linked.

Take it as you want, believe what you want but if you take a single source as being truth holder, you might want to check twice if that is really true.
I tried to believe what you say was right and I found nothing. Yea, I checked for you.

Be sure your source is correct before using it. Friendly advice, nothing more.

Ok, I understand. Thanks for the info. I just didn't like your first approach on this, you could've said it better and I would've willingly accepted all of your explanations, you know.

In that case, then you are saying that is it better to set LLC to Extreme (100%)?
post #48 of 114
To push to the limit, yes. Daily use, no.

I used 1.45v-1.5v extreme LLC and others reported using much higher voltage with LLC. I think it is relatively safe using LLC. Relatively because I would not do it every day. On the long term, these voltage spike might cause so sort of degradation.

There is no definitive answer. If you don't feel confident using extreme LLC then don't. I personally find it helps a lot overclocking and I use standard LLC daily use (I think it is the equivalent of 10%-25%).

In that case, if you are using standard LLC then your BIOS-set voltage is really high? And of course your idle voltage will also be much higher than what is actually needed. This is, of course, if you are using Offset voltage.
post #50 of 114
Oh that is for my daily use I am using standard. At 4.2GHz I need 1.185v and my offset was at -0.085v using LLC set on medium resulted in crash when going full idle as the voltage was going down in the 0.5v range even though it was doing perfectly fine at load voltage. Increasing offset to -0.06v with standard LLC to maintain the 1.18v load resulted in 0.68v full idle voltage and 1.185v so I am quite happy with that.

I am new to the offset voltage world as a previous P55 owner.

I will eventually aim for 4.7-4.8GHz with HT as my gaming profile when I will have more time to spend on games smile.gif
4.2GHz is overkill for web-surfing and browsing biggrin.gif

When I pushed the box to 5.2GHz, the settings were all aggressive, nearly everything set to extreme. 1.5v (LLC kick-in) was way too much for me anyway, I saw what the CPU was capable and I decided to stop there. 4.8GHz is really the wall for sandy, past that and voltage increase is non-linear. If I remember, 1.34-5v was enough for 4.8, 1.4v for 5GHz and .1v just for a 200MHz gain (5.2GHz).
