Nevermind, I read your post the other way around. Sorry.

Ah, for some reason I thought that graph was at a constant frequency.

The first graph is at Manual voltage for the CPU. That just explains that when you load the CPU to 100% the voltage drops.

I must say, when I was OC'ing I just had to take a jumper on the MB and move it or go into BIOS and up the multiplier. I just got back into OC'ing and was lost by far but this posting by kevinxxxx and the one before took the new tech and actually explained it in a way my mind ( which has been out of the tech world for many years ) can understand it. So much so it prompted me to buy a gigabyte 990fxa-ud3 MB tonight for my old Phenom II X4 965 BE and see what I can do to this thing

Great. I hope it helps. I read that wall of text by shad0wfax over and over again until I completely understood it and it really makes sense.

I will post an explanation by shadowfax regarding this to backup these info. I just can't find it right now.

VID is a range of "allowed" voltage for the CPU to operate STOCK.

LLC overshoot fear origin was caused by this article:

This is where you quoted ultra long paragraph images come from.

Later they said LLC would unlikely kill your CPU and their article might went a bit too far. I can't find back this statement as it was probably on forums. Take it as you want. I let you the chance to browse more forums.

As I said, LLC will not kill your CPU, high voltage will. In 2007, VRM technology had less phases and were less precise. Now we have digital VRM and 6 - 8 phases is the norm for us overclockers.
Your source is outdated and your fear of LLC excessive. Of course, LLC can harm if you use crazy high voltage. Nobody has the exact answer, some say 1.5v LLC can be dangerous, I stop using extreme LLC with 1.45v (5.1GHz) and my CPU is still alive. Our guy only want 5GHz in this thread. He's not going to kill his CPU using any extreme value on his board beside a high voltage.

The thing that made me laugh was your statement on the power efficiency. Dude, using Vdroop is not going to make your CPU more efficient. lachen.gif

Take it as you want also.

Just try it, you would be surprised that an overclock of 4.7GHz with Medium LLC will produce better benchmark scores than an overclock of 4.8GHz with High LLC lachen.gif

Let's just forget about this discussion, I can't prove my point if the original poster of that info, shad0wfax, is already out of this forum for so long. He was a very helpful guy to the Sandy Bridge OC community.
