What is
1. QPI VTT control?

You need more granularity? The granularity is dependant on the VID table support of the buck controller so what you have now is likely all that can be given.

As for the other two I will ask - that is all I needed.

First thing first, zoson is right, I meant QPI PLL, I am just very tired, so I made a mistake.

Second, we are making a progress we haven't seen in a long time. You just made some things clearer. Nobody took the time and effort until now to give an explanation.
Everybody thought (as zoson and me of course) that QPI PLL is linked to CPU PLL and you are saying that it is not. Please explain us to what is it linked to, if anything.
I could also assume it just might be fixed to default 1.1V and uncontrollable, but that might be wrong as assumption that it's linked to CPU PLL.
So, you get my point? Any answer is a good answer. If we know how things work, we'll make the best of it.

Third, and back to the beginning of your post... diatribe...
I didn't even knew what that means, as English is not my mother language. When I looked in the dictionary I was very disappointed at first, cause you see my criticism in the wrong way.
Look around and find my posts, then judge if my posts are bitter or ironical or non-constructive.
But, for the sake of good relations and constructive talk, I'll just accept that as your subjective experience of my post, and I'll try to be more careful how my posts sound like.
