What about this one?

I think the main problem to run high RAM frequency is strictly related to uncore frequency and quality of IMC of CPU. There are a lot of RAM in the market that are able to run at high frequencies with really low voltages (all the kits equipped with elpida BBSE).

I won't trust this one for 24/7 use, either the stability (because you have tested the RAM all the way, at least on this screen shot) or the reliability/durability (because your are using VVT>1.35v). But yes you are right, when you get to high speeds (around 2000MHZ) then IMC plays much bigger role than it plays around 1700MZ. You need good CPU-batch to run Uncore >4200MHZ.

I know some sticks can run >1600MHZ, but most of these who are reporting about problems here, are running those "god old first generation 1600MHZ" RAM.

In fact now i'm stable at 200x18 with uncore 2800mhz with 1.24v (the lowest vtt, my mobo has a positive drop of 0,03v)

Ok, i don't really care about the uncore, but 'cause of this mobo i can't get my pc stable with ram >1400 mhz

Maybe your RAM (or CPU or other settings which i don't know much about) are limiting your MB? Uncore is sitting in your CPU, and is more dependent on your CPU-batch than your MB. In these speeds will the MB has almost nothing to say about your Uncore speed.
