>Will try 0x32 as a value after i submitted this mail. :)

You know what happend, the system froze and did not boot (stuck at C1).
It did boot after i removed one dimm. And on the board that dimm did no longer work.
I'm running this board with an other two dimm kit now, using the same slots as with the first kit.
I tried the defect dimm in the GBT780G board and it did not work. I tried the other dimm of 
that kit and it worked. Then i tried both and they work. 

So I went adventurous again. ;)

I know where to measure vdimm on the board.

>i2cget 0 0x2e 0x35 => 1,942V 
>i2cget 0 0x2e 0x36 => 1,916V
>i2cget 0 0x2e 0x37 => 1,892V

That is nice to know but seem to be no good for detection, every change changes the vdimm atleast at about 0.024V.

Also the sensor chip shows the difference, 

vddr = NB-HT voltage
in5 = SB voltage
in6 = vdimm
cpu0_vid seems to be the max cpu_vid.
