ok, for cpu:
200BCLK
VTT 1,33V (200BCLK rock stable) but tested up to 1,45V
PLL 1,81V
PCH 1,08V
qpi 3600MHz (7200)
DRAM only up to 1,66-1,67V

cooling: water or SS -45° without any change...

for memory:
timing is from the XMP profil, after I was manual set TRFC and dividers...
for 2390MHz on ram is this setting OK, but 2400+ is impossible.
