Ok, I getting desperate now ... somehow !
I just realized that all OC wonīt work as soon as I put my second RAM on.
These are my RAMs 
But I donīt have a clue why they wonīt want to be clocked.
As long as I have only one of them onboard ... everything is fine... but as soon as I put the second onboard I get one BSOD after the another.
It seems that no setting ( none that I tried ) effects my stability.
CPU : QX9650 - graphic 4870X2
My settings so far :
FSB : 400
CPU Clock Skew: Auto
NB Clock Skew: Auto
FSB Strap to North Bridge: AUTO
PCIE Frequency: 100
DRAM Frequency: 1600Mhz
DRAM Command Rate: auto
DRAM Timing Control: Manual ( 7-6-5-15- all the rest auto )
DRAM Static Read Control: disabled
DRAM Dynamic Write Control: disabled
DRAM Skew Control
DRAM CMD Skew on Channel A: Auto ( tried 50 delay )
DRAM CLK Skew on DIMM A1: Auto
DRAM CLK Skew on DIMM A2: Auto
DRAM CTL Skew on DIMM A1: Auto
DRAM CTL Skew on DIMM A2: Auto
DRAM CMD Skew on Channel B: Auto ( 100 delay )
DRAM CLK Skew on DIMM B1: Auto
DRAM CLK Skew on DIMM B2: Auto
DRAM CTL Skew on DIMM B1: Auto
DRAM CTL Skew on DIMM B2: Auto
Ai Clock Twister: auto
Ai Transaction Booster: Auto
( I tried with loosen PL and light Twister )
EPU II Phase Control: Auto
CPU Voltage: 1.27
Load-Line Calibration: Disabled
CPU PLL Voltage: 1.6
FSB Termination Voltage: 1.3
CPU GTLVerf (0): +50mv
CPU GTLVerf (1): +50mv
CPU GTLVerf (2): +50mv
CPU GTLVerf (3): +50mv
NB GTLVerf: +60mV
North Bridge Voltage: 1.51
DRAM Voltage: 1.86
NB DDRVref: auto
DDR3 ChannelA Vref: auto
DDR3 ChannelB Vref: auto
South Bridge 1.5 Voltage: 1.6
South Bridge 1.05 Voltage: 1.06
CPU Spread Spectrum: Disabled
PCIE Spread Spectrum: Disabled
I also played a lot with the GTLs ( cause I first thouht it would be the CPU )
I raised NB to 1,6V - no effect.
Temps are all in safe areas ... got a hughe wc.
So if anybody got a clue how I can use all of my 4GB Ram I would be more than pleased.

- The whole testing allready ruined my raid0 ... ( allthough in Memtest - with a good old floppy-disk - ran through without any error ! )
