Did I mension that my SECOND chip died too?....
Worked in dual channel with the LN2 pot on the cpu filled with water (no LN2) - so acctualy the cpu on air) for some tests.....
It worked at ~800MHz with Cas 7-7-6-20 at ONLY 1.65Volts REAL....
After some testings/reboots, the mobo didn't powered up again...
Tested each one of the sticks, I found out that my second stick was dead too....
So TWO out of three sticks are dead...
