The weird thing is, I tested it first with memtest as a quick test 10 passes for test #5, then primed it 8 hours with prime blend, it was stable so far, I just got now my rig like 2 weeks in that 2 weeks It just happend 2 times suddently reboot. So today I was suspecting perhaps the ram, So yes I did some memtest #5 now it would crap out very soon , setted the subtimings to auto instead still bad luck and even downclocked the fsb with 3 notch still no luck:X very odd:X
