Well thanks for the reply Ket.
I am not overclocking so SB/NB/CPU undervoltage and FSB strap applies to me also???
Ram Voltage and timings are Set manually because (again) auto recognized them as lower.I have teamgroup TXDD2048m800hc4dc-d so i have set them to 2.0V and timings 4-4-4-12 .....everything else auto....the problematic was not affected after changing these even when i removed 1 stick.
Any idea to check "flacky" PSU?
Probably i have to wait for 1501 bios....
Has anyone else encountered such a problem??
