so finally i think problem solved ! ...

after i flashed my bios with F9a
didn't changed any values ... and my system is running now above 55 hours and still no freeze or BSOD ... i'm gonna give it a few more hours till it reach 72 hours and then i could be quiet and happy...

forgot to mention ... in those hours i tested the system with occt and intelburntest(10runs) and the highest temp was 73 in one core...but my avrage temps in stress were around 60/63 if i remember corectly .

i just wanted to thank kick who try to help me and wish you all happy
holiday .
