Have you tried the RAM in both pairs of colour-matched slots?

@philip corcoran already tried sir, i put the ram in colour-matched slot (A1/B1) or (A2/B2), still freeze , especially when pc under load , but running with no problem if i put the ram in A1/A2, or B1/B2 (different color), raises ram voltage to 1.6v, still freeze in same color. oh ya, if i put the ram in colour-matched slot (A2/B2 or A1/B1 - dual channel) then my pc freeze, when i hard reset the pc and go to bios, only 1 stick of ram detected, but oc tweaker detect the ram in both slot
