i build anew pc with amd 4300 and msi 970a g43 with 8gb ddr3 hyperx fury 1866mhz. Graphics card is asus gtx 780.
now the problem is pc starts and i open bios and it shows my 8gb ram with 1866mhz but not more than 20 - 60 secs and screen freezes .
and if i put my old 2gb ddr3 1333mhz ram every thing works fine.
also if i cobine these two rams then it shows 10 gb ram and in windows it shows 1.95 usable.
with single 8gb stick it stucks i dont know why.
when all the specs are currect.
