Recently i've assembled a configuration. Everything was fine, but when i booted the pc, the bios showed that the RAM (Corsair Vengeance 1600mhz) is running at 1333 mhz then i've turned on D.O.C.P and manually changed the speed to 1600mhz. But still at bios startup it shows memory speed 1333mhz and in advanced mode says Memory Expected Speed 1600mhz and in Task Manager it says 1333mhz ? So i dont know in what speed my memory is runing at..
