My system at the moment consists of AMD FX6100 - ASUS SABERTOOTH 990FX -8GB KINGSTON DDR3 1600 ram, all running stock speeds. Is it possible to change to a higher rated ram such as Crucial Ballistix Elite, this ram I believe runs at 1.5v. The question is would it be safe to use at this voltage and would the m/board automatically adjust to suit.
