A few days ago I bought 4 sticks of kingston hyperx blu ddr3 ram. At the time I didnt realize that the voltage was a big deal. They run at 1.65v and the more I read the more I'm seeing that 1.5 is recommended. Tried to return them to newegg but decided not to because it would cost me around 25 bucks. Should I try selling them and buying 1.5 or will these be fine without messing up any of my other components? The cpu will be a i7 3930k on a gigabyte x79 up4 motherboard. Thanks.
