hi i am thinking about building a new pc and getting an i7 4930k and i am not sure whether to get 2133 mhz or 2400 mhz of ram. It will most likely be kingston hyper x with 16gb. and also what do you think is better 4 sticks of 4gb or 2 sticks of 8gb? thanks for the help. i think that the 4 sticks of 4 only use 1.2 volts and the 2 sticks of 8 produce 1.6 but i think i can find 2 sticks of 8 with 1.2 volts. thanks for the help.
