Well I sit today with 2x2GB DDR3 memories. But my local computer store, have the same memories of an extremely low price, so I'm looking to buy 2x2GB for (so I get 8gb). To my question: I've always just run with two sticks, then there would be four sticks. Will I have problems (due to my overclock) Viz that i need to raise the various voltage values to get the CPU stable with 4 sticks? Appreciate the response from people with experience in this ONLY! Thanks in advance.
