Hey guys, I've spent hours over the last few weeks reading up on PC building, as I'm taking it up as a new hobby for gaming. After all my research, I'm still unclear as I've received mixed answers regarding ram. First off it is my understanding that each stick of ram will run at the speed of the lowest speed stick. However, can I use 1 stick of 1 gig ram and another stick of 2 gig ram to give me 3 gig ram? Or mush they all be sticks of 1 gig ram?
